Each color stores the color mode and level maxes that applied at the\ntime of its construction. These are used to interpret the input arguments\n(at construction and later for that instance of color) and to format the\noutput e.g. when saturation() is requested.

\n

Internally we store an array representing the ideal RGBA values in floating\npoint form, normalized from 0 to 1. From this we calculate the closest\nscreen color (RGBA levels from 0 to 255) and expose this to the renderer.

\n

We also cache normalized, floating point components of the color in various\nrepresentations as they are calculated. This is done to prevent repeating a\nconversion that has already been performed.

\nIn many of the p5.js examples, you will see p5.Vector used to describe a\nposition, velocity, or acceleration. For example, if you consider a rectangle\nmoving across the screen, at any given instant it has a position (a vector\nthat points from the origin to its location), a velocity (the rate at which\nthe object's position changes per time unit, expressed as a vector), and\nacceleration (the rate at which the object's velocity changes per time\nunit, expressed as a vector).\n

New p5.Camera objects can be made through the\ncreateCamera() function and controlled through\nthe methods described below.

It is possible\nto create multiple cameras, in which case the current camera\ncan be set through the setCamera() method.

\n

Note:\nThe methods below operate in two coordinate systems: the 'world' coordinate\nsystem describe positions in terms of their relationship to the origin along\nthe X, Y and Z axes whereas the camera's 'local' coordinate system\ndescribes positions from the camera's point of view: left-right, up-down,\nand forward-backward.

FFT (Fast Fourier Transform) is an analysis algorithm that\nisolates individual\n\naudio frequencies within a waveform.

\n\n

Once instantiated, a p5.FFT object can return an array based on\ntwo types of analyses:
• FFT.waveform() computes\namplitude values along the time domain. The array indices correspond\nto samples across a brief moment in time. Each value represents\namplitude of the waveform at that sample of time.
\n• FFT.analyze() computes amplitude values along the\nfrequency domain. The array indices correspond to frequencies (i.e.\npitches), from the lowest to the highest that humans can hear. Each\nvalue represents amplitude at that slice of the frequency spectrum.\nUse with getEnergy() to measure amplitude at specific\nfrequencies, or within a range of frequencies.

\n\n

FFT analyzes a very short snapshot of sound called a sample\nbuffer. It returns an array of amplitude measurements, referred\nto as bins. The array is 1024 bins long by default.\nYou can change the bin array length, but it must be a power of 2\nbetween 16 and 1024 in order for the FFT algorithm to function\ncorrectly.

Compressor is an audio effect class that performs dynamics compression\non an audio input source. This is a very commonly used technique in music\nand sound production. Compression creates an overall louder, richer, \nand fuller sound by lowering the volume of louds and raising that of softs.\nCompression can be used to avoid clipping (sound distortion due to \npeaks in volume) and is especially useful when many sounds are played \nat once. Compression can be used on indivudal sound sources in addition\nto the master output.

PeakDetect works in conjunction with p5.FFT to\nlook for onsets in some or all of the frequency spectrum.\n

\n

\nTo use p5.PeakDetect, call update in the draw loop\nand pass in a p5.FFT object.\n

\n

\nYou can listen for a specific part of the frequency spectrum by\nsetting the range between freq1 and freq2.\n

\n\n

threshold is the threshold for detecting a peak,\nscaled between 0 and 1. It is logarithmic, so 0.1 is half as loud\nas 1.0.

\n\n

\nThe update method is meant to be run in the draw loop, and\nframes determines how many loops must pass before\nanother peak can be detected.\nFor example, if the frameRate() = 60, you could detect the beat of a\n120 beat-per-minute song with this equation:\n framesPerPeak = 60 / (estimatedBPM / 60 );\n

\nBased on example contribtued by @b2renger, and a simple beat detection\nexplanation by Felix Turner.\n

This function does 3 things:

\n
    \n

  1. Bounds the desired start/stop angles for an arc (in radians) so that:

    \n
    0 <= start < TWO_PI ;    start <= stop < start + TWO_PI\n

    This means that the arc rendering functions don't have to be concerned\nwith what happens if stop is smaller than start, or if the arc 'goes\nround more than once', etc.: they can just start at start and increase\nuntil stop and the correct arc will be drawn.

    \n
    2. \n

  2. Optionally adjusts the angles within each quadrant to counter the naive\nscaling of the underlying ellipse up from the unit circle. Without\nthis, the angles become arbitrary when width != height: 45 degrees\nmight be drawn at 5 degrees on a 'wide' ellipse, or at 85 degrees on\na 'tall' ellipse.

    \n
    3. \n

  3. Flags up when start and stop correspond to the same place on the\nunderlying ellipse. This is useful if you want to do something special\nthere (like rendering a whole ellipse instead).

Draws a square to the screen.

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.\n

\nIt 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.\n

This function can be used with different numbers of parameters. The\nsimplest use requires only three parameters: img, x, and y—where (x, y) is\nthe position of the image. Two more parameters can optionally be added to\nspecify the width and height of the image.

