Texture

Extends:

CgTexture → Texture

A Texture

Example:

// generate a 256x256 pixel texture of random colors
const size=256;
const data = new Uint8Array(size*size*4);

for(var x=0;x<size*size*4;x++) data[ x*4+3]=255;

const tex=new CGL.Texture(cgl);
tex.initFromData(data,size,size,CGL.Texture.FILTER_NEAREST,CGL.Texture.WRAP_REPEAT);
