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