\n

This function can also be used with all eight Number parameters. To\ndifferentiate between all these parameters, p5.js uses the language of\n"destination rectangle" (which corresponds to "dx", "dy", etc.) and "source\nimage" (which corresponds to "sx", "sy", etc.) below. Specifying the\n"source image" dimensions can be useful when you want to display a\nsubsection of the source image instead of the whole thing. Here's a diagram\nto explain further:\n

Uint8ClampedArray\ncontaining the values for all the pixels in the display window.\nThese values are numbers. This array is the size (include an appropriate\nfactor for pixelDensity) of the display window x4,\nrepresenting the R, G, B, A values in order for each pixel, moving from\nleft to right across each row, then down each column. Retina and other\nhigh density displays will have more pixels[] (by a factor of\npixelDensity^2).\nFor example, if the image is 100x100 pixels, there will be 40,000. On a\nretina display, there will be 160,000.\n

\nThe first four values (indices 0-3) in the array will be the R, G, B, A\nvalues of the pixel at (0, 0). The second four values (indices 4-7) will\ncontain the R, G, B, A values of the pixel at (1, 0). More generally, to\nset values for a pixel at (x, y):

While the above method is complex, it is flexible enough to work with\nany pixelDensity. Note that set() will automatically take care of\nsetting all the appropriate values in pixels[] for a given (x, y) at\nany pixelDensity, but the performance may not be as fast when lots of\nmodifications are made to the pixel array.\n

\nBefore accessing this array, the data must loaded with the loadPixels()\nfunction. After the array data has been modified, the updatePixels()\nfunction must be run to update the changes.\n

Possible options include:\n

    \n
  • csv - parse the table as comma-separated values

  • tsv - parse the table as tab-separated values
    • \n
  • header - this table has a header (title) row

The default behavior is to save the canvas as an image. You can\noptionally specify a filename.\nFor example:

\n 
\n save();\n save('myCanvas.jpg'); // save a specific canvas with a filename\n

Alternately, the first parameter can be a pointer to a canvas\np5.Element, an Array of Strings,\nan Array of JSON, a JSON object, a p5.Table, a p5.Image, or a\np5.SoundFile (requires p5.sound). The second parameter is a filename\n(including extension). The third parameter is for options specific\nto this type of object. This method will save a file that fits the\ngiven parameters. For example:

\n\n 
\n // Saves canvas as an image\n save('myCanvas.jpg');\n\n // Saves pImage as a png image\n let img = createImage(10, 10);\n save(img, 'my.png');\n\n // Saves canvas as an image\n let cnv = createCanvas(100, 100);\n save(cnv, 'myCanvas.jpg');\n\n // Saves p5.Renderer object as an image\n let gb = createGraphics(100, 100);\n save(gb, 'myGraphics.jpg');\n\n let myTable = new p5.Table();\n\n // Saves table as html file\n save(myTable, 'myTable.html');\n\n // Comma Separated Values\n save(myTable, 'myTable.csv');\n\n // Tab Separated Values\n save(myTable, 'myTable.tsv');\n\n let myJSON = { a: 1, b: true };\n\n // Saves pretty JSON\n save(myJSON, 'my.json');\n\n // Optimizes JSON filesize\n save(myJSON, 'my.json', true);\n\n // Saves array of strings to a text file with line breaks after each item\n let arrayOfStrings = ['a', 'b'];\n save(arrayOfStrings, 'my.txt');\n

Table Options

\n

Generic class for handling tabular data, typically from a\nCSV, TSV, or other sort of spreadsheet file.

\n

CSV files are\n\ncomma separated values, often with the data in quotes. TSV\nfiles use tabs as separators, and usually don't bother with the\nquotes.

\n

File names should end with .csv if they're comma separated.

\n

A rough "spec" for CSV can be found\nhere.

\n

To load files, use the loadTable method.

\n

To save tables to your computer, use the save method\n or the saveTable method.

\n\n

Possible options include:

\n
    \n
  • csv - parse the table as comma-separated values\n
  • tsv - parse the table as tab-separated values\n
  • header - this table has a header (title) row\n

Returns the Perlin noise value at specified coordinates. Perlin noise is\na random sequence generator producing a more natural ordered, harmonic\nsuccession of numbers compared to the standard random() function.\nIt was invented by Ken Perlin in the 1980s and been used since in\ngraphical applications to produce procedural textures, natural motion,\nshapes, terrains etc.

The main difference to the\nrandom() function is that Perlin noise is defined in an infinite\nn-dimensional space where each pair of coordinates corresponds to a\nfixed semi-random value (fixed only for the lifespan of the program; see\nthe noiseSeed() function). p5.js can compute 1D, 2D and 3D noise,\ndepending on the number of coordinates given. The resulting value will\nalways be between 0.0 and 1.0. The noise value can be animated by moving\nthrough the noise space as demonstrated in the example above. The 2nd\nand 3rd dimension can also be interpreted as time.

The actual\nnoise is structured similar to an audio signal, in respect to the\nfunction's use of frequencies. Similar to the concept of harmonics in\nphysics, perlin noise is computed over several octaves which are added\ntogether for the final result.

