Opengl uniform functions
WebIf you are using modern OpenGL, you can use Uniform Buffer Objects, which have been available since OpenGL 3.1. However, there is a little more involved "setup" required. Specifically, they require that you author your shaders in a particular way (defining the uniform blocks). WebIt is legal to have the same uniform defined in different shader stages.
