Saturn stripes, Mercury half naked and Cassini's polygons

Hi folks,

Celestia seems to work very smoothly on my machine but there are a few problems:

Only half of the surface of mercury is textured, the other half is perfectly smooth.
Saturn looks great until I look at the North pole: it looks llike the backside of a bumble bee!: there are circular black stripes on the surface.
Some parts of the Cassini spacecraft are intersected with large flashing polygons!

I just bought this computer:

P4 3GHZ
1GB ram
graphic card Asus Ati radeon EAX 300

Can anyone please help me out with these bugs or is my brand new graphic card just not up to the task?
cheers :)

Andy

Do you really want us to dream up craters on Mercury where noone has ever had a chance taking a photo??

You don't really believe that we happened to forget texturing the other half, do you ? ;-)

Do you want us to erase the ring shadows on Saturn's northern hemisphere? Should I show you a Cassini photograph of that "backside of a bumble bee!" ;-) ?

Here is how my Saturn looks like. Can you see the circular stripes in the top Celestia image?

Please, update to the latest Radeon driver!.

My congratulations.

I can't believe I've been so silly as to miss that! :?
I'm so used to computers being the cause of most display problems that I didn't even consider that it's my internal "chip" that screwed up!
Mercury hasn't been photographed completely and those rings on Saturn are actually the shadows of the rings....right.
Thanks for clearing that up for me Fridger.
So the only problem are cassini's polygons. I did update my driver a few weeks ago and nothing changed. I guess I'll try again in case I messed up something there also.
Is there any chance stupid questions get deleted from the system? :wink:

There are no stupid questions.
Other people often make the same mistakes. so it's worth while leaving such threads for others to read.

Speakin of saturn's rings, I too have a slight problem.
When ring shadows are on, I look at Saturn, and it has a lot of black spots all over it, and my computer lags down a lot when viewing it. Is it a problem with my graphics card?

It's most likely a problem with the graphics drivers for your card. You should install the latest drivers, which can be downloaded for free from the Web site of the manufacturer.
