Vesta maps

[Ton Lindemann]

Hello,

I found and prepared some Vesta textures from the HST. Available are:

-vesta-lok
-vesta-lok-mask
-vesta-topo

Here I need some help. As a new user I'm not familair with Celestia. I can't display them with vesta_altmaps.ssc

example;
AltSurface "Topography" "sol/vesta"
{
Texture "vesta-topo.*"
}

Maybe totaly wrong, but can anybody tell me how to set the .ssc file?

I found that my photo-editor isn't able to create .png-files with a transparant layer. Should the lok-mask files with .gif and a transparant layer work too? Gif is 8 kb color dept and .png 24 kb.

I intend to publish the results to the motherlode.

Thanks for help,

Ton Lindemann

Your ssc file looks OK, although you should get into the habit of always using the correct capitalization: "sol/vesta" should be "Sol/Vesta". The correct capitalization is especially important for image file names. Linux systems require that the filename be exactly the same in a Catalog or 3D model as it is on disk.

Check to make sure your texture images are the correct size. They must be a power of two on a side: e.g. 1024x512.

Type a "~" (tilde) to turn on Celestia's console log. It may have some useful error messages. (You may need to type a space after the tilde.)

Sorry, no, GIF is not supported.

I use NetPBM and ImageMagick to combine pictures to create image files that contain Alpha channels. Both packages are freeware and available for all platforms: Windows, Mac and Unix/Linux. See http://netpbm.sourceforge.net/ and http://www.imagemagick.org/.

I intend to publish the results to the motherlode.

Great!

Selden,

Thanks, I installed image magick and need to study the commandline options first.

Cheers,
