How to create a dust ring

Post #1by thefallenghost » 17.05.2009, 18:55

Hello,
How can I create a dust ring (or any type of ring) around a certain star?
Thanks.

There is a topic about this subject here;
viewtopic.php?f=7&t=13209&p=110267&hilit=fomalhaut#p110267

I must admit that the image I created in that thread was mostly acheived using post-processing with Gimp; but I did manage to make a relatively acceptable dust ring for Fomalhaut. I used a large billboard centred on the star, duplicated to appear above and below the ecliptic (otherise it disappears when you are inside it).

Then how do Saturn's rings work?

Saturn's rings are defined in the .ssc file for Saturn.

I've put rings around stars in the same method, (placing an ssc ojbect inside a star) but it always looked weird. The ring was not illuminated the same from all directions, and other glitches made things look worse.

I have placed a dust ring around Fomalhaut using a dsc object, with a custom template image thing. It looks fairly acceptable.

You might also wish to examine some of Bertrand's add-ons on the Motherlode.
Just have a look at some of the ring systems he has created for the Star Trek
category. His user-id is bdfd.

Some really different, and interesting large ring systems for asteroids.
Just a thought. :wink:
