In this video I will show you how to use Vertex Array Objects (VAO) in OpenGL in order to make it simpler to switch between groups of vertices that are characterized by different source buffers and different vertex layouts. I will also describe the compatibility and core profiles, show how to enable the core profile using FreeGLUT and describe how they affect the VAO. Finally, I'll review some changes that I've made in order to move most of the application code into a class.
