Can glGetError() return the exact problem in OpenGL?

1 point

Yes, it tells me the exact problem in the OpenGL state machine.

Not quite the exact error message--but it can give us something close by returning an enum. Combined with a macro (using the preprocessor), we can even return the line number of the offending opengl command.

Why do you think interpolation is necessary when we specify different vertex colors for each vertex in a triangle?

1 point

This is OpenGL's way to blend colors together. On a per vertex level if each vertex is a different color, then we can get a smoother color shown on our triangles. Visually it often looks better, and it is likely the best 'estimate' of how to fill things in.

OpenGL wants to spend as much time performing additional computations as possible.