Another way to adjust the\ncharacter of the resulting sequence is the scale of the input\ncoordinates. As the function works within an infinite space the value of\nthe coordinates doesn't matter as such, only the distance between\nsuccessive coordinates does (eg. when using noise() within a\nloop). As a general rule the smaller the difference between coordinates,\nthe smoother the resulting noise sequence will be. Steps of 0.005-0.03\nwork best for most applications, but this will differ depending on use.

Adjusts the character and level of detail produced by the Perlin noise\n function. Similar to harmonics in physics, noise is computed over\n several octaves. Lower octaves contribute more to the output signal and\n as such define the overall intensity of the noise, whereas higher octaves\n create finer grained details in the noise sequence.\n

\n By default, noise is computed over 4 octaves with each octave contributing\n exactly half than its predecessor, starting at 50% strength for the 1st\n octave. This falloff amount can be changed by adding an additional function\n parameter. Eg. a falloff factor of 0.75 means each octave will now have\n 75% impact (25% less) of the previous lower octave. Any value between\n 0.0 and 1.0 is valid, however note that values greater than 0.5 might\n result in greater than 1.0 values returned by noise().\n

\n By changing these parameters, the signal created by the noise()\n function can be adapted to fit very specific needs and characteristics.

debugMode() helps visualize 3D space by adding a grid to indicate where the\n‘ground’ is in a sketch and an axes icon which indicates the +X, +Y, and +Z\ndirections. This function can be called without parameters to create a\ndefault grid and axes icon, or it can be called according to the examples\nabove to customize the size and position of the grid and/or axes icon. The\ngrid is drawn using the most recently set stroke color and weight. To\nspecify these parameters, add a call to stroke() and strokeWeight()\njust before the end of the draw() loop.

\n

By default, the grid will run through the origin (0,0,0) of the sketch\nalong the XZ plane\nand the axes icon will be offset from the origin. Both the grid and axes\nicon will be sized according to the current canvas size. Note that because the\ngrid runs parallel to the default camera view, it is often helpful to use\ndebugMode along with orbitControl to allow full view of the grid.

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

\nOne of the limitations of the OBJ and STL format is that it doesn't have a built-in\nsense of scale. This means that models exported from different programs might\nbe very different sizes. If your model isn't displaying, try calling\nloadModel() with the normalized parameter set to true. This will resize the\nmodel to a scale appropriate for p5. You can also make additional changes to\nthe final size of your model with the scale() function.

Generic class for handling tabular data, typically from a\nCSV, TSV, or other sort of spreadsheet file.

\n

CSV files are\n\ncomma separated values, often with the data in quotes. TSV\nfiles use tabs as separators, and usually don\'t bother with the\nquotes.

\n

File names should end with .csv if they\'re comma separated.

\n

A rough "spec" for CSV can be found\nhere.

\n

To load files, use the loadTable method.

\n

To save tables to your computer, use the save method\n or the saveTable method.

\n\nPossible options include:\n
    \n
  • csv - parse the table as comma-separated values\n
  • tsv - parse the table as tab-separated values\n
  • header - this table has a header (title) row\n

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' + ?

Save an image, text, json, csv, wav, or html. Prompts download to + * the client's computer. Note that it is not recommended to call save() + * within draw if it's looping, as the save() function will open a new save + * dialog every frame.

+ *

The default behavior is to save the canvas as an image. You can + * optionally specify a filename. + * For example:

+ * 

+           * save();
+           * save('myCanvas.jpg'); // save a specific canvas with a filename
+           *
+ * + *

Alternately, the first parameter can be a pointer to a canvas + * p5.Element, an Array of Strings, + * an Array of JSON, a JSON object, a p5.Table, a p5.Image, or a + * p5.SoundFile (requires p5.sound). The second parameter is a filename + * (including extension). The third parameter is for options specific + * to this type of object. This method will save a file that fits the + * given parameters. For example:

+ * + * 

+           * // Saves canvas as an image
+           * save('myCanvas.jpg');
+           *

+           * save(cnv, 'myCanvas.jpg');
+           *
+           * // Saves p5.Renderer object as an image

CSV files are + * + * comma separated values, often with the data in quotes. TSV + * files use tabs as separators, and usually don't bother with the + * quotes.

  • tsv - parse the table as tab-separated values + *

The main difference to the + * random() function is that Perlin noise is defined in an infinite + * n-dimensional space where each pair of coordinates corresponds to a + * fixed semi-random value (fixed only for the lifespan of the program; see + * the noiseSeed() function). p5.js can compute 1D, 2D and 3D noise, + * depending on the number of coordinates given. The resulting value will + * always be between 0.0 and 1.0. The noise value can be animated by moving + * through the noise space as demonstrated in the example above. The 2nd + * and 3rd dimension can also be interpreted as time.

The actual + * noise is structured similar to an audio signal, in respect to the + * function's use of frequencies. Similar to the concept of harmonics in + * physics, perlin noise is computed over several octaves which are added + * together for the final result.

Another way to adjust the + * character of the resulting sequence is the scale of the input + * coordinates. As the function works within an infinite space the value of + * the coordinates doesn't matter as such, only the distance between + * successive coordinates does (eg. when using noise() within a + * loop).
