Agenda
Lecture 8 Assignment
Due at the start of class, Wednesday, September 30.
Please submit answers to these questions
either as a hard copy (typeset or handwritten are OK) or by email to
terescoj AT strose.edu by the start of class. Please use a clear subject line
when submitting by email (e.g., CSC 112 Lecture
8 Assignment , Joe Student). We will discuss these
questions at the start of class, so no late submissions are
accepted.
- For a bit more practice with constructive solid geometry, create a
three-dimensional Pac Man object, with his mouth open.
You need not run this in
Python/Ambrosia or generate an image, but you may do so if you
wish. (6 points):
- Write (or type) out an Ambrosia definition for a tetrahedron constructed as
a Mesh object. You need not run this in
Python/Ambrosia or generate an image, but you may do so if you
wish. Recall that a tetrahedron is a
polyhedron (like the cube and pyramid we saw in class) except that it
has just four faces and are all triangles. Your tetrahedron should be
centered at the origin and have one of its points facing up and
aligned on the y-axis, but you need not worry about keeping all of the
faces the same size.
Note: ensuring a regular tetrahedron - where all four faces are
equilateral triangles - would require some careful calculations using
trigonometric relations. We will construct a regular tetrahedron in
class, but you need not do so in your submission. (8 points)
