The + primary way of interacting with a promise is through its `then` method, which + registers callbacks to receive either a promise's eventual value or the reason + why the promise cannot be fulfilled. + + Terminology + ----------- + + - `promise` is an object or function with a `then` method whose behavior conforms to this specification. + - `thenable` is an object or function that defines a `then` method. + - `value` is any legal JavaScript value (including undefined, a thenable, or a promise). + - `exception` is a value that is thrown using the throw statement. + - `reason` is a value that indicates why a promise was rejected. + - `settled` the final resting state of a promise, fulfilled or rejected. + + A promise can be in one of three states: pending, fulfilled, or rejected. + + Promises that are fulfilled have a fulfillment value and are in the fulfilled + state. Promises that are rejected have a rejection reason and are in the + rejected state. A fulfillment value is never a thenable. + + Promises can also be said to *resolve* a value. If this value is also a + promise, then the original promise's settled state will match the value's + settled state. So a promise that *resolves* a promise that rejects will + itself reject, and a promise that *resolves* a promise that fulfills will + itself fulfill. + + + Basic Usage: + ------------ + + ```js + let promise = new Promise(function(resolve, reject) { + // on success + resolve(value); + + // on failure + reject(reason); + }); + + promise.then(function(value) { + // on fulfillment + }, function(reason) { + // on rejection + }); + ``` + + Advanced Usage: + --------------- + + Promises shine when abstracting away asynchronous interactions such as + `XMLHttpRequest`s. + + ```js + function getJSON(url) { + return new Promise(function(resolve, reject){ + let xhr = new XMLHttpRequest(); + + xhr.open('GET', url); + xhr.onreadystatechange = handler; + xhr.responseType = 'json'; + xhr.setRequestHeader('Accept', 'application/json'); + xhr.send(); + + function handler() { + if (this.readyState === this.DONE) { + if (this.status === 200) { + resolve(this.response); + } else { + reject(new Error('getJSON: `' + url + '` failed with status: [' + this.status + ']')); + } + } + }; + }); + } + + getJSON('/posts.json').then(function(json) { + // on fulfillment + }, function(reason) { + // on rejection + }); + ``` + + Unlike callbacks, promises are great composable primitives. + + ```js + Promise.all([ + getJSON('/posts'), + getJSON('/comments') + ]).then(function(values){ + values[0] // => postsJSON + values[1] // => commentsJSON + + return values; + }); + ``` + + @class Promise + @param {Function} resolver + Useful for tooling. + @constructor + */ + + var Promise$1 = function () { + function Promise(resolver) { + this[PROMISE_ID] = nextId(); + this._result = this._state = undefined; + this._subscribers = [ + ]; + if (noop !== resolver) { + typeof resolver !== 'function' && needsResolver(); + this instanceof Promise ? initializePromise(this, resolver) : needsNew(); + } + } /** + The primary way of interacting with a promise is through its `then` method, + which registers callbacks to receive either a promise's eventual value or the + reason why the promise cannot be fulfilled. + ```js + findUser().then(function(user){ + // user is available + }, function(reason){ + // user is unavailable, and you are given the reason why + }); + ``` + Chaining + -------- + The return value of `then` is itself a promise. This second, 'downstream' + promise is resolved with the return value of the first promise's fulfillment + or rejection handler, or rejected if the handler throws an exception. + ```js + findUser().then(function (user) { + return user.name; + }, function (reason) { + return 'default name'; + }).then(function (userName) { + // If `findUser` fulfilled, `userName` will be the user's name, otherwise it + // will be `'default name'` + }); + findUser().then(function (user) { + throw new Error('Found user, but still unhappy'); + }, function (reason) { + throw new Error('`findUser` rejected and we're unhappy'); + }).then(function (value) { + // never reached + }, function (reason) { + // if `findUser` fulfilled, `reason` will be 'Found user, but still unhappy'. + // If `findUser` rejected, `reason` will be '`findUser` rejected and we're unhappy'. + }); + ``` + If the downstream promise does not specify a rejection handler, rejection reasons will be propagated further downstream. + ```js + findUser().then(function (user) { + throw new PedagogicalException('Upstream error'); + }).then(function (value) { + // never reached + }).then(function (value) { + // never reached + }, function (reason) { + // The `PedgagocialException` is propagated all the way down to here + }); + ``` + Assimilation + ------------ + Sometimes the value you want to propagate to a downstream promise can only be + retrieved asynchronously. This can be achieved by