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.
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
WebGLShader
s 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 `Could not compile WebGL program. \n\n${info}`;
}
See WebGLShader
for information on creating the
vertexShader
and fragmentShader
in the above example.
