GEORGIA INSTITUTE OF TECHNOLOGY School of Aerospace Engineering AE 4375-6380 MIDTERM EXAM Craig Open Textbook Only – 45 minutes Duration F99 1. Comparing Volume and Solid models from your projects: (a) Why are solids easier to work with? (b) When are Volumes a better representation? (c) Why can’t you create a topologically incorrect CSG solid? 2. Consider a 2D problem with two points, A and B, as shown below. Assume that it is necessary to stretch the distance apart so that B moves 20% away from A along the direction AB to a new location, B* (with A remainig fixed). Develop the necessary transformation to accomplish this. 3. We showed that a straight line with uniform parameterization between points p 0 and p 1 can be constructed from a Hermitian curve by specifying B =[ p 0 p 1 p 0 p 1 ’} T where p 0 ’= p 1 ’= p 1 - p 0 . a. For a cubic Bezier curve, determine the location of points, p 1 and p 2 to create a straight line with uniform parameterization between p 0 and p 3 (first and last points).
