PTGPU vs BidirMLT

... but why do they look so much different??? Should end up looking (quite) the same

Hi Zom-b,
there's an outstanding bug with bidir that gives dark edges on some glass. I'll have a crack at it when pixie sends me the scene.

I see your edumaction finally paid off eh?

Indeed, there was a page in the book on fixing bidir bugs!

Hey Ono, I know about this bug and I live with it since along time

But this here looks different! The edge darkening due to BiDir appears on edges, here they are the same for both renderings.
Its more about some missing reflections, just check the bowl to the right, no reflection of the lightplane for BiDir!

I really hope you can finally squeeze this glass-edge-darkening Bug, but this here seems to be another building site!

I've done another test and let both run for the same time parallel, and then did the difference between both.

Bidir: 4860 spp

PT: 17550 spp

Difference

Ouch, that would mean that one of the methods is slighlty biased with these materials? Using Indigo to render glass materials at work, I'll have to pay more attention on this. How does this compare to MLT?

This looks like non-reciprocal BRDF issues, no?

The cube experiment

Epic cube but not as much as companion cube

Companion cube is so sweet, and such a good friend!

It looks brilliant, but I would prefer a darker, more saturated wood texture and there are some smoothing issues on the edges of the chair.

Smoothing issues are a bug with GPU acceleration which I believe lycium said the team was working to fix.

Tea's served!

Very nice! A GPU powered tea pot

Very nice! A GPU powered tea pot

Finally, I can have infuse millions of tea leaves per second! I will rule the tea making market

Very nice! A GPU powered tea pot

with bits of anti-grav tech, as i can see))

my contribution
the overall idea of the composition isn't entirely mine,but i really liked playing with light and fog (that's not a dirty lens, that's fog!=)
