CSCI 480/580 Lecture 2 - In-Class Problems

Consider the following 3D surface, which happens to lie in the $z=0$ plane. The front of the surface points towards you as you view of the object (i.e., towards the $+z$ axis).

1. Represent the surface as a set of separate triangles.
2. Represent the surface as an indexed triangle set.
3. Represent the surface as a triangle fan.
4. Write the indices for a triangle strip representing a tetrahedron with vertices a, b, c, d.
