Dr. Schrempp,

I found the following under the Mars section of my solarsys.ssc file...

Mie 0.0024
MieAsymmetry -0.15
Rayleigh [ 0.0010 0.0006 0.0003 ]
Absorption [ 0 0 0 ]
MieScaleHeight 20

Is this simply something you left over in 1.5 Pre3? Or, should this be left
alone so that us poor English-speaking Bozos can wonder what's going on
here?

Thanks a lot, Bob

Bob, I suppose that's a question for Shatters, and ok, I'm not Fridger but I can tell you those settings are already used by 1.5pre3 under the OpenGL 2 path rendering. You will find similar settings for Earth and Titan...
They are used to describe some more realistic atmospheric effetcs...

Bob,

this one and only time I disagree with Christophe ;-)

Why should this be a question for shatters.net?

I dare to pretend that I understand these Mie theory parameters better than anyone (including Chris L.) . In my "youth" I even published scientific papers on Mie theory...

Soon or later I will present a tutorial about the precise meaning and tunings of the Mie & Rayleigh parameters.

What's up here is of course a much improved description of the scattering of light on the small droplets of planetary atmospheres. This is one of the significant improvements of Celestia 1.5.0 over 1.4.1.

Cheers,
Fridger

Appreciate the explanation good doctor... I didn't even KNOW about Mie
theory. I thought that you had perhaps left some German words in the
Pre3 version by mistake. Give me time please... I'm still getting back
up to speed on Celestia.

Many thanks, Bob

By the way, I asked this question on the other forum too, but is anyone
else able to press the ENTER key while in Celestia to go to asteroids?

For some reason, I CAN go to Borrelly and Halley - the comets - and I can
also go to SOME asteroids. However, if I try to type in 'Geographos' or
'Kleopatra' the associated asteroids cannot be found. Is there some other
issue I'm missing here?

Both of the offending asteroids are defined in the Celestia data folder in
'asteroids.ssc.'

Many Thanks, Brain-Dead Bob

Bob, Bob, Bob... I recall you that this is not a Celestia hot-line!
Let us keep if possible these questions about Celestia for the Shatters forum...

Oops...

Sorry Miss Lisa... Honestly, did NOT know this rule. Please feel free to
DELETE this thread if you like.

Thanks, Brain-Dead Bob
