If your only source of 3ds files is what you find on the internet, I would highly recommend to not use 3ds. If you work with some artist, see what program he uses and write an exporter for it, that exports all the data you need to a format having all features you need for your program. If you intend to do the graphics work yourself, then learn to use a program and again write an exporter for it. That way you can make your own test files. Having said that, I worked for many years with 3ds files, mainly exported from 3dstudio max, and although furstrating at first, I got the job done with it. Probably I can provide you with some sample 3ds animations from 3dsmax if you want, just contact me privately. I'm no 3dartist though, so don't expect nice things, but I can do enough to help you test features. > What kind of animation can we realise using the > library ? Rigid body animation (includes hierarchical animation too). A 3ds file contains seperate "tracks" of keyframes for position/rotation/scaling, plus you get "linking" information for hierarchical animation (parent/child relations between nodes). It's been a long time since I wrote code that reads animation data from lib3ds and even longer since I wrote code that reads animation data directly from a 3ds file without lib3ds, so I can't give you any more details at this point. -- John Tsiombikas (Nuclear / Mindlapse) [EMAIL PROTECTED] http://nuclear.demoscene.gr/
