Patate is a header only C++/CUDA library for graphics applications released under the MPL license.
It provides a collection of Computer Graphics techniques that incorporate the latest innovations from INRIA research teams working in the field. It strives for efficiency and ease-of-use by focusing on low-level core operators and key algorithms, organised in modules that each tackle a specific set of issues. The central goal of the library is to drastically reduce the time and efforts required to turn a research paper into a ready-to-use solution, for both commercial and academic purposes.
The library is still in its infancy and we’re actively working on it to bring you the latest of our published research techniques. Modules will be dealing with graphics domains as varied as multi-scale analysis, material appearance, vector graphics, expressive rendering and 2D animation. Okay, right now only multi-scale analysis and vector graphics modules are available, but if everything goes as planned, this sentence should be properly deleted in the upcoming months!
Patate Library is an open-source software developed by Inria
A subdivision surface character (3D model courtesy of Peter Eriksson) is animated and rendered using Modo ray-tracing engine. Three poses are shown in the middle: our screen-space mean curvature (depicted on the top with concave regions in red, convex regions in blue) is used to modulate a basic shading (bottom-left) yielding an exaggerated appearance (bottom-right). The image on the right illustrates another shading modulation based on our offset measurement τ .
