No, the 3D calculations were done by the so called "math box". This

Wow...I'd love to get my hands on the design info for that! There
must've been some seriously bright people working on those systems.

I, Robot (1983 - the first 3D/Polygonal game) used a
6809 with
supporting 2901 bit slice cpu's for graphics support. The color
vector Star Wars also used the 6809.
Surely they didn't use the 6809 for the 3D calculations, did they?
I know those games have a lot of optimization (fixed-point, no
hidden-line removal, etc.) but they still seem a bit much for a
6809...
