+![](https://github.com/BrunoLevy/geogram/wiki/geogram_banner.gif)
+
+Geogram is a programming library with geometric algorithms.
+It contains the main results in Geometry Processing from the former
+ALICE Inria project, that is, more than 30 research articles published
+in ACM SIGGRAPH, ACM Transactions on Graphics, Symposium on Geometry 
+Processing and Eurographics. It was supported by two grants from the
+European Research Council (ERC): GOODSHAPE and VORPALINE.
