reminds me of stuff i based in basic when i was a kid made me laugh to see "no raytracing", then immediate use of the perspective projection which is intersect

  Deriving the perspective projection equations involves intersecting a ray and the projection plane, but this doesn't magically turn a rasterizer into a raytracer.
