[JAVA3D] Texture Mapping and Loaders

[Alejandro Terrazas]

I sent out a message a little while ago regarding how to apply textures to Shape3D's obtained from a Loader.  So far, I haven't gotten much response although I realize that people were distracted last week.   Here is my basic question:   How can I use texture mapping with Shape3D's imported with a Loader if I don't know what geometry types are used in the objects?   Here is my scenario.  My colleague is giving me dxf files that represent buildings on our campus.  The dxf files are made up of lots of different primitives (as far as I can tell).  Therefore, it is not possible to guess the composition of each Shape3D.  Texture coordinates do not exist on the imported Shape3D and as far as I can tell cannot be added at runtime.  I have a scheme where I can add the coordinates and texture coordinates to a new Shape3D but again I don't know what kind of geometry is used so I can't create a good texture coordinate array to use.   I do remember importing some VRML scenes in the  distant past and getting the  textures but I haven't been able to get them in with any other loaders.  It would be easy to texture map in 3ds and then import the 3ds texture mapped objects but so far I haven't been able to get textures in 3ds to show up in my Java3D scene either.   I suppose I could also extend an existing loader that when it parsed the dxf file also returned the geometry types but that is something I was hoping to avoid.   Thanks in advance for any advice--   Alex
