Vertex connection and merging added!

[racoonart]

This whole technique stuff is pretty amazing, I didn't understand what bidir really does and why it isn't as fast as pt but solves some problems - (excluding this one here). But I found a page for everyone who's interested to learn the principles:
http://youtu.be/QhJhVkbCgVU hundreds of videos explaining render stuff :)
Now I got it :D

Will Bdir and VCM ever be able to work with HDcache to speed up things ?

no, there is no framework yet to use caching for bidirectional methods

Great find, I will be watching them.

VCM is not unbiased ;-)

VCM is not unbiased ;-)

why do you say that?

anyway, i just want to test it very very very soon, i need it :s

he is right, it is not unbiased, but consistent - it means that when rendering the bias eventually goes to zero with time.

i see , but it's doing a great job here, maybe you should make a 2 hours render of a full test scene with VCM so we can see better.

I see you don't have those funny white splotches, Do you keep "use merging" off ?

[Ondra]

FYI VCM with "use merging" off equal regular bidir

I see, you noticed those splotches I am talking about ?

Also edges get over exposed as soon as I used an environmental light, Coronasky or Hdri

Actually both Bdir and VCM are doing great with direct lights but it gets very noisy and slow if I use environment lightning.

Chakib: Saying that because it is (I am one of the method's authors). But it doesn't really matter, as you want low noise, not some math buzzwords :-)
