A simple GUI testbed for 3D processing and visualization. Cross-platform (Windows, OSX, Linux). Source code is written in C++. Required library for [3D viewer] (http://www.libqglviewer.com/).

Implemented algorithms:

• Mesh simplification using quadric error
• Sampling (regular recursive, Monte Carlo, sphere packing, voxels)
• Skeleton extraction
• Smoothing (Laplacian, scale-dependent, mean curvature flow)
• Space partitioning (octree, kdtree)
• Mesh voxelization*
• Subdivision (loop, modified butterfly, longest edge)
• Minimum oriented bounding box (OBB)
• Coordinates (mean value coordinates, Green coordinates)
• Curvature* (polynomial fitting, two other implementations)
• Deformation (As-rigid-as-possible (ARAP), Linear Rotation-Invariant Coordinates, FFD, voxel deformation)
• Skinning with dual quaternions
• Colormap
• *Mesh Browser display 3D thumbnails of all meshes in a folder
• re-meshing

(Note that there are no GUI tools ready for you to use these. You have to write your own as in the rotation example provided.)
