Grant Hutchison has provided an update to his [url=newtextures.zip]http://www.lns.cornell.edu/~seb/celestia/hutchison/newtextures.zip[/url] which includes separate surface and cloud texture maps for Venus. See http://www.lns.cornell.edu/~seb/celestia/hutchison/index.htmlfor details.

you might like this 1024 x 512 Deimos texture to go with your 1024 x 512 Phobos

That's nice. :D
It does need to be mirrored north-south to work correctly with the deimos.3ds mesh object, though.
I actually smuggled a 1k Deimos from the USGS into my newtextures.zip file, derived from the same data as you've used, but it looks like you've sharpened the contrast and brought out a lot of the small craters.

Are you using a flipped Phobos map, too? The effect is less obvious, but it does look better (and is correct!) if it's mirrored north-for-south.

Yes, I did thank you
I flipped Phobos, and all the others that was in the update zip, on Seldons site

Thanks again 8)

Hi grant,

this deimos-texture from Darkmiss works correct. I compared it with this Viking Orbiter images.

It seems that deimos-textureres shipped with celestia 1.24 and 1.25p7 are incorrect (must be mirrored).

The Deimos map with Celestia is conventionally orientated - it's what you'll find in the books, with north at the top and west to the left. The trouble is that when it is pasted on to the 3DS mesh object for Deimos in Celestia, the map gets turned inside-out! So to make the final image of Deimos appear correct, you have to pre-treat the map - mirroring it north for south does the trick, and the final object then appears correctly orientated. That's what I've done with my replacement texture map, and what I was suggesting Darkmiss do with his.
