Black hole model does not display properly

[chris]

I'm debugging the problem right now. Are you running with 16-bit color by any chance?

Chris,

Just for your added enlightenment, *I'M* using a 24-bit color scheme.

Take care, Bob

Chris, I can confirm that the new black hole model is still messed up.

Thanks a lot, Frank...

I was starting to think that it was just me again.

Take care, Bob

I just took a look at the new CMOD Black Hole and the black center appears to look okay on my ATI 9700 Pro (32 bit color depth).
However, it seems some other things have been modified ...

* The colored section used to reflect sunlight off the disc material, but no longer does (as reported a ways back in the Bug Tracker).
See old picture below.

* The Ambient Light setting used to affect the model but no longer.

Black Hole - 1.3.1 Final ...

Chris, I'm using 32 bit color on a GeForce 4 TI 4200 with 128 MB video RAM.

I think that I found the problem. Here's a new EXE to try:

http://www.celestiaproject.net/~claurel/celest ... 2-zfix.zip

This sets the default z-buffer depth to 24 instead of 16 bits and the maximum far/near ratio to 2000 instead of 10000. There should be a lot fewer depth buffer problems than with older versions.

Hot Dog! It worked. The black hole and the two spaceship models I reported problems with above are now whole and fully functional. The fix worked on them, so I suspect it will work on the other models I had problems with as well.

Wonderful job, Chris. Thanks for working it through. You are a damned genius!!

P.S. Is there a way to dim down the new Black hole model so that it displays a bit less brightly? The old model used to be dark and required some ambient light increase, while this new model is very bright even with ambient light - none. Something in between would be perfect. Is there something we can do on our end, or would it need a new version to be done to dim it down a bit?

Anyway, thanks again.

Chris,

The Celestia Fix improved my Black Hole model, but it's
still screwed. As you move into the center of the model,
the black hole first disappears, then starts performing all
kinds of neat acrobatics. As long as I stay away from
getting near to the core, it looks fine. It's still messed up
in close though. Just thought I'd let you know about it.

Thanks, Bob
