   Joints, bones, and animation?
  Well sorry for being so vague, but basically I wrote an exporter for 3dsmax.  This exporter only takes the actual structure(mesh) of the object.  I am not exporting any of the animations.  So basically my question is, where can I find information on animations and bone structure/joint stuff?  I have my own model format as it is right now, but I would like to get info on how to incorporate animations with joints.Any info will be helpfull, thanks guys.Also, it shouldnt matter but I am working with DirectX9 and C++.--Brad   
  The object that you're animating with bones has a modifier(ClassID SKIN_CLASSID) that gives you an interface called ISkin. That interface gives access to the bones. See the sdk docs for details, also the ascii exporter example is useful.Btw don't try to interpolate the bones yourself with the parameters. Instead, sample the bone matrices with GetNodeTM and save those.   ;Quote:Original post by antistarThe object that you're animating with bones has a modifier(ClassID SKIN_CLASSID) that gives you an interface called ISkin.

Like a doc, tutorial, or book?Thanks much!
