Missing lok masks

Post #1by praesepe » 19.06.2003, 14:56

Hi,

When testing the new Celestia 1.3.1 pre4 i've noticed that some bodies have a lok AltSurface defined but the lok textures are included on the base package. These are the cases of Mimas and Triton. The default textues that come with Celestia have cloned areas, especially in the case of Triton, so I decided to produce them on my own:

This the one for Mimas:

For Triton I've also noticed that the base texture has seriously cloned areas that fake parts that we already have in the 75% coverage texture of Voyager 2. For my personal installation I use the cloned texture for "normal" texture and the Voyager 2 with lok mask on the "limit of knowledge surface, take a look:

Not cloned

I can make this textures available if any one is interested :)

P.D. I've also noticed that the AltSurface definition for Mimas doesn't include the Colour and Blendtexture parameters as the "normal" has, so when you change to lok textures also the colour changes.

Code: Select all

AltSurface "limit of knowledge" "Sol/Saturn/Mimas"
{
   Texture "mimas.jpg"
   --> Color [ 0.75 0.63 0.58 ] <--
   --> BlendTexture true <--
   OverlayTexture "mimas-lok-mask.png"
}


I'm guessing if it's not a bug :?
Greets :P

Praesepe:
Masks for Triton and Mimas were included in the CVS tree, but I guess they didn't make it into this release.
Thanks for pointing out the omission in the AltSurface for Mimas - I've corrected this in solarsys.ssc so that it should be in the next release.

Some of saturn's other moons (Rhea, Dione, Tethys, Enceladus) have grey or white areas , where the voyagers didn't photograph. Since we now have LOK masks, shouldn't we also have imaginary textures for the unknown places on those moons?

Since it's been done for many other moons, why not these ones?!
