Distant Galaxies

[WAS]

Kinda just a test to see what I can do with TG.

Procedural stars (of course) and now procedural distant galaxies/clusters

These are scaled down from 6k due to JPEG compression issues and filesize (6k were turning out 4mb-5mb with bad compression).

Like! Look like the  - how did they call the Hubble photo? Deep field?

[archonforest]

Nice!

[Stormlord]

Very good idea and it looks realistic in combination with the starfield.
A Jordan Deep Field as I would say...

Here is the starfield background, and distant galaxies merged into one function, and rendered with TG filters instead of photoshop.

[Jo Kariboo]

Indeed, it is quite close to Hubble photo!

The composite renders go much faster then merging together. Oh well. Can still easily, and probably better, to render out a HDRI for anything animated.

PS Here is a simple idea for how the function works, though what I have now uses a PF for bands instead of a built in perlin. But i think the build in perlin looks better just not as customizable.

This is really close to what you can find on the astronomy websites from true life telescopes ! Amazing realism !