returning a promise in the + fulfillment or rejection handler. The downstream promise will then be pending + until the returned promise is settled. This is called *assimilation*. + ```js + findUser().then(function (user) { + return findCommentsByAuthor(user); + }).then(function (comments) { + // The user's comments are now available + }); + ``` + If the assimliated promise rejects, then the downstream promise will also reject. + ```js + findUser().then(function (user) { + return findCommentsByAuthor(user); + }).then(function (comments) { + // If `findCommentsByAuthor` fulfills, we'll have the value here + }, function (reason) { + // If `findCommentsByAuthor` rejects, we'll have the reason here + }); + ``` + Simple Example + -------------- + Synchronous Example + ```javascript + let result; + try { + result = findResult(); + // success + } catch(reason) { + // failure + } + ``` + Errback Example + ```js + findResult(function(result, err){ + if (err) { + // failure + } else { + // success + } + }); + ``` + Promise Example; + ```javascript + findResult().then(function(result){ + // success + }, function(reason){ + // failure + }); + ``` + Advanced Example + -------------- + Synchronous Example + ```javascript + let author, books; + try { + author = findAuthor(); + books = findBooksByAuthor(author); + // success + } catch(reason) { + // failure + } + ``` + Errback Example + ```js + function foundBooks(books) { + } + function failure(reason) { + } + findAuthor(function(author, err){ + if (err) { + failure(err); + // failure + } else { + try { + findBoooksByAuthor(author, function(books, err) { + if (err) { + failure(err); + } else { + try { + foundBooks(books); + } catch(reason) { + failure(reason); + } + } + }); + } catch(error) { + failure(err); + } + // success + } + }); + ``` + Promise Example; + ```javascript + findAuthor(). + then(findBooksByAuthor). + then(function(books){ + // found books + }).catch(function(reason){ + // something went wrong + }); + ``` + @method then + @param {Function} onFulfilled + @param {Function} onRejected + Useful for tooling. + @return {Promise} + */ + /** + `catch` is simply sugar for `then(undefined, onRejection)` which makes it the same + as the catch block of a try/catch statement. + ```js + function findAuthor(){ + throw new Error('couldn't find that author'); + } + // synchronous + try { + findAuthor(); + } catch(reason) { + // something went wrong + } + // async with promises + findAuthor().catch(function(reason){ + // something went wrong + }); + ``` + @method catch + @param {Function} onRejection + Useful for tooling. + @return {Promise} + */ + + Promise.prototype.catch = function _catch(onRejection) { + return this.then(null, onRejection); + }; + /** + `finally` will be invoked regardless of the promise's fate just as native + try/catch/finally behaves + + Synchronous example: + + ```js + findAuthor() { + if (Math.random() > 0.5) { + throw new Error(); + } + return new Author(); + } + + try { + return findAuthor(); // succeed or fail + } catch(error) { + return findOtherAuther(); + } finally { + // always runs + // doesn't affect the return value + } + ``` + + Asynchronous example: + + ```js + findAuthor().catch(function(reason){ + return findOtherAuther(); + }).finally(function(){ + // author was either found, or not + }); + ``` + + @method finally + @param {Function} callback + @return {Promise} + */ + Promise.prototype.finally = function _finally(callback) { + var promise = this; + var constructor = promise.constructor; + if (isFunction(callback)) { + return promise.then(function (value) { + return constructor.resolve(callback()).then(function () { + return value; + }); + }, function (reason) { + return constructor.resolve(callback()).then(function () { + throw reason; + }); + }); + } + return promise.then(callback, callback); + }; + return Promise; + }(); + Promise$1.prototype.then = then; + Promise$1.all = all; + Promise$1.race = race; + Promise$1.resolve = resolve$1; + Promise$1.reject = reject$1; + Promise$1._setScheduler = setScheduler; + Promise$1._setAsap = setAsap; + Promise$1._asap = asap; + /*global self*/ + function polyfill() { + var local = void 0; + if (typeof global !== 'undefined') { + local = global; + } else if (typeof self !== 'undefined') { + local = self; + } else { + try { + local = Function('return this') (); + } catch (e) { + throw new Error('polyfill failed because global object is unavailable in this environment'); + } + } + var P = local.Promise; + if (P) { + var promiseToString = null; + try { + promiseToString = Object.prototype.toString.call(P.resolve()); + } catch (e) { + // silently ignored + } + if (promiseToString === '[object Promise]' && !P.cast) { + return; + } + } + local.Promise = Promise$1; + } // Strange compat.. + + Promise$1.polyfill = polyfill; + Promise$1.Promise = Promise$1; + return Promise$1; + }); + }).call(this, _dereq_('_process'), typeof global !== 'undefined' ?

