Milkyway rendering

Post #1by Verz Veraldi » 26.09.2010, 04:13

I was browsing in this forum when i suddenly found this image http://www.quickfixcomm.fr/Celestia/galactic_center.png . anybody know where to get that awesome milkyway rendering? and from the same topic (viewtopic.php?f=10&t=16031&start=15) i've tried PM-ing Chris where to get that star feature but the forum won't let me. if you have it, can you share it?

unfortunately it's not what i was looking for, but it's great anyway. take a look at the image again. the milkyway is made by blobs, not pictures. that's why it's awesome..

Verz,

The blobs shown in the picture that you reference are what Celestia normally uses to draw galaxies, including the Milky Way.

Seeing that image on your screen is a matter of tuning the relative brightness of Stars and Galaxies by typing the parentheses ) and ( and the square brackets ] and [ . Make sure you have galaxy rendering enabled, of course. :)

yea i know that of course.. but no matter how i change the milkyway custom template, the shape of the milkyway still don't look the same.. perhaps it uses a different shaders? the picture is from gaux's post in the thread

Since I coded Celestia's rendering of all 10 000+ galaxies of the famous revised NGC / IC
catalog (in version 1.4.1), I have also prepared a while ago a short tutorial for setting the display of Celestia's galaxies optimally:

viewtopic.php?f=2&t=13348

There are plenty of galaxies for practising the best settings ;-)

PS: As a long-standing design strategy of Celestia we have agreed to model the appearance of the Universe according to its visual appearance (or at best corresponding to the view with a small telescope ) . Hence those colorful vistas of galaxies and nebulae that most add-ons display from long-time photographic exposures are avoided on purpose in the official distribution.

In Celestia.Sci I pursue an extended multi-wavelength approach, as may be seen in some colorful galaxy previews over in our CelestialMatters site.
