Day 7

2
Looking more at the Garland/Heckbert
implementation

• To start discussion of texture space vs. object
  space areas
• Discussion of subset placement versus optimal
  placement
• Discussion of the mesh manipulations I perform to
  compute the answer

3
Weighting texture spacecoordinates

• A mesh can be covered by many materials
• Those materials may be mapped at different scales
  (example head vs body)
• So we need to scale texture coordinates somehow
  so that they make sense relative to object
  coordinates
• Different scaling coefficients per material

4
Optimal Placement

• As opposed to subset placement
• Solving a minimization problem on the matrix
  expression vTQv
