WebGLRenderingContext: createProgram() method - Web APIs | MDN
Syntax
Parameters
None.
Return value
A WebGLProgram object that is a combination of two compiled
WebGLShaders consisting of a vertex shader and a fragment shader (both
written in GLSL). These are then linked into a usable program.
Examples
Creating a WebGL program
js
const program = gl.createProgram();
// Attach pre-existing shaders
gl.attachShader(program, vertexShader);
gl.attachShader(program, fragmentShader);
gl.linkProgram(program);
if (!gl.getProgramParameter(program, gl.LINK_STATUS)) {
const info = gl.getProgramInfoLog(program);
throw new Error(`Could not compile WebGL program. \n\n${info}`);
}
See WebGLShader for information on creating the
vertexShader and fragmentShader in the above example.
