>>technical term is for rendering an object with it's EDGES disturbed by the bumpmap<< displacement mapping. There is also something called hypertextures that I believe adjusts the geometry also but I don't know much about these. >>And …. er …. Is it possible/hard etc to write an IPAS that would do this or would that be something which would have to be implimented in the code of the 3DS.exe<< Hmmm, I don't know what info is available to an IPAS but it might be possible. Very impracticle though, it would be much more efficient built into the renderer. I don't know if any PC programs have displacement mapping. To do it, it actually modifies your geometry and will make it really complex by having it model all the bumps of the map. When I had the opportunity to work on Alias I was told about this kind of mapping, but the person showing me about it said that it takes a lot longer to do then simple bump mapping; and this is on a silicon graphics machine! It would be nice too have this but as far as I know it is too much for a PC. Maybe some IPAS writer is working on this, I would hate to see how complex objects got though. Maybe if it only modified the edges and where objects intersect you could get the effect and save alot of geometry. I dabble in 3D crap and have an idea how to produce displacement mapping without modifying geometry but it's all theoretical. Hopefully Yost Group will find a way to implement this, I think they easily could. ———–Will
