Model Matrix Transformations: A Change-of-Coordinates Perspective
Model Matrix Transformations
... A Change-of-Coordinates Perspective
My article examines model matrices through the lens of change-of-coordinates transformations.
Rather than treating model matrices as mere transformation tools, viewing them as change-of-coordinates matrices reveals why certain algebraic properties hold. Specifically, I demonstrate the mathematical equivalence between two common rotation approaches:
- Matrix-first: (rotate the model matrix, then transform)
- Transform-first: (transform to world space, then rotate)
