Inputs:
- r4 = p1
- pre-effect rotation matrix
- r5 = p2
- pre-effect translation matrix
- r6 = p3
- post-effect rotation matrix
- r7 = p4
- scalar vector matrix (scales model size)
the preliminary calculation is done as follows:
{Rotation matrix(r4) x Vector matrix(Effect) + Translation matrix(r5)} x {1/4096 * [Rotation matrix(r6) x Vector Matrix(r7)]} x Rotation matrix(camera) + Translation matrix(camera)
{R4 x VE + T5} x {1/4096 * [R6 x V7]} x RC + TC
Produces a table of x y z vectors per model point.
Then assigns an RGB palette to every point and constructs the polygons for the model.
