Two-Layer Sparse Compression of Dense-Weight Blend Skinning

An efficient two-layer sparse-compression technique that substantially reduces the computational cost of a dense-weight skinning model, with insignificant loss of its visual quality. The technique can work directly on dense skinning weights or use example-based skinning decomposition to further improve its accuracy.

Implicit Skinning: Real-Time Skin Deformation With Contact Modeling

A geometric skinning method handling elbow collapse and skin contact effects in real time. Starting from a geometric skinning, the method exploits the advanced composition ability of volumic representations to adjust and control the skin deformation at bone joints while naturally handling contact and preventing any loss of detail.

*Cages: A Multi‐Level, Multi‐Cage Based System for Mesh Deformation

*Cages smoothly deform a mesh by using multiple cages with different coordinate types at different levels, increasing control over the deformation and allowing fast evaluations and low memory footprint.

Cubic Mean Value Coordinates

This method for interpolating both boundary values and gradients over a 2D polygon builds on an existing transfinite interpolant over a continuous domain, which in turn extends the mean value interpolant. The method gives a closed-form formula for boundary constraints represented as polynomials up to degree 3.
