Forward projection
Representing 2D point as a fictitious 3D point (x', y', z') [for matrix calculations]
Convention: Given (x', y', z'), we can recover the 2D point (x, y) as
World to camera trafo
- Translation of -C as seen in W-CS
- Apply rotation Rcw to get P in camera coordinates pc = Rcw (pw - cw)
