Re: NVidia and texture maps


I'm running RedHat8 with a Nvidia Quadro4 900XGL.  I just installed
SDK 1.4.2_01 with Blackdown's Java3D 1.3.1 beta and the "black bug"
seems to have gone away.  I have Nvidia's most recent drivers installed.

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

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

Hope this helps,

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.
