(Information Science Master) Lecture on Computer Graphics by Professor Kenji Igarashi.
- Definition: Shape processing in the field of computer graphics (shape representation, shape generation, shape deformation, etc.).
- Shape Representation
- Parametric Surface
- Subdivision Surface: Ensures continuity at the seams (smooth?) (by the president of Pixar).
- Recursively subdivides to achieve smoothness.
- Weighted Subdivision Surface
- Allows setting sharpness weights for each edge.
- Can handle cases where only one edge of an object needs to be sharpened.
- Also a patent by Pixar.
- How to perform deformation
- Free Form Deformation
- Distorts space by manipulating control points (like a cage surrounding the object).
- As-rigid-as Possible Deformation
- Grabs and moves points within the object.
- Free Form Deformation
