Spatial Deformations
Linear transformations
- take any point (x,y,z) to a new point (x’,y’,z’)
- Non-rigid transformations such as shear are “deformations”
-
Linear transformations aren’t the only types!
A transformation is any rule for computing (x’,y’,z’) as a function of (x,y,z).
Nonlinear transformations would enrich our modeling capabilities.
Start with a simple object and deform it into a more complex one.
