You have an implementation of a geometric algorithm that you would like to contribute? You want us to implement an algorithm that you learned about in the technical paper sessions? You want to know more about the open source and the commercial licensing options for CGAL? You want to present the problem you have to solve, in order to figure out if CGAL might be helpful for you?
Visit the CGAL Project on Booth No. 1118 at the exhibition of SIGGRAPH 2019, Los Angeles USA, 28 July-1 August, 2019!
