This software is truly magnificent for anyone interested in geometry processing. So often, papers are published in respectable venues and no implementation is ever made available. Reproducibility is the heart of science, and it’s such a rare thing (especially in computer graphics). This software provides the source for many interesting and useful recent algorithms in the field of geometry processing, and for anyone doing research in the area (or just anyone who is interested), it’s truly a godsend. I wish that all researchers would make such an effort to provide public implementations of the methods and algorithms they publish.

DescriptionThis images demonstrates some features of Graphite 2.0, an OpenSource experimental 3D modeler. Graphite includes recent research results, from the ALICE INRIA project-team and others. Graphite is available as binaries (for Windows) and source-code (for Windows, Linux 32 bits and Linux 64 bits).

The image shows automatic generation of normal-mapped simplified models. Starting from the Stanford Bunny, a segmentation and U,V parameterization is generated (top left), then the model is simplified (top right), and we generate a normal map (bottom left). Displaying the simplified model with the normal map gives the final result (bottom right). Much less triangles are used by the simplified model, resulting in better performances.

Besides automatic normal map generation, Graphite includes algorithms for U,V unwrapping (LSCM, ABF++, …), segmentation (VSA, MCGIM, …), mesh repairing (hole filling, pliant remeshing, Laplacian smoothing, …) and much more.
