Projective Skinning

How to read this

Category

Method: a physics-based real-time character skinning algorithm

Contributions

• A physics-based skinning approach that avoids common geometric-skinning artifacts at real-time rates
• Builds a two-layer model of rigid bones plus an elastic soft-tissue layer directly from a triangle mesh and skeleton
• Requires no skinning weights or volumetric tessellation, and resolves local self-collisions while enabling dynamic effects

Context

Builds on Projective Dynamics, applying its fast constraint-projection solver to the skinning problem as an alternative to linear-blend / geometric skinning.Builds on: Projective Dynamics: Fusing Constraint Projections for Fast Simulation

Correctness

Demonstrated as real-time with dynamic effects and local self-collision resolution; a reader should note 'local' self-collisions and the soft-tissue layer derived from the surface, so global collisions and material realism are not the focus.

Clarity

Accessible idea with a concise model description; a first pass conveys the two-layer concept, a second pass is needed for the projective-dynamics solve.

How to read it

First pass for the no-weights, two-layer (bone + soft tissue) framing and why it beats geometric skinning; do a second pass on the projective-dynamics constraints if you plan to implement it.