All data is + // referenced by a code, which represents one or more values from the + // original input stream. All input bytes can be referenced as the same + // value as an output code. So if you didn't want any compression, you + // could more or less just output the original bytes as codes (there are + // some details to this, but it is the idea). In order to achieve + // compression, values greater then the input range (codes can be up to + // 12-bit while input only 8-bit) represent a sequence of previously seen + // inputs. The decompressor is able to build the same mapping while + // decoding, so there is always a shared common knowledge between the + // encoding and decoder, which is also important for "timing" aspects like + // how to handle variable bit width code encoding. + // + // One obvious but very important consequence of the table system is there + // is always a unique id (at most 12-bits) to map the runs. 'A' might be + // 4, then 'AA' might be 10, 'AAA' 11, 'AAAA' 12, etc. This relationship + // can be used for an effecient lookup strategy for the code mapping. We + // need to know if a run has been seen before, and be able to map that run + // to the output code. Since we start with known unique ids (input bytes), + // and then from those build more unique ids (table entries), we can + // continue this chain (almost like a linked list) to always have small + // integer values that represent the current byte chains in the encoder. + // This means instead of tracking the input bytes (AAAABCD) to know our + // current state, we can track the table entry for AAAABC (it is guaranteed + // to exist by the nature of the algorithm) and the next character D. + // Therefor the tuple of (table_entry, byte) is guaranteed to also be + // unique. This allows us to create a simple lookup key for mapping input + // sequences to codes (table indices) without having to store or search + // any of the code sequences. So if 'AAAA' has a table entry of 12, the + // tuple of ('AAAA', K) for any input byte K will be unique, and can be our + // key.

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". + * + * @property {String} WEBGL + * @final + */ + exports.P2D = P2D; + var WEBGL = 'webgl'; + /** + * One of the two possible values of a WebGL canvas (either WEBGL or WEBGL2), + * which can be used to determine what capabilities the rendering environment + * has. + * @property {String} WEBGL2 + * @final + */ + exports.WEBGL = WEBGL; + var WEBGL2 = 'webgl2'; + // ENVIRONMENT + /** + * @property {String} ARROW + * @final + */ + exports.WEBGL2 = WEBGL2; + var ARROW = 'default'; + /** + * @property {String} CROSS + * @final + */ + exports.ARROW = ARROW; + var CROSS = 'crosshair'; + /** + * @property {String} HAND + * @final + */ + exports.CROSS = CROSS; + var HAND = 'pointer'; + /** + * @property {String} MOVE + * @final + */ + exports.HAND = HAND; + var MOVE = 'move'; + /** + * @property {String} TEXT + * @final + */ + exports.MOVE = MOVE; + var TEXT = 'text'; + /** + * @property {String} WAIT + * @final + */ + exports.TEXT = TEXT; + var WAIT = 'wait'; + // TRIGONOMETRY + /** + * A `Number` constant that's approximately 1.5708. + * + * `HALF_PI` is half the value of the mathematical constant π.

