Shouldn't Duke be a duck? It just makes sense.

Alright heres my problem, i just downloaded JOGL and was using one of the demo's on NeHe to test it out. When i started it up all the colors and textures were not shown, instead where all the colors and textures were suppose to be was colored red.

My comp is pretty old, Pentium 233 or something. But my apps for Java3D(OpenGl version) works fine. In fact the reason i use the OpenGL version of Java3D because the textures and colors didn't show in the DirectX one!

???Any tips/suggestions/solutions to my problem?

:PAnd no, I won't just get a new comp and try it on that one.

What graphics card  do you have?
Do you have the latest drivers for it?

I have an S3 Inc. Virge MX 4MB?. Its using the latest driver, since the company doesn't make drivers for that card anymore.

DirectX gets this little error that might explain the problem.

Hardware accelerated Direct3D 8+ is not available because the display driver does not support it.  You may be able to get a newer driver from the hardware manufacturer.

But then again, the Java3D OpenGL version allows me to see textures and colors.

Oh, and this is on a laptop, so changing video cards is not a solution.

So any insight to what might be causing this?

Are you sure Java3D doesn't fallback in a software emulated drawing or something like this?(I confess that it may be hard to find it though.)

Java3D *will* use software rendering if necessary.

My app used to run (very very slowly!) on a P133 laptop in this mode.

EDIT:  I believe that this was just the OpenGL sofware renderer though, not anything specific to Java3D

The Java3D only switches to software rendering when i view an app at full screen, other then that i think its running on hardware rendering.

Does anyone know if you can switch manually between software and hardware rendering in JOGL? That might solve my problem.
