Blend Skinning
Blend skinning is a technique used to deform 3D models, particularly articulated ones like humans or animals, by blending the transformations of underlying bones or joints. Current research focuses on improving blend skinning's accuracy and efficiency within various 3D representation frameworks, including neural radiance fields and point clouds, often employing neural networks to learn optimal skinning weights or using alternative deformation models like dual quaternion blend skinning to mitigate artifacts. These advancements are driving progress in creating realistic and animatable 3D avatars from various data sources (e.g., images, videos), with applications in virtual reality, animation, and computer graphics. The resulting improvements in realism and computational efficiency are significant for numerous fields.
