Lab 7: 3D Hierarchical Modeling

Alex Benn and Andrew Frampton

Quick Summary

In this part, the hierarchical modeling system was modified to work with the challenges posed by three-dimensional coordinates. This included expansion of the Module functions to include the recently-developed 3D Matrix functions. Also, the Module_draw function was modified to work with the 3D perspective projection.

Questions

1. We implemented Module_shearZ(), which applies a shear in the z-coordinate.
