Hi all:
While playing around I came up with a condensation algorithm to reduce (condense) the size of stars. It uses an intensity conserving transfer function weighted by a product of pixel brightness (and kind of looks like the gravitation equation m1*m2/r^2).
I have attached a pixelmath process (NOTE: rename the image to "startest" to use it) which performs the algorithm using an inverse square law and over a 5x5 pixel region. I also have attached a document showing the formula I want to use to generalize this into a script.
Also, can I somehow remove the reference to the specific image, renaming images is a pain...
Let me know what you think or if you think it's useful.
PS: The key usefulness of this algorithm is revealed by multiple applications/iterations.
Cheers
Colin
