WebGLRenderingContext: createProgram() method
Baseline
Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
Note: This feature is available in Web Workers.
The WebGLRenderingContext.createProgram() method of the
WebGL API creates and initializes a
WebGLProgram object.
Syntax
js
createProgram()
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.
