I installed official Celestia 1.4.1 on Linux-KDE without addons. When I use DOT3 ARBVP, the Moon and Mars surfaces have a great 3D-look but they show black stripes parallel to their equators, no matter if I use the lower or higher resolution textures. There are 1-4 strips, that vanish in the dark night areas of the surface and disappear when I zoom out enough. Sometimes, toggling "Show orbits" makes the position of some strips to change.
Running from command line:
Code: Select all
Loading required GL library /usr/X11R6/lib/libGL.so.1.2
Initializing ARB vertex programs . . .
(...)
All ARB vertex programs loaded successfully.
render path: 3
The graphics card is a nVidia 7600GT with the latest (1.0-8762) driver, though the stripes were also present with a nVidia 6600, using the same driver and Celestia version.
Basic and Multitexture modes work as expected, but I liked a lot the DOT3 ARBVP effects. Can anybody give a hint to investigate?
