* Creates a screen reader-accessible description of elements in the canvas.
*
* Elements are shapes or groups of shapes that create meaning together. For

*
* The first parameter, `name`, is the name of the element.
*
* The second parameter, `text`, is the description of the element.
*
* The third parameter, `display`, is optional. It determines how the

* `describe('A description.', LABEL)`, the description will be visible in
* a div element next to the canvas. Using `LABEL` creates unhelpful
* duplicates for screen readers. Only use `LABEL` during development. If
* `FALLBACK` is passed, as in `describe('A description.', FALLBACK)`, the
* description will only be visible to screen readers. This is the default
* mode.

/**
* Creates a screen reader-accessible description of shapes on the canvas.
*
* `gridOutput()` adds a general description, table of shapes, and list of
* shapes to the web page. The general description includes the canvas size,
* canvas color, and number of shapes. For example,
* `gray canvas, 100 by 100 pixels, contains 2 shapes: 1 circle 1 square`.
*
* `gridOutput()` uses its table of shapes as a grid. Each shape in the grid
* is placed in a cell whose row and column correspond to the shape's location
* on the canvas. The grid cells describe the color and type of shape at that
* location. For example, `red circle`. These descriptions can be selected
* individually to get more details. This is different from
* textOutput(), which uses its table as a list.
*
* A list of shapes follows the table. The list describes the color, type,
* location, and area of each shape. For example,
* `red circle, location = middle, area = 3 %`.
*
* The `display` parameter is optional. It determines how the description is
* displayed. If `LABEL` is passed, as in `gridOutput(LABEL)`, the description
* will be visible in a div element next to the canvas. Using `LABEL` creates
* unhelpful duplicates for screen readers. Only use `LABEL` during
* development. If `FALLBACK` is passed, as in `gridOutput(FALLBACK)`, the

* within draw() to clear the display window at the
* beginning of each frame. It can also be used inside
* setup() to set the background on the first frame
* of animation.
*
* The version of `background()` with one parameter interprets the value one
* of four ways. If the parameter is a `Number`, it's interpreted as a grayscale
* value. If the parameter is a `String`, it's interpreted as a CSS color string.
* RGB, RGBA, HSL, HSLA, hex, and named color strings are supported. If the
* parameter is a p5.Color object, it will be used as
* the background color. If the parameter is a
* p5.Image object, it will be used as the background
* image.
*
* The version of `background()` with two parameters interprets the first one
* as a grayscale value. The second parameter sets the alpha (transparency)
* value.
*
* The version of `background()` with three parameters interprets them as RGB,
* HSB, or HSL colors, depending on the current
* colorMode(). By default, colors are specified
* in RGB values. Calling `background(255, 204, 0)` sets the background a bright
* yellow color.

* One of the two render modes in p5.js, used for computationally intensive tasks like 3D rendering and shaders.
*
* `WEBGL` differs from the default `P2D` renderer in the following ways:
*
* - **Coordinate System** - When drawing in `WEBGL` mode, the origin point (0,0,0) is located at the center of the screen, not the top-left corner. See the learn page about coordinates and transformations.
* - **3D Shapes** - `WEBGL` mode can be used to draw 3-dimensional shapes like box(), sphere(), cone(), and more. See the learn page about custom geometry to make more complex objects.
* - **Shape Detail** - When drawing in `WEBGL` mode, you can specify how smooth curves should be drawn by using a `detail` parameter. See the wiki section about shapes for a more information and an example.
* - **Textures** - A texture is like a skin that wraps onto a shape. See the wiki section about textures for examples of mapping images onto surfaces with textures.
* - **Materials and Lighting** - `WEBGL` offers different types of lights like ambientLight() to place around a scene. Materials like specularMaterial() reflect the lighting to convey shape and depth. See the learn page for styling and appearance to experiment with different combinations.
* - **Camera** - The viewport of a `WEBGL` sketch can be adjusted by changing camera attributes. See the learn page section about cameras for an explanation of camera controls.
* - **Text** - `WEBGL` requires opentype/truetype font files to be preloaded using loadFont(). See the wiki section about text for details, along with a workaround.
* - **Shaders** - Shaders are hardware accelerated programs that can be used for a variety of effects and graphics. See the introduction to shaders to get started with shaders in p5.js.
* - **Graphics Acceleration** - `WEBGL` mode uses the graphics card instead of the CPU, so it may help boost the performance of your sketch (example: drawing more shapes on the screen at once).
*
* To learn more about WEBGL mode, check out all the interactive WEBGL tutorials in the "Learn" section of this website, or read the wiki article "Getting started with WebGL in p5".

