Nebulae in Progress

StevieJ got me started on this. We'll see where it goes.

First attempt:



I'll do some more tomorrow.

Ok wait, that's a real pic, right 3D? It looks pretty real. Steve here made it sound like someone was rendering Nebulae!

Damn, this is HARD! AHH. Here's a pic of the stars so far though...



The big ones need more work... they use [[[[2]]]] motion blurs. I can't believe I'm doing this. Surprisingly it renders in 1.69 seconds with 9x AA.

I'll also be adding in colors to the stars, but that's a toughy, anyone got suggestions?

and here's the diamond shaped one. i would have submitted this long ago had i just been able to get the larger stars right.

cool. thanks, steve

i'd still like to see how 3D is doing his

trust me, he made it. you can tell if you look at it closely.

O for crissakes!

I was happy with the stars (although they could have a softer glow) but the nebula that is supposed to be the main thing here is not all that exciting. Besides, you can only do one type of nebula with the filter at the moment.

The stars are done in three "layers" at three different sizes and the beams are motion blurs.

The nebula is the real issue here. It's got no depth and detail. And should be lit by starlight from surrounding stars to be more realistic. The real question is how much variation (with somewhat realistic results) could be achieved? There is plenty of variation between different nebulae like in the samples StevieJ posted. (Galaxies are their own thing, so I'm not going to try and do them here.)

I've got some other things to do for a while, so you have plenty of time to get there first...

3D, could you post your filter? I just want to see the guts.

You cab even look at them with Google Earth.....

I've always liked the perspective of this one.....

Preview from above filter

Nice direction, Sphynx!!!

Hey steve, how about the next time you post nebulae, you put in one post

there was a show on PBS about how they photograph and then render those images, steve. what you see in the images is not what the camera saw. they are essentially photoshopped a bit. actually, they have their own software for this, not photoshop and the colors correspond to different gases. they have their own RGB set where oxygen is blue, hydrogen is red (i think), and green is something else. i forget the complete method, but basically, what you are seeing is not what the camera saw, not exactly. still, it's freaking cool as hell and i always like perusing the NASA site. i even watch the NASA channel on satellite at times.

also, thanks, sphinx for the filter! i'll most likely take a look at it.

Something like that shouldn't be too hard to create in FF, but it will be rather slow. There are several planet/moon filters in the lib, and if you dig up that normal map thing, you can actually shade the planets from the nebula light..

LMAO.....

Look forward to seeing what you come up with.....especially if it's realistic!!!

Here's that original attempt.



Hubble.ffxml

Here's some info on how they color the images:

an early attempt at a new procedure.

Meh, I think I might keep trying... That custom space anomalies idea I like though.

I got some SL work to do too though... Anyway...

That Rotated Sphere snippet looks great

I'm also doing some Terragen 2 Stuff, Sometimes I try to get inspir-- OMG I gotta go make a filter

thanks, steve. long ways to go, though.
