The George W. Woodruff School of Mechanical Engineering Georgia Institute of Technology Homework #4 Parametric Surface Modeling Due: March 1, 2007 ME 6104 Fundamentals of Computer-Aided Design Spring 2007 LEARNING OBJECTIVES FOR PARAMETRIC SURFACE MODELING: Learn parametric surfaces: Hermite, Bezier surface patches Learn composite surfaces and continuity Understand the applications of parametric surfaces in geometric modeling In this assignment, we will study the application of parametric surfaces in the context of tire model from Homework 3. Consider the tire model displayed here. Two bicubic Bezier surface patches are used to model the section. The section should span 45 degrees, so 8 sections are needed to go around the entire tire. To complete the tire model, each section needs to be mirrored about the Y-Z plane, just like you did in HW3. The surface patches must all have G 1 continuity. Use the same cubic tire profile Bezier curves from HW3 to