Red values with red values, greens with greens, and blues with + * blues. + * + * The parameter, `mode`, sets the blend mode. For example, calling + * `blendMode(ADD)` sets the blend mode to `ADD`. The following blend modes + * are available in both 2D and WebGL mode: + * + * - `BLEND`: color values from the source overwrite the canvas. This is the default mode. + * - `ADD`: color values from the source are added to values from the canvas. + * - `DARKEST`: keeps the darkest color value. + * - `LIGHTEST`: keeps the lightest color value. + * - `EXCLUSION`: similar to `DIFFERENCE` but with less contrast. + * - `MULTIPLY`: color values from the source are multiplied with values from the canvas. The result is always darker. + * - `SCREEN`: all color values are inverted, then multiplied, then inverted again. The result is always lighter. (Opposite of `MULTIPLY`) + * - `REPLACE`: the last source drawn completely replaces the rest of the canvas. + * - `REMOVE`: overlapping pixels are removed by making them completely transparent. + * + * The following blend modes are only available in 2D mode: + * + * - `DIFFERENCE`: color values from the source are subtracted from the values from the canvas. If the difference is a negative number, it's made positive. + * - `OVERLAY`: combines `MULTIPLY` and `SCREEN`. Dark values in the canvas get darker and light values get lighter. + * - `HARD_LIGHT`: combines `MULTIPLY` and `SCREEN`. Dark values in the source get darker and light values get lighter. + * - `SOFT_LIGHT`: a softer version of `HARD_LIGHT`. + * - `DODGE`: lightens light tones and increases contrast. Divides the canvas color values by the inverted color values from the source. + * - `BURN`: darkens dark tones and increases contrast. Divides the source color values by the inverted color values from the canvas, then inverts the result. + * + * The following blend modes are only available in WebGL mode: + * + * - `SUBTRACT`: RGB values from the source are subtracted from the values from the canvas. If the difference is a negative number, it's made positive. Alpha (transparency) values from the source and canvas are added. + * + * @method blendMode + * @param {Constant} mode blend mode to set. + * either BLEND, DARKEST, LIGHTEST, DIFFERENCE, MULTIPLY, + * EXCLUSION, SCREEN, REPLACE, OVERLAY, HARD_LIGHT, + * SOFT_LIGHT, DODGE, BURN, ADD, REMOVE or SUBTRACT + * + * @example + *

Put another way, all + * p5.js sketches are objects with methods including `pInst.setup()`, + * `pInst.draw()`, `pInst.circle()`, and `pInst.fill()`. By default, sketches + * run in "global mode" to hide some of this complexity. + * + * In global mode, a default instance of the `p5` class is created + * automatically. The default `p5` instance searches the web page's source + * code for declarations of system functions such as `setup()`, `draw()`, + * and `mousePressed()`, then attaches those functions to itself as methods. + * Calling a function such as `circle()` in global mode actually calls the + * default `p5` object's `pInst.circle()` method. + * + * It's often helpful to isolate the code within sketches from the rest of the + * code on a web page. Two common use cases are web pages that use other + * JavaScript libraries and web pages with multiple sketches. "Instance mode" + * makes it easy to support both of these scenarios. + * + * Instance mode sketches support the same API as global mode sketches. They + * use a function to bundle, or encapsulate, an entire sketch. The function + * containing the sketch is then passed to the `p5()` constructor. + * + * The first parameter, `sketch`, is a function that contains the sketch. For + * example, the statement `new p5(mySketch)` would create a new instance mode + * sketch from a function named `mySketch`. The function should have one + * parameter, `p`, that's a `p5` object. + * + * The second parameter, `node`, is optional. If a string is passed, as in + * `new p5(mySketch, 'sketch-one')` the new instance mode sketch will become a + * child of the HTML element with the id `sketch-one`. If an HTML element is + * passed, as in `new p5(mySketch, myElement)`, then the new instance mode + * sketch will become a child of the `Element` object called `myElement`. + * + * @method p5 + * @param {Object} sketch function containing the sketch. + * @param {String|HTMLElement} node ID or reference to the HTML element that will contain the sketch. + * + * @example + *

