DIFFEOMORPHISM SPLINE

Diffeomorphism Spline

Conventional splines offer powerful means for modeling surfaces and volumes in three-dimensional Euclidean space.A one-dimensional quaternion spline has been applied for animation purpose, where the splines are defined to model a one-dimensional submanifold in the three-dimensional Lie group.Given two surfaces, all of the diffeomorphisms between th
