Alternately, if the textures were applied with a 4 point warping on polygons
with more than 3 vertices, The Reality Engine hardware will handle this
correctly but the lower end graphics will make it look like faceted
triangles. In this case the modeler was possibly trying to remove some
perspective from the image using the mapping. This will work on higher end
graphics but not on others. You may have to unwarp the image using image
processing tools and reapply the texture.

Subject: [Info-MultiGen] : Misapplied textures
Hi All,
In my lab we use Viewpoint Datalab's realtime library of OpenFlight
models. All the models look great on our Onyx and Onyx2. However,
on our Octanes and O2s the textures of certain models (f-15s,
eurofighters...) seem to be misapplied. It looks as if the texture
coordinates are screwed up. I've reported this problem to SGI and they
have been able to reproduce it, but haven't been able to give me a cause
or a solution. If anybody has seen this problem and/or can offer a
possible solution, it would be greatly appreciated.
Thank you much,
Bryan Walsh
