WebGLRenderingContext.attachShader()

The WebGLRenderingContext.attachShader() method of the WebGL API attaches either a fragment or vertex WebGLShader to a WebGLProgram.

Syntax

void gl.attachShader(program, shader);

Parameters

program

A WebGLProgram.

shader

A fragment or vertex WebGLShader.

Examples

The following code attaches pre-existing shaders to a WebGLProgram.

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;
}
