Sadly, it looks to me like bugs in the S3 graphics drivers.
The drivers claim to support OpenGL v1.4
This is indicated by the line
Version: 1.4 15.13.15.05

OpenGL v1.4 vertex shaders are used by Celestia to draw highlights on the Earth's oceans (specular reflections) and to draw shadows on the sides of mountains and craters on the Moon and on Mars.

Please type a ctrl-V several times, so that Celestia selects Basic (which uses OpenGL v1.1) and then Multitexture (which uses OpenGL v1.2) render paths. Does the Earth look OK in those two modes? (I suspect it will; it won't show highlights on the oceans, though.)

If so, then it is a problem in the OpenGL v1.4 vertex shader program code of the OpenGL drivers for the graphics hardware. You should try to report the problem to S3 . If they don't know there's a problem, they can't fix it. They may require you to report the problem by way of the company that made your computer, though. That'll make getting a fix take longer

[Desperate]

Thanks Sheldon.
Typing ctrl-v don??t help.
I will try to report to S3.
This new laptopp is the first one of mines, witch is angry to the good Celestia.

Still Desperate

[Desperate]

So i mean.

Thanks SELDEN , perdone.

Desperate.

Desperate,

I'm sorry it doesn't work for you.

You can use Celestia with Microsoft's software OpenGL drivers by turning off 3D hardware acceleration.

Instructions:

Open the "Start / Control Panel / Display Properties" menu. Select the "Settings / Advanced / Troubleshoot" tab (not the "Troubleshoot..." button). Move the "Hardware acceleration" slider all the way to the left. Click on the "OK" buttons to change the settings in use. This will cause Windows to use Microsoft's Generic OpenGL v1.1 library, which is limited and can't show all of Celestia's eye candy, but seems to have relatively few bugs. It even works on 2D displays, but it draws everything using software and so is quite slow.

Thank you Selden again.
Celestia is working.


Less desperate now.

I have a suggestion for celestia developers. I have via chrome9 graphics adapter. It is a laptop with no option for upgrading so I have to do with what I've got. Now I love celestia and my request is I think simple enough. I have tried various ways to overcome this issue and I have found one that is promising. I just tried it for Earth and it worked well. I just substituted makesphere function with a model of a ball. So it would be very nice if you could make a fix or something that would change every makesphere function with a real 3d model of a ball?

I don't understand... What exactly did you do to make this work? Did you edit solarsys.ssc and set the mesh for Earth to be a 3ds model of a ball?

--Chris

[abrasax]

yes

[abrasax]

So is it possible or not? Celestia is the best presentation software that I ever used. I would much like to use it on my laptop, but if it's not possible the least you could do is tell us.

[selden]

abrasax,

Unfortunately, Chris Laurel is the only person who would be able to fix the problem, and he's busy finalizing the v1.6 release of Celestia. I suspect that changes to "makesphere" would require substantial work and would postpone the next release for a long time. Simply using meshes breaks Oblateness, VirtualTextures, specularity and other visual displays related to Celestia's representation of planetary surfaces. There are quite a few features which depend on the current representation of planetary bodies and which do not work on fixed sized meshes.

However, have you tried the workaround of disabling or reducing hardware graphics acceleration? Did it work? How much of a performance penalty did it cause? i.e. what's the difference in Celestia's fps (frames per second) ? Type a ` (back-slanted apostrophe; it's usually on the same key with ~ tilde) to see the fps value in the lower left corner of Celestia's window.

[abramson]

I have a VIA Unichrome in my laptop (crappy graphics) and Celestia rendering is better when Antialiasing is *dissabled* in Celestia (Ctrl-X, or Menu Render > Antialiasing). With Antialiasing ON, I have a multitude of thin squares instead of the blobs that paint the galaxies, which I recover with Antialiasing OFF. Try what happens in your system dissabling antialiasing...

[abrasax]

With hardware acceleretaion turned off fps is around 2-3 which is unusable. I realise that a patch would be hard to make and that there is only a few of us having such problems. Anyway thanks for your help. Maybe in near future via will have mercy on us and decide to fix the drivers

[selden]

Unfortunately, the developers of Celestia can do nothing about the drivers.
You need to contact the manufacturer of your graphics chipset and report the problem.
If nobody tells them that something is wrong, they'll never fix it.

[abrasax]

Just to let everyone know, windows 7 automatically installs wddm drivers which WORK with celestia. Drivers are for vista but work nonetheless. So we poor chrome9 users can finally enjoy the full beauty of celestia.