By + * default, the grid will run through the origin `(0, 0, 0)` of the sketch + * along the XZ plane. `debugMode()` also adds an axes icon that points along + * the positive x-, y-, and z-axes. Calling `debugMode()` displays the grid + * and axes icon with their default size and position. + * + * There are four ways to call `debugMode()` with optional parameters to + * customize the debugging environment. + * + * The first way to call `debugMode()` has one parameter, `mode`. If the + * system constant `GRID` is passed, as in `debugMode(GRID)`, then the grid + * will be displayed and the axes icon will be hidden. If the constant `AXES` + * is passed, as in `debugMode(AXES)`, then the axes icon will be displayed + * and the grid will be hidden. + * + * The second way to call `debugMode()` has six parameters. The first + * parameter, `mode`, selects either `GRID` or `AXES` to be displayed. The + * next five parameters, `gridSize`, `gridDivisions`, `xOff`, `yOff`, and + * `zOff` are optional. They’re numbers that set the appearance of the grid + * (`gridSize` and `gridDivisions`) and the placement of the axes icon + * (`xOff`, `yOff`, and `zOff`). For example, calling + * `debugMode(20, 5, 10, 10, 10)` sets the `gridSize` to 20 pixels, the number + * of `gridDivisions` to 5, and offsets the axes icon by 10 pixels along the + * x-, y-, and z-axes. + * + * The third way to call `debugMode()` has five parameters. The first + * parameter, `mode`, selects either `GRID` or `AXES` to be displayed. The + * next four parameters, `axesSize`, `xOff`, `yOff`, and `zOff` are optional. + * They’re numbers that set the appearance of the size of the axes icon + * (`axesSize`) and its placement (`xOff`, `yOff`, and `zOff`). + * + * The fourth way to call `debugMode()` has nine optional parameters. The + * first five parameters, `gridSize`, `gridDivisions`, `gridXOff`, `gridYOff`, + * and `gridZOff` are numbers that set the appearance of the grid. For + * example, calling `debugMode(100, 5, 0, 0, 0)` sets the `gridSize` to 100, + * the number of `gridDivisions` to 5, and sets all the offsets to 0 so that + * the grid is centered at the origin. The next four parameters, `axesSize`, + * `xOff`, `yOff`, and `zOff` are numbers that set the appearance of the size + * of the axes icon (`axesSize`) and its placement (`axesXOff`, `axesYOff`, + * and `axesZOff`). For example, calling + * `debugMode(100, 5, 0, 0, 0, 50, 10, 10, 10)` sets the `gridSize` to 100, + * the number of `gridDivisions` to 5, and sets all the offsets to 0 so that + * the grid is centered at the origin. It then sets the `axesSize` to 50 and + * offsets the icon 10 pixels along each axis. + * + * @method debugMode + * + * @example + *

Once the model is + * loaded, it can be displayed with the + * model() function, as in `model(shape)`. + * + * There are three ways to call `loadModel()` with optional parameters to help + * process the model. + * + * The first parameter, `path`, is always a `String` with the path to the + * file. Paths to local files should be relative, as in + * `loadModel('assets/model.obj')`. URLs such as + * `'https://example.com/model.obj'` may be blocked due to browser security. + * + * The first way to call `loadModel()` has three optional parameters after the + * file path. The first optional parameter, `successCallback`, is a function + * to call once the model loads. For example, + * `loadModel('assets/model.obj', handleModel)` will call the `handleModel()` + * function once the model loads. The second optional parameter, + * `failureCallback`, is a function to call if the model fails to load. For + * example, `loadModel('assets/model.obj', handleModel, handleFailure)` will + * call the `handleFailure()` function if an error occurs while loading. The + * third optional parameter, `fileType`, is the model’s file extension as a + * string. For example, + * `loadModel('assets/model', handleModel, handleFailure, '.obj')` will try to + * load the file model as a `.obj` file. + * + * The second way to call `loadModel()` has four optional parameters after the + * file path. The first optional parameter is a `Boolean` value. If `true` is + * passed, as in `loadModel('assets/model.obj', true)`, then the model will be + * resized to ensure it fits the canvas. The next three parameters are + * `successCallback`, `failureCallback`, and `fileType` as described above. + * + * The third way to call `loadModel()` has one optional parameter after the + * file path. The optional parameter, `options`, is an `Object` with options, + * as in `loadModel('assets/model.obj', options)`. The `options` object can + * have the following properties: + * + * + * let options = { + * // Enables standardized size scaling during loading if set to true. + * normalize: true, + * + * // Function to call once the model loads. + * successCallback: handleModel, + * + * // Function to call if an error occurs while loading. + * failureCallback: handleError, + * + * // Model's file extension. + * fileType: '.stl', + * + * // Flips the U texture coordinates of the model. + * flipU: false, + * + * // Flips the V texture coordinates of the model. + * flipV: false + * }; + * + * // Pass the options object to loadModel(). + * loadModel('assets/model.obj', options); + * + * + * Models can take time to load. Calling `loadModel()` in + * preload() ensures models load before they're + * used in setup() or draw(). + * + * Note: There’s no support for colored STL files. STL files with color will + * be rendered without color. + * + * @method loadModel + * @param {String} path path of the model to be loaded. + * @param {Boolean} normalize if `true`, scale the model to fit the canvas. + * @param {function(p5.Geometry)} [successCallback] function to call once the model is loaded.

