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 - *

The - * simplest use requires only three parameters: img, x, and y—where (x, y) is - * the position of the image. Two more parameters can optionally be added to - * specify the width and height of the image. - * - * This function can also be used with eight Number parameters. To - * differentiate between all these parameters, p5.js uses the language of - * "destination rectangle" (which corresponds to "dx", "dy", etc.) and "source - * image" (which corresponds to "sx", "sy", etc.) below. Specifying the - * "source image" dimensions can be useful when you want to display a - * subsection of the source image instead of the whole thing. Here's a diagram - * to explain further: - *

- * - * This function can also be used to draw images without distorting the orginal aspect ratio, - * by adding 9th parameter, fit, which can either be COVER or CONTAIN. - * CONTAIN, as the name suggests, contains the whole image within the specified destination box - * without distorting the image ratio. - * COVER covers the entire destination box. - * - * - * - * @method image - * @param {p5.Image|p5.Element|p5.Texture} img the image to display - * @param {Number} x the x-coordinate of the top-left corner of the image - * @param {Number} y the y-coordinate of the top-left corner of the image - * @param {Number} [width] the width to draw the image - * @param {Number} [height] the height to draw the image - * @example - *

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 dimensions 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). As a general rule the smaller the difference between coordinates, - * the smoother the resulting noise sequence will be. Steps of 0.005-0.03 - * work best for most applications, but this will differ depending on use. - * - * @method noise - * @param {Number} x x-coordinate in noise space - * @param {Number} [y] y-coordinate in noise space - * @param {Number} [z] z-coordinate in noise space - * @return {Number} Perlin noise value (between 0 and 1) at specified - * coordinates - * @example - *
