Planar Interpolation with Extreme Deformation, Topology Change and Dynamics

Summary: We present a mesh-based, interpolatory method for interactively creating artist-directed inbetweens from arbitrary sets of 2D drawing shapes without rigging. To enable artistic freedom of expression we remove prior restrictions on the range of possible changes between shapes; we support interpolation with unlimited deformation and unrestricted topology change.

GPU-Accelerated Locally Injective Shape Deformation

Summary: A highly efficient locally injective shape deformation method with superior performance. We extend the harmonic subspace to support multiply-connected domains, and provide a generalized bounded distortion theorem. We provide a closed-form SPD Hessian modification that leads to efficient Newton iterations. Our algorithm is designed for efficient GPU implementations.

Autocuts: Simultaneous Distortion and Cut Optimization for UV Mapping

Summary: We propose the first UV mapping algorithm that jointly optimizes for cuts and distortion, sidestepping existing heuristics for placing the cuts while minimizing state-of-the-art geometric distortion measures.

Seamless: Seam Erasure and Seam-aware Decoupling of Shape from Mesh Resolution

Summary: We present seam-aware mesh processing techniques that eliminate seam artifacts in textures and decimate a mesh, including its seams, while preserving its parameterization and seam-free appearance. This allows the artifact-free display of surface signals---color, normals, positions, displacements, skin weights---with the standard GPU rendering pipeline.
