Spiral staircase (sunlit version + neon/night version)

A little modeling exercise in Blender. This was rendered with 1.0.4. The glare is clearly visible and nice. But I'm in two minds about it. The rendertime hit seems to be pretty heavy. This cooked at 800x600 for over 20h on a P4 and it is still far from clean.

Nice.
Using exit portals?
I plan to mess around with some stuff regarding the glare code.
If it is still too slow, then I'll add the option to compute it in post.

Thanks Ono. I'm only using mesh emitters. I'm not too sure about the slowness. It's more a feeling. I'm rendering a much more complex scene on my quad right now, and I stopped it in 1.0.4 as it had made very little progress overnight (it's a big render, though, at 3200x2400). But then again, 1.0.3 without glare doesn't seem to be very fast either, so it's probably more to do with the scene (lots of geometry, complex multi-layer mats, tons of emitters and glossy surfaces...).
I think either the possibility to do it in post or on the fly would be great for that kind of effect which is difficult to see other than on a pretty clean render. It would make tweaking much easier.

Very cool stuff BbB. I must think of Men in Black.

About the glare stuff... from my experience it is rendered in 2 steps. First you get the normal rendering noise (mostly monochrome, like in analog film) + a bit of glare. Glare gets more and more, but very noisy, the noise is much more like a digital camera, very colourful. And while the glare stuff is still very noisy the rest of the image probably has cleared out very nicely. Doing it in post processing could be pretty nice since the rest of the image doesn't need any more processing power.

Yes I noticed the colour noise. And also (but I could be completely wrong), the fact that it seems slower to clear at the beginning of a render whereas 1.0.3 makes big steps in the first few passes... Dunno, maybe I'm making this up...

very nice! love the design.

One small crit: the concrete seams in your stairwell don't match those on the ceiling

Yep, that's true. My UV-mapping skills are being found wanting

I guess the easy way would be to split the cylinder from the ceiling and just rotate it till it fits...

Actually, it is very unlikely that the seams in the concrete would match in reality - so it's actually more realistic as you have shown it

Nice job!

I guess, architects would look at that and force the seams to match

Very nice, anyway

The PP-glare: will it still use the whole colour-spectrum or will it again be limited to the XYZ-colourspace?
Will it look like real glare or like the one, that's implemented since longer?

ono if your going to mess with glare again why not post that somewhere like in the 1.0.4 section where I talked about some issues
why would we post helpful stuff if you dont talk back

Actually, I feel myself falling in love with glare (under the right circumstances). Here's a sunlit version of the stairway (portal and all), with glare galore. (though the settings are the same - SmartDen Blendigo default)

Wow! I like the new one much better. The glare is much easier to see, more contrast and that little blue tint on the concrete. Neat.

I prefer this one too. I think I'll try to render a bigger version on my bigger machine

The new one is simply awesome!
