2013 - Implicit Skinning: Real-Time Skin Deformation with Contact Modeling
Linear blending has been the primary choice of deformation for many years now. Then comes the Dual Quaternions system, which does preserve volume but deformation often results with bulging and in-appropriate deformation. Check out the Implicit Skinning, which as seen in this demo is a real-time solution to preserve not just volume but also simulate skin contact. Great stuff!
