Coloured Planets

Post #1by Bluespace » 10.10.2005, 06:48

I don't have the lavishness of graphics cards, but untill yesterday Celestia worked perfectly on my system, which is a p4 2.0, 256 mb ram and Intel845G onboard graphics with 64MB

yesterday i updated the driver for graphics, then suddenly, my earth began looking damn good, and at the same time the MOON is showing so many colours in it, blue, pink etc, also the mercury, mars, etc is showing fuzzy colours, also i at the poles of MOON i can see clearly the a point with so many colors flowing from it

what could be the problem i installed 1.3.2 and 1.4.6pre both are giving the same problem,

Unfortunately, up through v1.4.0pre6, Celestia uses some OpenGL functions not supported by Intel's graphics library. That is fixed in the current code, which has other problems, though.

You might try
http://www.celestiaproject.net/~claurel/celest ... 2-conf.exe
(which is a full Celestia distribution)
and perhaps augment it with
http://www.celestiaproject.net/~t00fri/celesti ... re-FT1.zip
(which adds some new code for rendering galaxies).

Be sure to read the thread
New Celestia-1.4.0pre-FT1 (galaxies) for Testing

It's long, but discusses some of the problems.

Intel graphic chip lies when reporting its capabilities.
To get rid of the psychedelic colours, try commenting out all bumpmap references in your *.ssc files
It is not a perfect solution, but at least, it is a workaroud :(
I have the same problem with my Dell610 laptop at the workplace.
For a further and better workaround, replace all your surface textures with shaded versions. It looks almost as good as with bumpmap textures.

OK, it is working now with version 1.4.0pre-FT1 on Intel graphic chip :D
Just add the /ell_galaxy_arb.vp/ shader in the /shaders/ directory to get access to the /OpenGL vertex program/ path (ctrl-v keyboard command).
The shader is to be downloaded from CVS.
See this here (thanks t00fri): http://www.shatters.net/forum/viewtopic.php?t=8105
