Our upcoming SIGGRAPH 2015 paper “Linear Subspace Design for Real-Time Shape Deformation” is online now. This is joint work with Yu Wang, jernej Barbič and Ladislav Kavan. One way to interpret our contribution is a method for computing shape-aware (rather than cage-aware) generalized barycentric coordinates without a cage. Another way to interpret it is as a generalization of linear blend skinning to incorporate transformations of region regions/bones and translations at point handles. The distinguishing characteristic of our weight computation is its speed. The choice of handles (the choice of linear subspace) is now interactive and becomes part of the design process. It absorbs user-creativity just as manipulating the handles does.
