Different rendering
Well, i have this problem: i made an application that display hte solar system where for the for planets's appearance i used textures. The question is: if i run it at school works fine, at home planets are whithout textures and i miss a piece of the application tha display a single planet. Why?
The same JDK,
same java3d version
same s.o. (win2000)
Different Video adapter: at school a poor s3, at home a Voodoo3 3000.
Perhaps there is something about the drivers?
Thanks

Thanks, i will try.
But, another thing, i have another thread called undesired holes, i have an update: i tried my program on another pc, with another video adapter (matrox g400), i got another problem, only fews triangles are displayed and in stranges colours. What means? Great incompatibilities of Java3D and all display adapter 's driver or only problem with colour table of that one?
DirectX and OpenGL, which Java3D uses, are designed to work with any graphics card, unless it is too old.
First make sure both have a supported OpenGL or DirectX version. Also, since Java can use only the desktop colors, you should set these (under Control Panel | Display in Windows) to 16-bit or 32-bit color (with a few million possible colors) instead of 4-bit or 8-bit (with only 16 or 256 total colors). For the hole problem, make sure to set CULL_NONE because Java3D decides whether a face faces forward or backward by the order of vertices specified (clockwise or counterclockwise) and if culling is set then some faces may get culled because they are defined the wrong way. Also, for quads make sure you give vertices in the order they are on the border of the quad (top-left, top-right, bottom-right, bottom-left for example), or you may get holes.
