Re: NVidia and texture maps

Hi Don,

I ran into the same problem with a GeForce card. It's come to be known here as the "black bug". We gave up on the GeForce cards and went with the older TNT2s. However, I recently ran my stuff on a Linux box that I was told had a GeForce card (maybe a 4) with the latest Sun JDK and Blackdown Java3D with no problems. So there is hope.

Hi Jim-

Thanks for the feedback.

Have you tried the 1.3.1beta to see if that helps?

Hello Don,

my Linux box runs XFree86 4.2.0-8 with an NVidia
GeForce 2, and experiences problems when using
Blackdown's Java 3D 1.3.

Things such as filled land-masses [ie. Gridded2DSets
passed to DelaunayCustom.fill()] are not displayed,
and flash briefly onto the screen as the display is
zoomed.

Blackdown's Java 3D 1.2.1 works fine, except for
offscreen rendering, which almost causes the machine
to lock-up.

Hope this helps,
Jim.

Hi-

A couple of us have run into a problem using Java 3D 1.3
from Blackdown on Linux with an NVidia GeForce 4 card.  The problem
manifests itself when a display with a texture map is shown.
Any other lines (like the VisAD box) turn black.  An example of
this is Test16 in visad/examples.

Has anyone else experienced this and have a work around?
One workaround we have is to use Java 3D 1.2.1, but I would
rather have a solution that takes care of the problem using
Java 3D 1.3.

Thanks for any help.

Don
