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
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
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.