Built-in + * shapes such as rect() and + * box() already have these texture mappings based on + * their vertices. Custom shapes created with + * vertex() require texture mappings to be passed as + * uv coordinates. + * + * Each call to vertex() must include 5 arguments, + * as in `vertex(x, y, z, u, v)`, to map the vertex at coordinates `(x, y, z)` + * to the pixel at coordinates `(u, v)` within an image.

Doing so can produce interesting visual effects such as tiling. + * For example, the custom shape above could have u-coordinates are greater + * than the image’s width: + * + * + * // Apply the image as a texture. + * texture(img); + * + * // Draw the rectangle. + * beginShape(); + * vertex(0, 0, 0, 0, 0); + * + * // Top-right. + * // u: 600 + * vertex(30, 0, 0, 600, 0); + * + * // Bottom-right. + * // u: 600 + * vertex(30, 50, 0, 600, 500); + * + * vertex(0, 50, 0, 0, 500); + * endShape(); + * + * + * The u-coordinates of 600 are greater than the texture image’s width of 300. + * This creates interesting possibilities. + * + * The first parameter, `wrapX`, accepts three possible constants. If `CLAMP` + * is passed, as in `textureWrap(CLAMP)`, the pixels at the edge of the + * texture will extend to the shape’s edges. If `REPEAT` is passed, as in + * `textureWrap(REPEAT)`, the texture will tile repeatedly until reaching the + * shape’s edges. If `MIRROR` is passed, as in `textureWrap(MIRROR)`, the + * texture will tile repeatedly until reaching the shape’s edges, flipping + * its orientation between tiles.

        + */ + //////////////////////////////////////////////////////////////////////////////// + // Camera Projection Methods + //////////////////////////////////////////////////////////////////////////////// + /** + * Sets a perspective projection for the camera. + * + * In a perspective projection, shapes that are further from the camera appear + * smaller than shapes that are near the camera. This technique, called + * foreshortening, creates realistic 3D scenes. It’s applied by default in new + * `p5.Camera` objects. + * + * `myCamera.perspective()` changes the camera’s perspective by changing its + * viewing frustum. The frustum is the volume of space that’s visible to the + * camera. The frustum’s shape is a pyramid with its top cut off. The camera + * is placed where the top of the pyramid should be and points towards the + * base of the pyramid. It views everything within the frustum. + * + * The first parameter, `fovy`, is the camera’s vertical field of view. It’s + * an angle that describes how tall or narrow a view the camera has. For + * example, calling `myCamera.perspective(0.5)` sets the camera’s vertical + * field of view to 0.5 radians. By default, `fovy` is calculated based on the + * sketch’s height and the camera’s default z-coordinate, which is 800. The + * formula for the default `fovy` is `2 * atan(height / 2 / 800)`. + * + * The second parameter, `aspect`, is the camera’s aspect ratio. It’s a number + * that describes the ratio of the top plane’s width to its height. For + * example, calling `myCamera.perspective(0.5, 1.5)` sets the camera’s field + * of view to 0.5 radians and aspect ratio to 1.5, which would make shapes + * appear thinner on a square canvas. By default, `aspect` is set to + * `width / height`. + * + * The third parameter, `near`, is the distance from the camera to the near + * plane. For example, calling `myCamera.perspective(0.5, 1.5, 100)` sets the + * camera’s field of view to 0.5 radians, its aspect ratio to 1.5, and places + * the near plane 100 pixels from the camera. Any shapes drawn less than 100 + * pixels from the camera won’t be visible. By default, `near` is set to + * `0.1 * 800`, which is 1/10th the default distance between the camera and + * the origin. + * + * The fourth parameter, `far`, is the distance from the camera to the far + * plane. For example, calling `myCamera.perspective(0.5, 1.5, 100, 10000)` + * sets the camera’s field of view to 0.5 radians, its aspect ratio to 1.5, + * places the near plane 100 pixels from the camera, and places the far plane + * 10,000 pixels from the camera. Any shapes drawn more than 10,000 pixels + * from the camera won’t be visible. By default, `far` is set to `10 * 800`, + * which is 10 times the default distance between the camera and the origin. + * + * @method perspective + * @for p5.Camera + * @param {Number} [fovy] camera frustum vertical field of view. Defaults to + * `2 * atan(height / 2 / 800)`. + * @param {Number} [aspect] camera frustum aspect ratio.
