RST Transforms Pt2
The classnotes include the following sections from Fundamentals of Computer Graphics, 3rd Ed.
Chapter 6
- 6.3: Translation and Affine Transformations
- 6.4: Inverses of Transformation Matrices
- 6.5: Coordinate Transformations
Important concepts:
- Homogeneous vs. Non-homogenous transforms matrices
- Homogeneous vectors for Location vs. Direction.
- Multiplying transform matrices to create more complex transforms
- Rotating/scaling around an arbitary point instead of around origin
- Order matters - the matrix on the right in a multiplication gets applied first
