   drawing bones
  Is there a way to draw the bones of a skinned mesh in wireframe mode?How can I go about doing this? 
  ''Bones'' in d3d are not really something you can visualize straight away.They just represent weighted transform matrices, and as such, they can affect, for example, every vertex of the model with some weight. It would be very difficult to calculate a physical ''bone'' geometry.You could calculate a given bone influence''s bounding box and draw it.Or, better way of visualizing bones is to draw the geometry vertices with a color indicating how much a given bone affects the mesh. ;  The bone influence bounding box would work.  Is there anything in DirectX that calculates the bones bounding box like D3DXComputeBoundingBox or maybe I can use that for each bone? ;  No, there's not a DX function for automatically calc bbox of bone influence.Calculate the bounding box of all the vertices that the bone affects at all (or to some treshold, if it suits you). DX does have a function called GetBoneInfluence (or something like that) to help determine the said vertices.   [edited by - Nik02 on August 4, 2003 5:09:40 PM];  Thanks for the idea. I will work on it.
