Indigo 0.6 test 1

@mzungu

Hmm, ... this is odd, I did a rendering with .EXR and some lights
and just the bidirectional MLT seems to be broken. If I render
with bidir enabled then it turns black after some minutes. Without
bidir everything seems to work fine.

Can you post the scene that is giving you trouble? ;o)

edit: btw. ... does Indigo work at all for you, with sky+sun
or just the skydome?

take care

psor, yes I had bidir on. I'll try it this morning with it turned off to see what I get. Thanks!

(Yes, this latest test build has worked great other than when I tried an env map. Love the multithreading!)

EDIT: tried it just now with bidir set to false and it still faulted. It does give a different message when trying to combine spherical with .exr files:

Code: Select all

ImageExcep: Error encountered while reading RAW image.
Fatal Error: ImageExcep: Error encountered while reading RAW image.

But I get the other message on .float or .raw images within the spherical tags and when using either within the latlong tags.

I'll try using the regular 0.5 release in a bit to see if its just my system or not...

Can you post the env_map bit of the scene xml mzungu?

Sure thing! It's here:

Code: Select all

	<env_map>
		<spherical>
			<path>kitchen_probe.float</path>
			<gain>1.000</gain>
			<width>640</width>
		</spherical>
		<!-- <latlong>
			<path>uffizi_cross.exr</path>
			<gain>1.000</gain>
		</latlong>  -->
	</env_map>

Nik, also note that I just now tried it in 05-test7 and its rendering as we speak. Its still early, but it appears to be utilizing the above .float file properly. I'm confuzzled.

hmm.. so it's broken in 0.6 test1.
Ok I'll have a look at it

Its just odd that it seems to be working for others (like psor.)

Yepp, ... it's odd, ... my env settings look like this:

Code: Select all

<env_map>
	<latlong>
		<path>HDR/photostudio.exr</path>
		<gain>0.005</gain>
	</latlong>
</env_map>

System Specs: AMD64 3000 @ 2,3Ghz , 2GB Ram ...
Indigo Release: v.06 Test1

I rendered with HDRI and four area lights for 14h ... without a problem,
but bidir ... anyway bidir was not yet fixed and looks like a hard nut. ;o)

But honestly, ... I use .EXR only for HDR lighting in Indigo, so I don't
have a clue if it is a format thingy. ?(

take care

What software or source do you use to get your EXRs? I've used the little hdr2exr util linked elsewhere in this forum, but that may be the prob. Then for the RAW format, I've used HDRShop to convert HDRs. These worked in 0.5, but I'll have to try it with an EXR & latlong.

BTW, what does the gain setting do?

EDIT: Yep, tested latlong EXR on the same scene in 0.5 and it renders.

@mzungu

I'm using the same lil' tool to convert my .HDR to .EXR ... ?(

*Gain setting

As far as I know it controls the 'power' of the HDRI map, but it's hard
to notice because of the whitebalance that is doing the trick ... I'm
totaly guessing here ... *LOL*

Nick, one other tidbit that may be helpful, after noticing psor's system specs: I've got a dual-proc system (running WIn 2k) that I'm testing with. I've been running indigo "single threaded" (with no -t option) on these env_map tests, but I recall that somewhere you mentioned that indigo spawns two threads anyway, even without turning on two "render" threads. This may have an influence on things with my dual setup.

I did run 2 threads on previous non-env_map renders of this same scene and it had no probs (and was very fast!

) so maybe this part of the code is the cause?

YES!!!! Indigo works great on my intel iMac dual 2.0 Ghz. I'm getting 146000 mutations with the dispersion_test file.!! This is awesome. Thanks for this great program NIck!!

Regards,

Peter

146000 mutations per sec

Ono: Here's a screengrab from the dispersion_test on my Intel iMac.
It's really fast I think.

Peter

ps. I don't have a 3d program on my computer, so I can't test bigger scenes. Is there a test scene I could download? Thanks!

lol.... Mac + Intel...
two compannies I realy don't like

So just to keep the Rock rollin' here the same Scene with my AMD X2 3.800+
with 2 2GHz Cores (so its the same Clockspeed like your peer!)

But to be realistic, the Core2 CPUs by Intel will rock the Party much more...

P.S.
Try to raise the thread Number to 3... I get about 5% more speed by this!!!
