HI I''m only just starting to build 3d engines, I''m interrested in building a first person shooter (isn''t everybody?). Anyway, I''m not sure how to do about it, I''ve done some research into BSP trees etc but I don''t really understand. I need some help in building a basic 3d rendering engine with collision detection. I don''t care about all the fancy lighting, shadows, texture effect etc etc. I just want to get a basic engine up and running and hopefully learn something. Thanks in advance Craig Wanstall Manager Silent World Studios

Here''s what a simple 3d world is composed of: You have the "world", or whole map, whatever you want to call it, which is made up of sectors, rooms, or areas, which are made up of many polygons, which are made up of vectors, which are made up of points. Keep that hierarchy in mind when designing your engine. If I were you, I''d create a real simple world, where you have a camera that just moves around a small sector, to get the idea of how it''s done. Then I''d create one using BSP trees. It may take a while to get your BSP engine done, but once you do, it makes everything else (collision detection, etc.) sooo much easier. Plus it''s fast.
