Eclipse shadow bug at major planets! Need Advice

[Buschmann]

I have an Elsa Victory II with Voodoo Banshee Graphics Chip. Works fine with simulation unless a GeForce would be better. But I encountered a problem a showed in this picture below! It doesn't appear at eclipse simulation on Earth and Moon, only on Jupiter, Neptun and so on...

What the hell is that? I've got the latest drivers for that chip, got the latest drivers from http://www.glsetup.com

Who could help?

The Voodoo3 doesn't support setting a maximum mipmap level, so you get 'leaks' at the edges of the shadow texture. I'll have a patch for the Voodoo3 and other non-OpenGL 1.2. compliant cards very soon (possibly even later today).

Would be cool!!! Thanks

Ok . . . give this a try:

http://www.celestiaproject.net/celestia/files/ ... -patch.zip

It's a 370K zip of celestia.exe . . . copy it over your existing celestia.exe (which is probably in c:\program files\celestia) and let me know if it fixes that crosshair effect with eclipses.

Works fine! Thank you! Good work!
Best simulation ever! Thank you!

Now the eclipses look fine, but if I want to go to Mars or Pluto, I get an error message:

Sorry that is german, but means Celestia caused a ("splitting error"?) in module.


Only if I want to zoom to Mars or Pluto, until I find more destinations!

[chris]

I'm having trouble reproducing the problem . . . Does the crash occur when you zoom to Earth or Mercury?

No, I selected Mars, pressed G to go there, I approached the planet and some km's before came that error message and the programm crashed. Happened only with Mars and Pluto til now.

[Buschmann]

This error occured when I was trying to go to Phobos moon:

???????

[Laahel]

hellow again

chris, just tried your patch, no more "axes", but there is alwas the "twin" shadow problem that appears on the other side of the planed, showed in my previous shots...

same problem with the program crashing by going to mars :/

Hey Laahel

thats pretty scary, that you face the same problem. And that twin shadow problem occours on my system too.

Greets

[Laahel]

yeah

in fact, the crashing problem seems to be a voodoo problem since there is no crash with the Matrox G450 ...

the twin shadows appear with both voodoo3 and g450 so, maybe a celestia bug ???

had anyone else experienced the problem ??? ( put ambiant light to see the dark side of jupiter for exemple, and see an eclipse shadow at the exact oposite of a normal eclipse shadow on jupiter )

I do also see these "twin shadows" but that doesn't bother me so much the way the crashes do!
I think Chris makes a good job and it was extremely helpful that he programmed this patch for celestia after I posted my problems.

This is software development at its best and he will do his best to solve that "crashing" problem, I think.

[Laahel]

yeap, wonderfull program, and i know chris, will make it the bugless possible....
that's why we post here ;p

bye

[ron]

i am only using the plain vanilla graphics card that came with my PC but all the rendering in celestia works fine except for the eclipse. I too get the crosshair effect with and without the patch file. that aside ... great program

[chris]

I'm still working on this problem . . . it's difficult, since I can't reproduce the crash on my system. Thank you to everyone here for all the testing of the patch . . .

The patch does a test to see if the maximum mip map level feature is supported by OpenGL. Apparently, this test doesn't work on everyone's system, so I'll have to come up with something else.

The twin shadows problem happens when the ambient light level is set to something other than 'none' . . . I think I can produce a fix for this, but it may not work with older graphics cards.

Anyhow, keep watching this thread for updates on the eclipse shadow problems . . .

--Chris

[chris]

Here's a possible fix for the problem . . .

Try putting this Mars texture:

http://www.celestiaproject.net/celestia/files/mars.jpg

into Celestia's textures/medres directory. Then visit Mars and see if you can look at it without crashing. If it works, I'll post a fixed Pluto texture as well.

There's some code in Celestia that doesn't properly deal with non-power of two textures. This code needs to eventually be fixed to report an error instead of crashing, and the few non-power of two textures in Celestia have to be resized.

--Chris

[Buschmann]

Hey Chris

seems to work with that new texture, I can even go to Phobos and Deimos!!!

Would be cool if you make a new texture for Pluto

Greets

[chris]

Very glad to hear that this worked . . . here's the fixed Pluto texture:

http://www.celestiaproject.net/celestia/files/pluto.jpg

Let me know if there are other textures that give you problems.

--Chris

[Buschmann]

Yeepeeh!!! It works!!! Pluto looks great!

Thanks to the best software developer ever!!!
