Efficient and Robust Skin Slide Simulation

How to read this

Category

Method: an efficient skin-slide simulation for characters

Contributions

• Automated simulation of skin sliding tangentially over underlying anatomy from stretching and tissue motion
• An ADMM-based implicit Euler solver with collision handling that exploits local deformation neighborhoods for efficiency and stability
• Integration with linear blend skinning and pose-space deformation for production use

Context

Relates to contact-aware skin deformation in the lineage of Vaillant et al.'s Implicit Skinning, adding the lateral sliding behavior of skin over muscle on top of standard skinning rigs.Builds on: Implicit Skinning: Real-Time Skin Deformation with Contact Modeling

Correctness

Presented as a production-oriented method emphasizing efficiency and robustness; the realism targets the offset sliding behavior rather than full volumetric anatomy, and benefits depend on the local-neighborhood collision approximation, so it complements rather than replaces full physics.

Clarity

Fairly technical and terse; a first pass conveys the goal, a second pass is needed for the ADMM integration and collision scheme.

How to read it

Focus on the ADMM/implicit-Euler formulation and the local-neighborhood collision handling; a second pass pays off if you want to layer skin slide onto an existing LBS plus PSD pipeline.
