Sure. The "/usr/src/friends/site" directory contains the model and
textures of a new SGI building now under construction. It seems to
load and draw properly.
:I am trying to bring Wavefront objects into Performer.
:The objects load (after I looked at the source code and realized I
:needed to add to the object a "mtllib" line to reference the material
:library), but the texture maps do not. Again, I looked at the source
:code and found that it was looking for an rgb format file, not txc.
It's true. I was never able to find out the file format of those
Wavefront ".txc" files. It is apparently not a public format.
:I fixed this so that all my textures are defined with a ".rgb" file,
:and it loads the object without complaining about not finding texture
:maps, but when it loads the texture map is not present. I've tried smaller
:texture maps, simplifying the material library, etc. Does anyone know how
:to make this work?
If you simply renamed the files, it won't work. You need to get image
files in the SGI imagelib format. If someone can tell me what the
format of the ".txc" files is, I'll modify the loader to be able to
load them directly.
:Also, the documentation in the manuals does not go into any details.
:Are there any pointers to documentation that does?
The Performer Programming Guide, the Reference Pages, and the recent
1994 SIGGRAPH paper constitute the available documentation. This is
the forum for additional questions. What details are you looking for?
:And, while I'm dreaming, does anyone have a loader for a Wavefront
:".pv" file (not ".obj").
We don't, but will happily distribute loaders that people send to us.
:Any help would be appreciated.
