Smooth Contact-Aware Facial Blendshapes Transfer

How to read this

Category

Method: contact-aware facial blendshape transfer

Contributions

• Improved blendshape synthesis via deformation transfer that addresses penetrations and surface crumpling
• Virtual triangles to preserve spatial relationships between separate face parts
• Laplacian smoothness constraints, with reported use in film production to reduce facial rigging labor

Context

Extends Sumner and Popovic's Deformation Transfer for Triangle Meshes by adding contact and smoothness handling specific to faces.Builds on: Deformation Transfer for Triangle Meshes

Correctness

Targets a known failure mode (interpenetration and crumpling) of plain deformation transfer; validated through reported film-production use rather than a formal benchmark, so the evidence is qualitative and practitioner-oriented.

Clarity

Concise and applied (DigiPro venue); a first pass conveys the fix, a second pass clarifies the virtual-triangle construction.

How to read it

Focus on how virtual triangles and Laplacian constraints are added on top of deformation transfer; a single careful pass suffices for most readers, a second pass only if implementing.
