Static p5_sys::global::textureMode[][src]

pub static textureMode: TextureModeInternalType
Expand description

Sets the coordinate space for texture mapping. The default mode is IMAGE which refers to the actual coordinates of the image. NORMAL refers to a normalized space of values ranging from 0 to 1. This function only works in WEBGL mode.

With IMAGE, if an image is 100 x 200 pixels, mapping the image onto the entire size of a quad would require the points (0,0) (100, 0) (100,200) (0,200). The same mapping in NORMAL is (0,0) (1,0) (1,1) (0,1).

Examples

let img;

function preload() {
  img = loadImage('assets/laDefense.jpg');
}

function setup() {
  createCanvas(100, 100, WEBGL);
}

function draw() {
  texture(img);
  textureMode(NORMAL);
  beginShape();
  vertex(-50, -50, 0, 0);
  vertex(50, -50, 1, 0);
  vertex(50, 50, 1, 1);
  vertex(-50, 50, 0, 1);
  endShape();
}

Parameters

mode either IMAGE or NORMAL
