Recursive Subdivision
•General
method for building approximations
•Research
topic: construct a good mesh
–Low
curvature, fewer mesh points
–High
curvature, more mesh points
–Stop
subdivision based on resolution
–Some
advanced data structures for animation
–Interaction
with textures
•Here:
simplest case
•Approximate
sphere by subdividing icosahedron
