Assignment 07

Uniform variables are used to communicate with the vertex or fragment shader from "outside". Using a uniform we can access the position of our objects inside the shader from our c++ code. We use this to manipulate the co-ordinates of the object to change the position it is rendered on screen. The uniform functions as a pool of resources that are always available, thus they can be changed after the mesh is built. Rather than changing the vertex data every frame (which is expensive) we can simply add an offset to its position using the uniform and change the place where they are rendered on screen. This is also useful if our mesh is very large. For more vertices, we have a large number of vertex data stored. Iterating through every vertex to modify it every frame is expensive.
