Hi Phelim, you have to identify the Shape3D node that contains the geometry you want to map the texture to. I don't know about your original file format, but e.g. in VRML you can attach labels to single nodes and reference the equivalent nodes in Java3D. The named objects are collected in a hash

I own a Voodoo3 3000. Java3D will make pretty good use of the card using Direct X. But, in order to get the best performance, you would have to make calls to the 3DFX or Glide GL APIs directly. That would mean using some sort of .dll unfortunately. There some APIs available on the web that do this

Julian, I think you will find that the TextureLoader class does exactly that. Texture images are scaled to be a power of 2. Only if you apply the image directly and don't use the TextureLoader are you responsible for scaling yourself. I think this seems like a sensible compromise. Sincerely, D