* @for p5

* This is the main file for the Friendly Error System (FES), containing

*
* The FES may be invoked by a call to either
* (1) _validateParameters, (2) _friendlyFileLoadError, (3) _friendlyError,
* (4) helpForMisusedAtTopLevelCode, or (5) _fesErrorMonitor.
*
* _validateParameters is located in validate_params.js along with other code
* used for parameter validation.
* _friendlyFileLoadError is located in file_errors.js along with other code
* used for dealing with file load errors.
* Apart from this, there's also a file stacktrace.js, which contains the code
* to parse the error stack, borrowed from:
* https://github.com/stacktracejs/stacktrace.js
*
* For more detailed information on the FES functions, including the call
* sequence of each function, please look at the FES Reference + Dev Notes:

* - `channels`: What color channels to store, either `RGB` or `RGBA`. The default is to match the channels in the main canvas (with alpha unless disabled with `setAttributes`.)
* - `depth`: A boolean, whether or not to include a depth buffer. Defaults to true.
* - `depthFormat`: The data format for depth information, either `UNSIGNED_INT` or `FLOAT`. The default is `FLOAT` if available, or `UNSIGNED_INT` otherwise.
* - `stencil`: A boolean, whether or not to include a stencil buffer, which can be used for masking. This may only be used if also using a depth buffer. Defaults to the value of `depth`, which is true if not provided.
* - `antialias`: Boolean or Number, whether or not to render with antialiased edges, and if so, optionally the number of samples to use. Defaults to whether or not the main canvas is antialiased, using a default of 2 samples if so. Antialiasing is only supported when WebGL 2 is available.
* - `width`: The width of the texture. Defaults to matching the main canvas.
* - `height`: The height of the texture. Defaults to matching the main canvas.
* - `density`: The pixel density of the texture. Defaults to the pixel density of the main canvas.
* - `textureFiltering`: Either `LINEAR` (nearby pixels will be interpolated when reading values from the color texture) or `NEAREST` (no interpolation.) Generally, use `LINEAR` when using the texture as an image, and use `NEAREST` if reading the texture as data. Defaults to `LINEAR`.
*
* If `width`, `height`, or `density` are specified, then the framebuffer will

* This function does 3 things:

* 0 <= start < TWO_PI ; start <= stop < start + TWO_PI
*
* This means that the arc rendering functions don't have to be concerned
* with what happens if stop is smaller than start, or if the arc 'goes
* round more than once', etc.: they can just start at start and increase
* until stop and the correct arc will be drawn.
*
* 2. Optionally adjusts the angles within each quadrant to counter the naive
* scaling of the underlying ellipse up from the unit circle. Without

* Draws an arc.
*
* An arc is a section of an ellipse defined by the `x`, `y`, `w`, and
* `h` parameters. `x` and `y` set the location of the arc's center. `w` and
* `h` set the arc's width and height. See
* ellipse() and
* ellipseMode() for more details.
*
* The fifth and sixth parameters, `start` and `stop`, set the angles
* between which to draw the arc. Arcs are always drawn clockwise from
* `start` to `stop`. Angles are always given in radians.
*
* The seventh parameter, `mode`, is optional. It determines the arc's fill
* style. The fill modes are a semi-circle (`OPEN`), a closed semi-circle
* (`CHORD`), or a closed pie segment (`PIE`).
*
* The eighth parameter, `detail`, is also optional. It determines how many
* vertices are used to draw the arc in WebGL mode. The default value is 25.
*
* @method arc
* @param {Number} x x-coordinate of the arc's ellipse.
* @param {Number} y y-coordinate of the arc's ellipse.
* @param {Number} w width of the arc's ellipse by default.
* @param {Number} h height of the arc's ellipse by default.
* @param {Number} start angle to start the arc, specified in radians.
* @param {Number} stop angle to stop the arc, specified in radians.
* @param {Constant} [mode] optional parameter to determine the way of drawing
* the arc. either CHORD, PIE, or OPEN.
* @param {Integer} [detail] optional parameter for WebGL mode only. This is to
* specify the number of vertices that makes up the
* perimeter of the arc. Default value is 25. Won't
* draw a stroke for a detail of more than 50.

