I can't seem to have a grasp on OpenGL VAOs and VBOs.

I am coding an OBJ Loader from scratch (BTW I am using LWJGL) and I can't seem to get the order of normals correctly. When I look at the OBJ File I notice that there are positions with different normals and the face contains index numbers for position, texture, and normals. I don't know how to order them properly so that my normals would be assigned into correct positions when the engine starts rendering.

  • In ur first suggestion, can I still use that technique if I want to use Element Buffers? since i am duplicating the positions for different normals (this is what i understood) – Ethan Gamat Feb 21 '22 at 16:27
