Opengl layout position
WebOpenGL internally stores a reference to the buffer per target and, based on the target, processes the buffer differently. So far we've been filling the buffer's memory by calling glBufferData, which allocates a piece of GPU memory and adds data into this memory. If we were to pass NULL as its data argument, the function would only allocate ... Uniforms defined outside of Interface Blockshave a location. This location can be directly assigned in the shader, using this syntax: Calling glGetUniformLocation(prog, "modelToWorldMatrix") is guaranteed to return 2.

For example, the (x, y) location (0.5, 0.5) is returned for the lower-left-most pixel in a window. The origin of gl_FragCoord may be changed by redeclaring gl_FragCoord with the origin_upper_left identifier.
WebI have done some digging and people say the it is a bad idea to try and abstract OpenGL into classes. So, I want information on how I should format my code so that it is easy to use and build on. Encase this is useful, I want in the future to be able to make simple 2D and 3D games as well as be able to use OpenGL for other random projects of mine.
