The document discusses different types of surfaces that can be represented with polygonal meshes, including: 1) Discretely swept surfaces of revolution which are created by rotating a base polygon or profile around an axis. 2) Implicit and parametric representations of surfaces using functions of x, y, and z coordinates. 3) Ruled surfaces where every point lies on a straight line on the surface, such as cones, cylinders, and surfaces swept by a moving line. 4) Quadric surfaces which are 3D analogs of conic sections and have traces that are conic sections when cut by a plane.
