* 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;

* Creates a new p5.Image. A p5.Image is a canvas backed representation of an
* image.
*
* p5 can display .gif, .jpg and .png images. Images may be displayed
* in 2D and 3D space. Before an image is used, it must be loaded with the
* loadImage() function. The p5.Image class contains fields for the width and
* height of the image, as well as an array called pixels[] that contains the
* values for every pixel in the image.
*
* The methods described below allow easy access to the image's pixels and
* alpha channel and simplify the process of compositing.
*
* Before using the pixels[] array, be sure to use the loadPixels() method on
* the image to make sure that the pixel data is properly loaded.
* @example
*
* let img;
* function preload() {
* img = loadImage('assets/bricks.jpg');
* }
* function setup() {
* imageMode(CENTER);
* image(img, 50, 50, 80, 80);
* }
*
*
* function setup() {
* let img = createImage(100, 100); // same as new p5.Image(100, 100);
* img.loadPixels();
* createCanvas(100, 100);
* background(0);
*
* // helper for writing color to array
* function writeColor(image, x, y, red, green, blue, alpha) {
* let index = (x + y * width) * 4;
* image.pixels[index] = red;
* image.pixels[index + 1] = green;
* image.pixels[index + 2] = blue;
* image.pixels[index + 3] = alpha;
* }
*
* let x, y;
* // fill with random colors
* for (y = 0; y < img.height; y++) {
* for (x = 0; x < img.width; x++) {
* let red = random(255);
* let green = random(255);
* let blue = random(255);
* let alpha = 255;
* writeColor(img, x, y, red, green, blue, alpha);
* }
* }
*
* // draw a red line
* y = 0;
* for (x = 0; x < img.width; x++) {
* writeColor(img, x, y, 255, 0, 0, 255);
* }
*
* // draw a green line
* y = img.height - 1;
* for (x = 0; x < img.width; x++) {

* The element can be one of p5.Element,an Array of

* **Note that it is not recommended to

* @param {String} [filename] If an object is provided as the first
* parameter, then the second parameter
* indicates the filename,
* and should include an appropriate
* file extension (see examples above).

* 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). 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 *

/**
* 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.
