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\".

An array containing the color of each pixel on the canvas. Colors are\nstored as numbers representing red, green, blue, and alpha (RGBA) values.\npixels is a one-dimensional array for performance reasons.

Each pixel occupies four elements in the pixels array, one for each RGBA\nvalue. For example, the pixel at coordinates (0, 0) stores its RGBA values\nat pixels[0], pixels[1], pixels[2], and pixels[3], respectively.\nThe next pixel at coordinates (1, 0) stores its RGBA values at pixels[4],\npixels[5], pixels[6], and pixels[7]. And so on. The pixels array\nfor a 100\u00d7100 canvas has 100 \u00d7 100 \u00d7 4 = 40,000 elements.

Some displays use several smaller pixels to set the color at a single\npoint. The pixelDensity() function returns\nthe pixel density of the canvas. High density displays often have a\npixelDensity() of 2. On such a display, the\npixels array for a 100\u00d7100 canvas has 200 \u00d7 200 \u00d7 4 =\n160,000 elements.

Accessing the RGBA values for a point on the canvas requires a little math\nas shown below. The loadPixels() function\nmust be called before accessing the pixels array. The\nupdatePixels() function must be called\nafter any changes are made.

An array containing the color of each pixel in the\np5.Image object. Colors are stored as numbers\nrepresenting red, green, blue, and alpha (RGBA) values. img.pixels is a\none-dimensional array for performance reasons.

Each pixel occupies four elements in the pixels array, one for each\nRGBA value. For example, the pixel at coordinates (0, 0) stores its\nRGBA values at img.pixels[0], img.pixels[1], img.pixels[2],\nand img.pixels[3], respectively. The next pixel at coordinates (1, 0)\nstores its RGBA values at img.pixels[4], img.pixels[5],\nimg.pixels[6], and img.pixels[7]. And so on. The img.pixels array\nfor a 100\u00d7100 p5.Image object has\n100 \u00d7 100 \u00d7 4 = 40,000 elements.

Accessing the RGBA values for a pixel in the\np5.Image object requires a little math as\nshown below. The img.loadPixels()\nmethod must be called before accessing the img.pixels array. The\nimg.updatePixels() method must be\ncalled after any changes are made.

The p5() constructor enables you to activate \"instance mode\" instead of normal\n\"global mode\". This is an advanced topic. A short description and example is\nincluded below. Please see\n\nDan Shiffman's Coding Train video tutorial or this\ntutorial page\nfor more info.

By default, all p5.js functions are in the global namespace (i.e. bound to the window\nobject), meaning you can call them simply ellipse(), fill(), etc. However, this\nmight be inconvenient if you are mixing with other JS libraries (synchronously or\nasynchronously) or writing long programs of your own. p5.js currently supports a\nway around this problem called \"instance mode\". In instance mode, all p5 functions\nare 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\nto append to with a second argument. You can give the ID of an element in your html,\nor an html node itself.

Note that creating instances like this also allows you to have more than one p5 sketch on\na single web page, as they will each be wrapped up with their own set up variables. Of\ncourse, you could also use iframes to have multiple sketches in global mode.

Sets the color used for the background of the canvas. By default, the\nbackground is transparent. This function is typically used within\ndraw() to clear the display window at the beginning\nof each frame. It can also be used inside setup() to\nset the background on the first frame of animation.

The version of background() with one parameter interprets the value one of four\nways.

RGB, RGBA,\nHSL, HSLA, hex, and named color strings are supported.

The version of background() with two parameters interprets the first one as a\ngrayscale value. The second parameter sets the alpha (transparency) value.

The version of background() with three parameters interprets them as RGB, HSB,\nor HSL colors, depending on the current colorMode().\nBy default, colors are specified in RGB values. Calling background(255, 204, 0)\nsets the background a bright yellow color.

Note: Variables declared within setup() are not accessible within other\nfunctions, including draw().

Called directly after setup(), the draw() function continuously executes\nthe lines of code contained inside its block until the program is stopped\nor noLoop() is called. Note if noLoop() is called in setup(), draw() will\nstill be executed once before stopping. draw() is called automatically and\nshould never be called explicitly.

It should always be controlled with noLoop(), redraw() and loop(). After\nnoLoop() stops the code in draw() from executing, redraw() causes the\ncode inside draw() to execute once, and loop() will cause the code\ninside draw() to resume executing continuously.

The number of times draw() executes in each second may be controlled with\nthe frameRate() function.

There can only be one draw() function for each sketch, and draw() must\nexist if you want the code to run continuously, or to process events such\nas mousePressed(). Sometimes, you might have an empty call to draw() in\nyour program, as shown in the above example.

