Projection matrix! Because why solve a problem with a simple solution when you can use a complicated one! All joking aside, matrix encoding of projective (perspective) transform is widely used so you gotta get familiar with this shit.
Contents
Topics
- Review of perspective projection (divide)

- Homogeneous coordinate normalization
- Derivation of projection matrix
- Backface culling projection adjustment

Bonus Tool
Pindrought (Jpres) from the forum whipped up a visualization tool that helps with projection and various other transforms as a companion to his own 3D series.
