This section will not cover the entire language in detail; the GLSL specification can handle that.

WebThis function takes the handle to the shader program object and the name of the uniform variable, and returns its location. If the uniform variable is not an active uniform variable, the function returns -1. We then assign a value to the uniform variable using glUniformMatrix4fv.
