WebGLRenderingContext.createProgram()

The WebGLRenderingContext.createProgram() method of the WebGL API creates and initializes a WebGLProgram object.

Syntax

WebGLProgram gl.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

var 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) ) {
  var 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.
