Alternate Textures and Atmosphere

Post #1by rbarbera » 02.10.2003, 11:24

I'm a beguiner user of Celestia. Until now, I have seen the jpgs on some users page, but my graphics card can't support Celestia in a usefull way. Now, I have a new computer with a GeForce 4 (64Mb), so I'm exploring Celestia and I'm very pleased with what I see!.

Yesterday, I have downloaded the 90Mb of the 32K Earth VT. Wow!, I have spend almost a complete orbit of the ISS in realtime, looking the Earth below!

Looking at the ssc files, I have seen that this texture is implemented as Alternate Surface (AltSurface) and reading the documentation for this extension I have mised the ability to define a higer resolution CloudMap. On the current version (1.3.1pre11), the CloudMap is defined inside the Atmosfere {} wich belong to the main object. But I think, that for a efective use of multiple resolutions this will be better located inside the AltTexture. For bodies with atmosphere a better surface (more resolution), usualy requieres a better cloud cover to obtain a full experience.

Any way: what a wonderfull program!.

As far as i know you can define a cloudmap in the altsurface. and if you look at its name, Alt-Surface, you can olny modify the planet's surface, and the atmosphere(and clouds) is not a part of the surface of a planet.

I have tried to define a "denser" cloudmap in an AltSurface and didn't works.

Yes, I know that. But if you don't want to add an AltAtmosphere, the simpler way is to extend the concept of AltSurface for "AltEnvelope" and use it for define both the surface (colourmap, specmap and bumpmap) and the atmosphere.

De Espa?a, en concreto de Valencia

there is no such thing as "AltAtmosphere"...

Yes, and this is the reason I say that Celestia will be able to give us the freedom to change the CloudCover inside an AltSurface.

Bueno, hay varias pistas: por ejemplo, el giro "sos" es muy argentino, al menos latinoamericano. Aqu? en Espa?a decimos "eres". Por otro lado, el dominio de tu cuenta de correo (.ar) tambien da pistas :wink:

And the remark "Born in Argentina" ... (this could be recently added, I must admit it).
The Marado planet is also very helpful... :wink:

The "Born in Argentina" was added long time ago, but i just forgot that it was there.
And about the planet, have you downloaded it?

There's currently no support in Celestia for alternate cloud layers, either via AltSurfaces (where CloudMap does nothing) or AltAtmosphere (which doesn't exist.) Perhaps in the future . . .
