The WebGLRenderingContext.createProgram()
method of the WebGL API creates and initializes a WebGLProgram
object.
None.
Return valueA 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.
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.
