EXERCISES FOR WEEK 8
|
| week8-1 |
Without writing a program (just use calculator), using Newell's Algorithm, calculate "face normals" for each face of
the barn as defined in class. |
| week8-2 | 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. |
| week8-3 | 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? |
