EXERCISES FOR WEEK 3
|
| week3-1 |
Without writing a program (just use calculator), using Newell's Algorithm, calculate "face normals" for each face of the barn on page 290 of the text. Check you answers with those given on page 291.
|
| week3-2 | For each vertex of both roof sections of the
barn, calculate the normal vector for that vertex, using the fact that vertex normal = sum of face normals sharing that vertex. Normalize these 6 vertex normals. |
| week3-3 | Use Newell's method to find the normal vector for the polygon having vertices (1,1,2), (2,0,5), (5,1,4), and (6,0,7). Is the polygon planar? |
| week3-4 | Do problem 6.2.2 on page 293 of the text. |
| week3-5 | Do problem 6.2.3 on page 293 of the text. |