/**
* The `p5()` constructor enables you to activate "instance mode" instead of normal
* "global mode". This is an advanced topic. A short description and example is
* included below. Please see
*
* Dan Shiffman's Coding Train video tutorial or this
* tutorial page
* for more info.
*
* By default, all p5.js functions are in the global namespace (i.e. bound to the window
* object), meaning you can call them simply `ellipse()`, `fill()`, etc. However, this
* might be inconvenient if you are mixing with other JS libraries (synchronously or
* asynchronously) or writing long programs of your own. p5.js currently supports a
* way around this problem called "instance mode". In instance mode, all p5 functions
* are bound up in a single variable instead of polluting your global namespace.
*
* Optionally, you can specify a default container for the canvas and any other elements
* to append to with a second argument. You can give the ID of an element in your html,
* or an html node itself.
*
* Note that creating instances like this also allows you to have more than one p5 sketch on
* a single web page, as they will each be wrapped up with their own set up variables. Of
* course, you could also use iframes to have multiple sketches in global mode.
*
* @method p5
* @param {Object} sketch a function containing a p5.js sketch
* @param {String|Object} node ID or pointer to HTML DOM node to contain sketch in
* @example
*
* let x = 0;
*
* function setup() {
* createCanvas(100, 100);
* noLoop();
* }
*
* function draw() {
* background(204);
* x += 1;
* line(x, 0, x, height);
* }
*
* function mousePressed() {
* redraw(5);
* }
*
*
* const s = p => {
* let x = 100;
* let y = 100;
*
* p.setup = function() {
* p.createCanvas(700, 410);
* };
*
* p.draw = function() {
* p.background(0);
* p.fill(255);
* p.rect(x, y, 50, 50);
* };
* };
*
* new p5(s); // invoke p5

* If an existing `<div></div>` or `<span></span>`
* element is passed, as in `let myRadio = createSelect(container)`, it will
* become the radio button's parent element.
*
* Radio buttons extend the p5.Element class with a few
* helpful methods for managing options:
* - `myRadio.option(value, [label])` adds an option to the menu. The first paremeter, `value`, is a string that sets the option's value and label. The second parameter, `label`, is optional. If provided, it sets the label displayed for the `value`. If an option with `value` already exists, its label is changed and its value is returned.
* - `myRadio.value()` returns the currently-selected option's value.
* - `myRadio.selected()` returns the currently-selected option.
* - `myRadio.selected(value)` selects the given option and returns it as an `HTMLInputElement`.
* - `myRadio.disable(shouldDisable)` enables the entire radio button if `true` is passed and disables it if `false` is passed.

* - p5.Texture
* - p5.Framebuffer

*
* The second and third parameters, `dx` and `dy`, set the coordinates of the

* imageMode() for other ways to position images.
*
* Here's a diagram that explains how optional parameters work in `image()`:
*
* 
*
* The fourth and fifth parameters, `dw` and `dh`, are optional. They set the
* the width and height to draw the destination image. By default, `image()`
* draws the full source image at its original size.
*
* The sixth and seventh parameters, `sx` and `sy`, are also optional.
* These coordinates define the top left corner of a subsection to draw from
* the source image.
*
* The eighth and ninth parameters, `sw` and `sh`, are also optional.
* They define the width and height of a subsection to draw from the source
* image. By default, `image()` draws the full subsection that begins at
* `(sx, sy)` and extends to the edges of the source image.
*
* The ninth parameter, `fit`, is also optional. It enables a subsection of
* the source image to be drawn without affecting its aspect ratio. If
* `CONTAIN` is passed, the full subsection will appear within the destination
* rectangle. If `COVER` is passed, the subsection will completely cover the
* destination rectangle. This may have the effect of zooming into the
* subsection.
*
* The tenth and eleventh paremeters, `xAlign` and `yAlign`, are also
* optional. They determine how to align the fitted subsection. `xAlign` can
* be set to either `LEFT`, `RIGHT`, or `CENTER`. `yAlign` can be set to
* either `TOP`, `BOTTOM`, or `CENTER`. By default, both `xAlign` and `yAlign`
* are set to `CENTER`.

/**
* Captures a sequence of frames from the canvas that can be saved as images.
*
* `saveFrames()` creates an array of frame objects. Each frame is stored as
* an object with its file type, file name, and image data as a string. For
* example, the first saved frame might have the following properties:
*
* `{ ext: 'png', filenmame: 'frame0', imageData: 'data:image/octet-stream;base64, abc123' }`.
*
* The first parameter, `filename`, sets the prefix for the file names. For
* example, setting the prefix to `'frame'` would generate the image files
* `frame0.png`, `frame1.png`, and so on.
*
* The second parameter, `extension`, sets the file type to either `'png'` or
* `'jpg'`.
*
* The third parameter, `duration`, sets the duration to record in seconds.
* The maximum duration is 15 seconds.
*
* The fourth parameter, `framerate`, sets the number of frames to record per
* second. The maximum frame rate value is 22. Limits are placed on `duration`
* and `framerate` to avoid using too much memory. Recording large canvases
* can easily crash sketches or even web browsers.
*
* The fifth parameter, `callback`, is optional. If a function is passed,
* image files won't be saved by default. The callback function can be used
* to process an array containing the data for each captured frame. The array
* of image data contains a sequence of objects with three properties for each
* frame: `imageData`, `filename`, and `extension`.
*
* Note: Frames are downloaded as individual image files by default.
*
* @method saveFrames
* @param {String} filename prefix of file name.
* @param {String} extension file extension, either 'jpg' or 'png'.
* @param {Number} duration duration in seconds to record. This parameter will be constrained to be less or equal to 15.
* @param {Number} framerate number of frames to save per second. This parameter will be constrained to be less or equal to 22.
* @param {function(Array)} [callback] callback function that will be executed
to handle the image data. This function
should accept an array as argument. The
array will contain the specified number of
frames of objects. Each object has three
properties: `imageData`, `filename`, and `extension`.
* @example
*
* function setup() {
* let cnv = createCanvas(100, 100);
*
* background(255);
*
* // Save the canvas to 'myCanvas.jpg'.
* saveCanvas(cnv, 'myCanvas', 'jpg');
*
* describe('A white square.');
* }
*
*
*
*
*
* function setup() {
* createCanvas(100, 100);
*
* describe('A square repeatedly changes color from blue to pink.');
* }
*
* function draw() {
* let r = frameCount % 255;
* let g = 50;
* let b = 100;
* background(r, g, b);
* }
*
* // Save the frames when the user presses the 's' key.
* function keyPressed() {
* if (key === 's') {
* saveFrames('frame', 'png', 1, 5);
* }
* }

* Loads an image to create a p5.Image object.
*
* `loadImage()` interprets the first parameter one of three ways. If the path
* to an image file is provided, `loadImage()` will load it. Paths to local
* files should be relative, such as `'assets/thundercat.jpg'`. URLs such as
* `'https://example.com/thundercat.jpg'` may be blocked due to browser
* security. Raw image data can also be passed as a base64 encoded image in
* the form `'data:image/png;base64,arandomsequenceofcharacters'`.
*
* The second parameter is optional. If a function is passed, it will be
* called once the image has loaded. The callback function can optionally use
* the new p5.Image object.
*
* The third parameter is also optional. If a function is passed, it will be
* called if the image fails to load. The callback function can optionally use
* the event error.
*
* Images can take time to load. Calling `loadImage()` in
* preload() ensures images load before they're
* used in setup() or draw().
*
* @method loadImage
* @param {String} path path of the image to be loaded or base64 encoded image.
* @param {function(p5.Image)} [successCallback] function called with
* p5.Image once it
* loads.
* @param {function(Event)} [failureCallback] function called with event
* error if the image fails to load.
* @return {p5.Image} the p5.Image object.
*

*
* The third parameter, `options`, is optional. If an object is passed,

* `notificationDuration`, a Number that defines how long in seconds the final notification
* will live. By default it's `0`, meaning the notification will never be removed;

* These coordinates define the top left corner of a subsection to draw from
* the source image.
*
* The eighth and ninth parameters, `sw` and `sh`, are also optional.
* They define the width and height of a subsection to draw from the source
* image. By default, `image()` draws the full subsection that begins at
* `(sx, sy)` and extends to the edges of the source image.
*
* The ninth parameter, `fit`, is also optional. It enables a subsection of
* the source image to be drawn without affecting its aspect ratio. If
* `CONTAIN` is passed, the full subsection will appear within the destination
* rectangle. If `COVER` is passed, the subsection will completely cover the
* destination rectangle. This may have the effect of zooming into the
* subsection.
*
* The tenth and eleventh paremeters, `xAlign` and `yAlign`, are also
* optional. They determine how to align the fitted subsection. `xAlign` can
* be set to either `LEFT`, `RIGHT`, or `CENTER`. `yAlign` can be set to
* either `TOP`, `BOTTOM`, or `CENTER`. By default, both `xAlign` and `yAlign`
* are set to `CENTER`.

* Tints images using a color.

* The version of `tint()` with two parameters uses the first one as a
* grayscale value and the second as an alpha value. For example, calling
* `tint(255, 128)` will make an image 50% transparent.
*
* The version of `tint()` with three parameters interprets them as RGB or
* HSB values, depending on the current
* colorMode(). The optional fourth parameter
* sets the alpha value. For example, `tint(255, 0, 0, 100)` will give images

* `GRAY`
* Converts the image to grayscale. No parameter is used.
*
* `THRESHOLD`
* Converts the image to black and white. Pixels with a grayscale value

*
* `BLUR`
* Blurs the image. The level of blurring is specified by a blur radius. Larger
* values increase the blur. The default value is 4. A gaussian blur is used
* in `P2D` mode. A box blur is used in `WEBGL` mode.

/**
* An array containing the color of each pixel on the canvas.
*
* Colors are stored as numbers representing red, green, blue, and alpha
* (RGBA) values. `pixels` is a one-dimensional array for performance reasons.
*
* Each pixel occupies four elements in the `pixels` array, one for each RGBA
* value. For example, the pixel at coordinates (0, 0) stores its RGBA values
* at `pixels[0]`, `pixels[1]`, `pixels[2]`, and `pixels[3]`, respectively.
* The next pixel at coordinates (1, 0) stores its RGBA values at `pixels[4]`,
* `pixels[5]`, `pixels[6]`, and `pixels[7]`. And so on. The `pixels` array
* for a 100×100 canvas has 100 × 100 × 4 = 40,000 elements.
*
* Some displays use several smaller pixels to set the color at a single
* point. The pixelDensity() function returns
* the pixel density of the canvas. High density displays often have a
* pixelDensity() of 2. On such a display, the
* `pixels` array for a 100×100 canvas has 200 × 200 × 4 =
* 160,000 elements.
*
* Accessing the RGBA values for a point on the canvas requires a little math
* as shown below. The loadPixels() function
* must be called before accessing the `pixels` array. The
* updatePixels() function must be called
* after any changes are made.
*

*
* A vector can be thought of in different ways. In one view, a vector is like

* direction. This view is helpful for programming motion.
*
* A vector's components determine its magnitude and direction. For example,
* calling `createVector(3, 4)` creates a new
* p5.Vector object with an x-component of 3 and a
* y-component of 4. From the origin, this vector's tip is 3 units to the
* right and 4 units down.
*
* p5.Vector objects are often used to program
* motion because they simplify the math. For example, a moving ball has a
* position and a velocity. Position describes where the ball is in space. The
* ball's position vector extends from the origin to the ball's center.
* Velocity describes the ball's speed and the direction it's moving. If the
* ball is moving straight up, its velocity vector points straight up. Adding
* the ball's velocity vector to its position vector moves it, as in
* `pos.add(vel)`. Vector math relies on methods inside the
* p5.Vector class.

* Returns random numbers that can be tuned to feel organic.
*
* Values returned by random() and
* randomGaussian() can change by large
* amounts between function calls. By contrast, values returned by `noise()`
* can be made "smooth". Calls to `noise()` with similar inputs will produce
* similar outputs. `noise()` is used to create textures, motion, shapes,
* terrains, and so on. Ken Perlin invented `noise()` while animating the
* original Tron film in the 1980s.
*
* `noise()` always returns values between 0 and 1. It returns the same value
* for a given input while a sketch is running. `noise()` produces different
* results each time a sketch runs. The
* noiseSeed() function can be used to generate
* the same sequence of Perlin noise values each time a sketch runs.
*
* The character of the noise can be adjusted in two ways. The first way is to
* scale the inputs. `noise()` interprets inputs as coordinates. The sequence
* of noise values will be smoother when the input coordinates are closer. The
* second way is to use the noiseDetail()
* function.
*
* The version of `noise()` with one parameter computes noise values in one
* dimension. This dimension can be thought of as space, as in `noise(x)`, or
* time, as in `noise(t)`.
*
* The version of `noise()` with two parameters computes noise values in two
* dimensions. These dimensions can be thought of as space, as in
* `noise(x, y)`, or space and time, as in `noise(x, t)`.
*
* The version of `noise()` with three parameters computes noise values in
* three dimensions. These dimensions can be thought of as space, as in
* `noise(x, y, z)`, or space and time, as in `noise(x, y, t)`.

*
* By default, noise values are created by combining four octaves. Each higher

* noise() will use six octaves. Each higher octave

/**
* A class to describe a two or three-dimensional vector.
*
* A vector can be thought of in different ways. In one view, a vector is like
* an arrow pointing in space. Vectors have both magnitude (length) and
* direction.
*
* `p5.Vector` objects are often used to program motion because they simplify
* the math. For example, a moving ball has a position and a velocity.
* Position describes where the ball is in space. The ball's position vector
* extends from the origin to the ball's center. Velocity describes the ball's
* speed and the direction it's moving. If the ball is moving straight up, its
* velocity vector points straight up. Adding the ball's velocity vector to
* its position vector moves it, as in `pos.add(vel)`. Vector math relies on
* methods inside the `p5.Vector` class.
*
* Note: createVector() is the recommended way
* to make an instance of this class.
*
* @class p5.Vector
* @constructor
* @param {Number} [x] x component of the vector.
* @param {Number} [y] y component of the vector.

* @example
*
* function setup() {
* createCanvas(100, 100);
*
* background(200);
*
* // Set the noise seed for consistent results.
* noiseSeed(99);
*
* describe('A black rectangle that grows randomly, first to the right and then to the left.');
* }
*
* function draw() {
* // Set the noise level and scale.
* let noiseLevel = 100;
* let noiseScale = 0.005;
*
* // Scale the input coordinate.
* let nt = noiseScale * frameCount;

* Draws text to the canvas.
*
* The first parameter, `str`, is the text to be drawn. The second and third

* corner. See textAlign() for other ways to
* align text.
*
* The fourth and fifth parameters, `maxWidth` and `maxHeight`, are optional.
* They set the dimensions of the invisible rectangle containing the text. By
* default, they set its maximum width and height. See
* rectMode() for other ways to define the
* rectangular text box. Text will wrap to fit within the text box. Text
* outside of the box won't be drawn.
*
* Text can be styled a few ways. Call the fill()
* function to set the text's fill color. Call
* stroke() and
* strokeWeight() to set the text's outline.
* Call textSize() and
* textFont() to set the text's size and font,
* respectively.
*
* Note: `WEBGL` mode only supports fonts loaded with
* loadFont(). Calling
* stroke() has no effect in `WEBGL` mode.

* @param {Object} [options] An optional object that can contain additional settings,

* Setting this to true makes mobile interactions smoother by preventing
* accidental interactions with the page while orbiting. But if you're already
* doing it via css or want the default touch actions, consider setting it to false.
* freeRotation - Boolean, default value is false.
* By default, horizontal movement of the mouse or touch pointer rotates the camera
* around the y-axis, and vertical movement rotates the camera around the x-axis.
* But if setting this option to true, the camera always rotates in the direction
* the pointer is moving. For zoom and move, the behavior is the same regardless of
* true/false.

/**
* debugMode() helps visualize 3D space by adding a grid to indicate where the
* ‘ground’ is in a sketch and an axes icon which indicates the +X, +Y, and +Z
* directions. This function can be called without parameters to create a
* default grid and axes icon, or it can be called according to the examples
* above to customize the size and position of the grid and/or axes icon. The
* grid is drawn using the most recently set stroke color and weight. To
* specify these parameters, add a call to stroke() and strokeWeight()
* just before the end of the draw() loop.
*
* By default, the grid will run through the origin (0,0,0) of the sketch
* along the XZ plane
* and the axes icon will be offset from the origin. Both the grid and axes
* icon will be sized according to the current canvas size. Note that because the
* grid runs parallel to the default camera view, it is often helpful to use
* debugMode along with orbitControl to allow full view of the grid.
* @method debugMode

*
* function setup() {
* createCanvas(100, 100, WEBGL);

* // will be the direction the mouse or touch pointer moves, not around the X or Y axis.

* Load a 3d model from an OBJ or STL file.
*
* loadModel() should be placed inside of preload().
* This allows the model to load fully before the rest of your code is run.
*
* One of the limitations of the OBJ and STL format is that it doesn't have a built-in
* sense of scale. This means that models exported from different programs might
* be very different sizes. If your model isn't displaying, try calling
* loadModel() with the normalized parameter set to true. This will resize the
* model to a scale appropriate for p5. You can also make additional changes to
* the final size of your model with the scale() function.
*
* Also, the support for colored STL files is not present. STL files with color will be
* rendered without color properties.
*
* Options can include:
* - `path`: Specifies the location or path of the 3D model file for loading.
* - `normalize`: Enables standardized size scaling during loading if set to true.
* - `successCallback`: Callback for post-loading actions with the 3D model object.
* - `failureCallback`: Handles errors if model loading fails, receiving an event error.
* - `fileType`: Defines the file extension of the model.
* - `flipU`: Flips the U texture coordinates of the model.
* - `flipV`: Flips the V texture coordinates of the model.
*
* @method loadModel
* @param {String} path Path of the model to be loaded
* @param {Boolean} normalize If true, scale the model to a

* Sets a perspective projection for the current camera in a 3D sketch.

* - `fov` : The default field of view for the camera is such that the full height of renderer is visible when it is positioned at a default distance of 800 units from the camera.
* - `aspect` : The default aspect ratio is the ratio of renderer's width to renderer's height.
* - `near` : The default value for the near clipping plane is 80, which is 0.1 times the default distance from the camera to its subject.
* - `far` : The default value for the far clipping plane is 8000, which is 10 times the default distance from the camera to its subject.
*
* If you prefer a fixed field of view, follow these steps:

* 2. To ensure that you can see the entire width across horizontally and height across vertically, place the camera a distance of `(height / 2) / tan(fovy / 2)` back from its subject.

* Used to set the uniforms of a
* p5.Shader object.
*
* Uniforms are used as a way to provide shader programs
* (which run on the GPU) with values from a sketch
* (which runs on the CPU).
*
* Here are some examples of uniforms you can make:
* - booleans
* - Example: `setUniform('x', true)` becomes `uniform float x` with the value `1.0`
* - numbers
* - Example: `setUniform('x', -2)` becomes `uniform float x` with the value `-2.0`
* - arrays of numbers
* - Example: `setUniform('x', [0, 0.5, 1])` becomes `uniform vec3 x` with the value `vec3(0.0, 0.5, 1.0)`
* - a p5.Image, p5.Graphics, p5.MediaElement, or p5.Texture
* - Example: `setUniform('x', img)` becomes `uniform sampler2D x`
*
* @method setUniform
* @chainable
* @param {String} uniformName the name of the uniform.
* Must correspond to the name used in the vertex and fragment shaders
* @param {Boolean|Number|Number[]|p5.Image|p5.Graphics|p5.MediaElement|p5.Texture}
* data The value to assign to the uniform. This can be
* a boolean (true/false), a number, an array of numbers, or
* an image (p5.Image, p5.Graphics, p5.MediaElement, p5.Texture)
*
* @example
*
* let graphic = createGraphics(200, 200, WEBGL);
* let graphicShader = graphic.createShader(vert, frag);
* graphic.shader(graphicShader); // Use graphicShader on the graphic
*
* let mainShader = graphicShader.copyToContext(window);
* shader(mainShader); // Use `mainShader` on the main canvas
*
*
*
*
* @alt
* canvas toggles between a circular gradient of orange and blue vertically. and a circular gradient of red and green moving horizontally when mouse is clicked/pressed.
