Indigo 0.6 test 3

[OnoSendai]

Ok, I've uploaded a new version, i fixed halt_time, and perhaps the extreme noise will be gone?

[richie]

hi, thank you nick, i'm gonna test it soon.
a mandriva user on IRC reported that he couldn't launch this version using wine, can someone confirm?

[zuegs]

Some times i have set tonemapping to bright, than i would like to correct exposure for exr, but as it's clamped at <=1.0 i can't but it's ok if it's the desired behaviour.

here a comparision with first uploaded v6t3 (EDIT: after 2mins for each image)


will try new version too

[OnoSendai]

Thanks Zeugs.
is metropolis on?
bidirectional on?

[zuegs]

sorry, nick, for missing infos... yes both bidir and metro was active...

[OnoSendai]

And how many muts/sec were u getting in 0.6 test3?

[zuegs]

Hi Nick,
the noise thing seems have to do with mesh-lights... please have a look at "testscenes\meshlight_test2.xml". This scene is also more noisy on v06t3 than v06t2... hope this helps

EDIT: muts are very good, equal or perhaps even better than v06t2

[OnoSendai]

Hmm.. ok, thanks Zeugs.
I'll have a look at this tomorrow.

[tungee]

nick thank you!
will try out this now.

[richie]

yes,i've got a meshlight scene also very slow.
other than that, it seems faster than test2 , not absolutly sure of that if you take in account that i have increased gamma on postpro to get the same ambiance on test3. both are 12 minutes on my P4 1,6GHz, test3 is on the left:

[Kojack]

First big thanks for Ono master

I make tests too...
Cornell box looks cool and richie have right its faster


Next i dont think soo that meshlight scene are very slow. In my opinion its becouse its burned out.

[zuegs]

Found difference between meshlight and rectanglelight in v0.6t3.
The right image is the original "cornellbox_jetero", the left image is the same scene but with a meshlight instead of the rectanglelight (both with BiDir and Metro ON). This seems to be the reason that some scenes works fine with v0.6t3 and other are noisy. Hope this helps...

regards zuegs

[OnoSendai]

Thanks Zuegs for isolating the problem, solved now

[zuegs]

no problem... any new download yet ?
