quadric intersection curve calculation
I was searching for a methode to compute the intersection of two (or more) quadric surfaces. During my research I found this website:
It shows exactly the solution of my problem. After searching in the Git repository, I am still not sure which function(s) I have to use to get this result. I want to include the computation into a Java/C++ project. I would be greatful if you could give me some advice which function(s) I have to use to get the cut curve of general intersections of quadrics and also the drawing function.
I would be also very happy if you give me the source of the implemenation for example a paper or book reference.
