Lecture 4: Transforms (23)
bufudash

What is the point of homogenous coordinates? Since we can do this transformation in 2D, and homogenous coordinates just uses 3D. Does this just simply for the purpose of making higher dimension transformation simpler?

I think the general idea is to use homogenous coordinates to more easily represent transformations through matrices and simplify the math formulas through the w-coordinate.
