I was looking for a tutorial on 3D systems for vertex collisions (using C # and XNA , since I have readily available), but they only managed to collect the pieces. At the moment I have a pretty good understanding, but in my understanding there is one pretty big, clear hole.
Basically, my problem boils down to: how do I get policies and their information?
Does anyone have any good links?
Note: while I use XNA, and I am most interested in this system, it is rather self-education, and I am interested in how to do it on other systems if it is done differently (for example, OpenGL, etc ..)
Explanation: What I mean by “how to get policies” is if I have a 3D object and maybe even an animation applied to this object, is there a system for extracting information (positions, etc.) testing policies? The most logical task would be to get poly information after rendering it, but it also sounds extremely expensive, and I'm not sure how to do it anyway. I was not sure if there was a better way, or if getting the displayed information at this level was even possible.
