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.
