1.
Identify some physical properties of an object that are not captured by a model containing only a polygonal mesh. (Thus, a polygonal mesh alone does not constitute a complete model of the object.) Explain how one of those properties could be added to the object’s model.
2.
A triangle is displayed with approximate. Suggest a way to improve the accuracy of the shape.
3.
Each collection that follows represents the vertices (using the traditional rectangular
coordinate system) of a patch in a polygonal mesh. Describe the shape of the mesh.
Patch 1: (0, 0, 0) (0, 2, 0)
(2, 2, 0) (2, 0, 0)
Patch 2: (0, 0, 0) (1, 1, 1)
(2, 0, 0)
Patch 3: (2, 0, 0) (1, 1, 1)
(2, 2, 0)
Patch 4: (2, 2, 0) (1, 1, 1)
(0, 2, 0)
Patch 5: (0, 2, 0) (1, 1, 1)
(0, 0, 0)
