Camera Interpolation: Amy applied Linear matrix interpolation to camera interpolation. This involved re-writing the projection matrix into a more suitable form, looking at three types of interpolation (piece-wise linear, smooth approximating and smooth interpolating) and altering the interpolation when the rotation is too big. Surface parameterization: There are several theoretical papers out there for cutting n-holed tori open along their generator lines (most using a version of minimum spanning tree). Actually implementing these algorithms on real meshes, then using them to create a parameterization of the hyperbolic disk is a challenging problem.
