In the lecture slides, we saw the following code to draw a buffer in modern OpenGL:glDrawElements(PrimType[object], NumElems[object], GL_UNSIGNED_BYTE, BUFFER_OFFSET(0)) ;The third argument to glDrawElements denotes the type of the vertex indices.Given our code as is, how many unique vertices can be referenced by each face?______
Why must we explicitly write code to compile the shader at run-time?.
A. GLSL is an interpreted language.
B. No real reason; we could compile it along with our CPU program.
Convenience for the application programmer, to more quickly modify shader programs.
D. The shader code is compiled to run on a GPU, which may not necessarily have the same instruction set architecture as our host machine.

D. Window operations (resize, close).
