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. The first argument is the uniform variable's location. WebNormally, most of the Per-Sample Processing steps happen after the fragment shader. However, with OpenGL 4.2 or ARB_shader_image_load_store, the shader can enforce Early Fragment Testing, which ensures that the conditional per-sample tests that discard fragments happen before the fragment shader executes. high school kids bullying
