replaceShaderProgram

Returns a shader program from the cache, or creates and caches a new shader program, given the GLSL vertex and fragment shader source and attribute locations.

The difference between this and ShaderCache#getShaderProgram, is this is used to replace an existing reference to a shader program, which is passed as the first argument.

Parameters:

Name	Type	Description
shaderProgram	ShaderProgram	The shader program that is being reassigned. This can be undefined.
vertexShaderSource	String	The GLSL source for the vertex shader.
fragmentShaderSource	String	The GLSL source for the fragment shader.
attributeLocations	Object	Indices for the attribute inputs to the vertex shader.

Returns:

ShaderProgram The cached or newly created shader program.

Example

this._shaderProgram = context.getShaderCache().replaceShaderProgram(
    this._shaderProgram, vs, fs, attributeLocations);
