Hello,

I've released a new version of Luminous Bloom today, a utility for 
casting glare from the bright regions in your images. You get get it here:
http://news.povray.org/povray.binaries.scene-files/thread/%3C4c0ebe6b%40news.povray.org%3E/

New in this version:

  * completely rewritten core routines
  * different effects via point sets
  * can handle up to 65536 points
  * a file for writing your own custom point sets is included
  * a scene for viewing different point sets is also included
  * it's roughly 50% faster

I changed the whole thing to work based on the principle presented by 
Tek in his thread "Lens flare in scene."* It was optimized by using a 
suggestion made by Alain in the same thread.

The attached image shows the star burst effect in action. The seven 
effects included in the zip file are shown at the bottom. The banding in 
violet sky is a jpeg artifact, it wasn't my fault ;)

Happy ray tracing!

Sam
