For single-directional path tracing the OpenCL renderer has a lot of nice advantages, and is probably what we'd recommend even on CPU (AMD have a pretty good CPU OpenCL implementation).

I am just a too big of a fan of BiDirMTL. Any suggestions on that, or insights for the future?

With recent changes we could support MLT, at some extra memory cost, however in the Bidir + MLT combo I'd say it's mostly bidir bringing the party... so before we do MLT we should do bidir :)

Bidir on GPU is pretty damn difficult, but one way or another we should be able to manage it, in time... definitely not for the 4.0 release though!

Thesquirrel: Obviously they are not taking away the other rendering methods just because of the new GPU rendering. BiDir and MLT are staying AFAIK (and don't forget the exciting new photon mapping for CPU rendering!) .

Oscaj J understands my troubles. :D
I am glad that you guys are developing and thinking ahead, just don't forget the good old CPU! But, as Oscaj J reminded me, new photon mapping seems promising. Btw, isn't photon mapping something like cheating in unbiased rendering, don't know much, just asking... :)

Photon mapping does introduce a small amount of bias. But if that's what it takes to render caustics in a pool in 15 minutes instead of 15 hours, I'm all for it.

I see, and understand perfectly! Knowing what Indigo is capable of, that photon mapping is going to look awesome, no matter the biasing! :D

Normally, I would be ashamed of that. But, in this case, I am not! :D
Hey guys, I was just thinking something, since you are planning to implement GUI for tabulated spectra, will this also apply, for example, to the diffuse channel as well? When the chat was still working, someone wrote that GUI will be added to every channel that can be wavelength depended, sooo...that would actually be amazing. Truly amazing.

P.S
What happened to the chat window?

Any chance a material preview made it into the 4.0 release? :)

Hi

If possible caustics could be added in post-production with Photoshop.

Why not render any "real "caustics dude?

Your water needs some waves (bump or even better displacement!)
Then your sun needs to hit the water to cause caustics!

Yup, skip the caustics for evening scenes like that, and put a few IES spots in the pool instead.

Beautiful shot by the way! Love that really red light and the way it's spreading between the houses.

Hi Contegufo, nice to meet you; I'm italian too :)

...to tell the truth, the aim of your post is obscure to me, at the moment.. :lol:
