• [X] Ryan - examples showing use of test support methods and classes (add to Twiki ShapeTools FAQ).
• [x] Ryan - read more more warp related papers.
• [ ] Ryan (with Craig) - preliminary project definition.

New Business

• Discussed considerations about Jeff rejoining the ShapeTools group.

Discussed

• methods to determine whether an angle of a polygon is convex or concave (
• how to tell if a point in 3-space, yet not in a (triangulated) face of a mesh, is 'in' the mesh shape. No conclusion reached, but a usable substitute would be to project the mesh points onto a plane fit throught the points of the mesh.
• types of (2d) warp solutions.
  • complexity: thin plate splines < elastic warp < fluid warp

Decisions

• Fly project will need elastic or fluid warp
• thin plate spline warp would be useful in it's own right.
