First let's think about how to rotate some really simple points such as (0,0) and (1,0)
First we'll use the slope intercept form of a line to define each frame along a straight line.
First we need to make sure we understand exactly what happens in the split & average steps.
First we'll review weighted averages of two points and extend the idea to three points. Practice weighted averages of two points in Environment Modeling if you haven't seen it before.
How can we calculate a weighted average between two points? (pssst. This video is super important).
Next lets build a diagram that break rotation into smaller parts. The next exercise will give us a chance to build our understanding of this diagram.
Let's look more closely at how light behaves when it strikes an object. We'll cover diffuse and specular surface responses.