It is important to note that the drawing coordinate system will be reset\nat the beginning of each draw() call. If any transformations are performed\nwithin draw() (ex: scale, rotate, translate), their effects will be\nundone at the beginning of draw(), so transformations will not accumulate\nover time. On the other hand, styling applied (ex: fill, stroke, etc) will\nremain in effect.

A WebGL canvas will use a WebGL2 context if it is supported by the browser.\nCheck the webglVersion property to check what\nversion is being used, or call setAttributes({ version: 1 })\nto create a WebGL1 context.

The system variables width and height are set by the parameters passed to this\nfunction. If createCanvas() is not used, the\nwindow will be given a default size of 100\u00d7100 pixels.

Optionally, an existing canvas can be passed using a selector, ie. document.getElementById('').\nIf specified, avoid using setAttributes() afterwards, as this will remove and recreate the existing canvas.

For more ways to position the canvas, see the\n\npositioning the canvas wiki page.

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\nkeep that size until manually changed. Otherwise, it will be autosized, and\nit will update to match the main canvas's size and density when the main\ncanvas changes.

The push() function saves the current drawing style\nsettings and transformations, while pop() restores\nthese settings. Note that these functions are always used together. They allow\nyou to change the style and transformation settings and later return to what\nyou had. When a new state is started with push(), it\nbuilds on the current style and transform information. The push()\nand pop() functions can be embedded to provide more\ncontrol. (See the second example for a demonstration.)

In WEBGL mode additional style settings are stored. These are controlled by\nthe following functions:\nsetCamera(),\nambientLight(),\ndirectionalLight(),\npointLight(),\ntexture(),\nspecularMaterial(),\nshininess(),\nnormalMaterial() and\nshader().

Radio buttons extend the p5.Element class with a few\nhelpful 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.

Sets the element's width and height.

Calling myElement.size() without an argument returns the element's size\nas an object with the properties width and height. For example,\n{ width: 20, height: 10 }.

The first parameter, width, is optional. It's a number used to set the\nelement's width. Calling myElement.size(10)

The constant AUTO can be used to adjust one dimension at a time while\nmaintaining the aspect ratio, which is width / height. For example,\nconsider an element that's 200 pixels wide and 100 pixels tall. Calling\nmyElement.size(20, AUTO) sets the width to 20 pixels and height to 10\npixels.

Applies an image filter to the canvas. The preset options are:

INVERT\nInverts the colors in the image. No parameter is used.

GRAY\nConverts the image to grayscale. No parameter is used.

THRESHOLD\nConverts the image to black and white. Pixels with a grayscale value\nabove a given threshold are converted to white. The rest are converted to\nblack. The threshold must be between 0.0 (black) and 1.0 (white). If no\nvalue is specified, 0.5 is used.

OPAQUE\nSets the alpha channel to entirely opaque. No parameter is used.

POSTERIZE\nLimits the number of colors in the image. Each color channel is limited to\nthe number of colors specified. Values between 2 and 255 are valid, but\nresults are most noticeable with lower values. The default value is 4.

BLUR\nBlurs the image. The level of blurring is specified by a blur radius. Larger\nvalues increase the blur. The default value is 4. A gaussian blur is used\nin P2D mode. A box blur is used in WEBGL mode.

ERODE\nReduces the light areas. No parameter is used.

DILATE\nIncreases the light areas. No parameter is used.

filter() uses WebGL in the background by default because it's faster.\nThis can be disabled in P2D mode by adding a false argument, as in\nfilter(BLUR, false). This may be useful to keep computation off the GPU\nor to work around a lack of WebGL support.

In WEBGL mode, filter() can also use custom shaders. See\ncreateFilterShader() for more\ninformation.

Table only looks for a header row if the 'header' option is\nincluded.

This method is asynchronous, meaning it may not finish before the next\nline in your sketch is executed. Calling loadTable() inside preload()\nguarantees to complete the operation before setup() and draw() are called.\nOutside of preload(), you may supply a callback function to handle the\nobject:

All files loaded and saved use UTF-8 encoding. This method is suitable for fetching files up to size of 64MB.

Returns random numbers that can be tuned to feel more organic. The values\nreturned will always be between 0 and 1.

Values returned by random() and\nrandomGaussian() can change by large\namounts between function calls. By contrast, values returned by noise()\ncan be made \"smooth\". Calls to noise() with similar inputs will produce\nsimilar outputs. noise() is used to create textures, motion, shapes,\nterrains, and so on. Ken Perlin invented noise() while animating the\noriginal Tron film in the 1980s.

noise() returns the same value for a given input while a sketch is\nrunning. It produces different results each time a sketch runs. The\nnoiseSeed() function can be used to generate\nthe 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\nscale the inputs. noise() interprets inputs as coordinates. The sequence\nof noise values will be smoother when the input coordinates are closer. The\nsecond way is to use the noiseDetail()\nfunction.

The version of noise() with one parameter computes noise values in one\ndimension. This dimension can be thought of as space, as in noise(x), or\ntime, as in noise(t).

The version of noise() with two parameters computes noise values in two\ndimensions. These dimensions can be thought of as space, as in\nnoise(x, y), or space and time, as in noise(x, t).

The version of noise() with three parameters computes noise values in\nthree dimensions. These dimensions can be thought of as space, as in\nnoise(x, y, z), or space and time, as in noise(x, y, t).

Perlin noise values are created by adding layers of noise together. The\nnoise layers, called octaves, are similar to harmonics in music. Lower\noctaves contribute more to the output signal. They define the overall\nintensity of the noise. Higher octaves create finer-grained details.

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

Returns a random number or a random element from an array.

random() follows uniform distribution, which means that all outcomes are\nequally likely. When random() is used to generate numbers, all\nnumbers in the output range are equally likely to be returned. When\nrandom() is used to select elements from an array, all elements are\nequally likely to be chosen.

By default, random() produces different results each time a sketch runs.\nThe randomSeed() function can be used to\ngenerate the same sequence of numbers or choices each time a sketch runs.

The version of random() with no parameters returns a random number from 0\nup to but not including 1.

The version of random() with one parameter works one of two ways. If the\nargument passed is a number, random() returns a random number from 0 up\nto but not including the number. For example, calling random(5) returns\nvalues between 0 and 5. If the argument passed is an array, random()\nreturns a random element from that array. For example, calling\nrandom(['\ud83e\udd81', '\ud83d\udc2f', '\ud83d\udc3b']) returns either a lion, tiger, or bear emoji.

The version of random() with two parameters returns a random number from\na given range. The arguments passed set the range's lower and upper bounds.\nFor example, calling random(-5, 10.2) returns values from -5 up to but\nnot including 10.2.

Returns a random number fitting a Gaussian, or normal, distribution. Normal\ndistributions look like bell curves when plotted. Values from a normal\ndistribution cluster around a central value called the mean. The cluster's\nstandard deviation describes its spread.

By default, randomGaussian() produces different results each time a\nsketch runs. The randomSeed() function can be\nused to generate the same sequence of numbers each time a sketch runs.

There's no minimum or maximum value that randomGaussian() might return.\nValues far from the mean are very unlikely and values near the mean are\nvery likely.

The version of randomGaussian() with no parameters returns values with a\nmean of 0 and standard deviation of 1.

The version of randomGaussian() with one parameter interprets the\nargument passed as the mean. The standard deviation is 1.

The version of randomGaussian() with two parameters interprets the first\nargument passed as the mean and the second as the standard deviation.

WORD starts new lines of text at spaces. If a string of text doesn't\nhave spaces, it may overflow the text box and the canvas. This is the\ndefault style.

CHAR starts new lines as needed to stay within the text box.

textWrap() only works when the maximum width is set for a text box. For\nexample, calling text('Have a wonderful day', 0, 10, 100) sets the\nmaximum width to 100 pixels.

Both the grid and axes\nicon will be sized according to the current canvas size.

Load a 3d model from an OBJ or STL file.

Sets the metalness property of a material used in 3D rendering.

The metalness property controls the degree to which the material\nappears metallic. A higher metalness value makes the material look\nmore metallic, while a lower value makes it appear less metallic.

The default and minimum value is 0, indicating a non-metallic appearance.

Unlike other materials, metals exclusively rely on reflections, particularly\nthose produced by specular lights (mirrorLike lights). They don't incorporate\ndiffuse or ambient lighting. Metals use a fill color to influence the overall\ncolor of their reflections. Pick a fill color, and you can easily change the\nappearance of the metal surfaces. When no fill color is provided, it defaults\nto using white.

Sets a perspective projection for the current camera in a 3D sketch.\nThis projection represents depth through foreshortening: objects\nthat are close to the camera appear their actual size while those\nthat are further away from the camera appear smaller.

The parameters to this function define the viewing frustum\n(the truncated pyramid within which objects are seen by the camera) through\nvertical field of view, aspect ratio (usually width/height), and near and far\nclipping planes.

If no parameters are given, the default values are used as:

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:

Choose your desired field of view angle (fovy). This is how wide the camera can see.
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.
Call perspective with the chosen field of view, canvas aspect ratio, and near/far values:\nperspective(fovy, width / height, cameraDistance / 10, cameraDistance * 10);
