Work 06: If your shapes don't look solid, TRI a different ANGLE

Due: Monday 4/8 10:00am

For testing & submission purposes, please use the shape testing script from the previous assignment.

The Drawing:

• Create new functions to add a polygon to a matrix, and go through the matrix 3 points at a time to draw triangles.
• You should have a new triangle matrix that exists alongside the edge matrix. The edge matrix should be used for the shapes that are exclusively 2d (lines, circles, splines), and the triangle matrix for our 3d shapes.
• Anything aside from shape drawing that modifies/uses the edge matrix (apply, clear, display, save) should now modify/use the triangle matrix as well.
• Modify add_box, add_sphere and add_torus to add triangles to the new triangle matrix instead of points.
• Make sure the parser calls the draw_polygons functions when needed.
