Accelerated Quadratic Proxy for Geometric Optimization

A Matlab implementation of the paper "Accelerated Quadratic Proxy for Geometric Optimization".

---

The class OptimSolverAcclQuadProx.m implements the accelerated quadratic proxy optimization algorithm described in the paper for the minimization of geometric energies.

This package includes a few examples:

• example_deformation_2d_gecko_IsoDist.m demonstrates the minimization of the Isometric Distortion energy for shape deformation (Figure 1 in the paper).
• example_parameterization_cow_IsoDist.m demonstrates the minimization of the Isometric Distortion energy for parameterization (the cow of Figure 12 in the paper).
• example_deformation_2d_bar_ARAP.m and example_deformation_3d_boy_ARAP.m demonstrate the minimization of the As-Rigid-As-Possible energy for shape deformation (see https://goo.gl/skatVH and https://goo.gl/iYXJaP for video clips).

Compatibility and dependencies: The code was tested with Matlab (2015a). The code depends on a few MEX functions. Windows (x64) binaries are included; they are compiled with Intel C++ Composer XE 2016 with Microsoft Visual Studio 2013; compilation requires Eigen; fast implementation of As-Rigid-As-Possible also relies on libigl. The source code is provided under the mex/ folder; run compileAllMex.m to compile all mex files (only tested under windows).
