ABSTRACT
Sculpting character deformations that stay on-model for an arbitrary pose is a non-trivial task. Example based methods are desirable, depending on how few sculpted examples they require. After experimenting with various methods, we find the results are lacking from an artistic point of view. The core problem comes down to a matter of Pose-weight Interpolation, for which we present a novel, artist-friendly solution, Constrained Weight Smoothing. CWS computes Pose-weights on an n-dimensional mesh in pose-space such that weights for an arbitrary pose can be evaluated in O(1) time.

Mesh pose-editing using examples
CASA 2007An easy-to-use mesh pose-editing system is presented. We take advantage of both skeleton-based and example-based approaches in order to provide an intuitive way for artists to edit mesh poses. Our system automatically extracts the skeletons of the ...
Pose-space animation and transfer of facial details
SCA '08: Proceedings of the 2008 ACM SIGGRAPH/Eurographics Symposium on Computer AnimationThis paper presents a novel method for real-time animation of highly-detailed facial expressions based on a multi-scale decomposition of facial geometry into large-scale motion and fine-scale details, such as expression wrinkles. Our hybrid animation is ...
Pose space surface manipulation
Example-based mesh deformation techniques produce natural and realistic shapes by learning the space of deformations from examples. However, skeleton-based methods cannot manipulate a global mesh structure naturally, whereas the mesh-based approaches ...
