Hello, i want to speed up my program a little bit. At first, i tell you what i exactly do. I compute intersectionpoints of 500 planes with a Cube. These are view port aligned planes. So the problem is that i compute the intersection of a plane that has at least 3 intersection and a maximum of 6 intersections. With the intersections i form a valid polygon and render it with glBegin(GL_POLYGON) .. glEnd(); Then compute next box-plane intersection. How to speed it up ? I cant use displaylists because the intersectionpoints will change frequently. greetings, xiaowei
