[Radiance-general] rpict command for photon mapping

[Katsuya Obara]

Hi Greg,

I even don't get "0% done".
Followings are the result when I tested your suggestion.
1.What happens when you run the same command without the photon maps?
I tried rpict -t 60 -ab 1 -vf view.vf model.oct >test.result. Even in this case, I couldn't get "0% done".
2. What happens when you run with the photon maps and -ab -1?
I tried rpict -t 60 -ap global.pmap 50 -ab -1 -vf view.vf model.oct >test.result. Also in this case, I couldn't get "0% done".

Does this mean that I have problem in rpict command not in photon maps?

Thank you for your help.
Regards,
Katsuya

Hi Katsuya,

With the -t 60 option, you should at least get a "0% done" message after initialization.  Is that message even showing up?  You might not see reports every 60 seconds if the scanline writes take longer than that, but you should at least get the initialization output.  If you are not seeing that, then something else must be wrong with your command, or the photon map(s) are not loading correctly.  I don't know how to verify this, other than regenerating the maps and trying again.

What happens when you run the same command without the photon maps?  What happens when you run with the photon maps and -ab -1?

Does anyone else have experience/suggestions to offer?

Cheers,
-Greg

Hi Greg,

Thank you for your reply.
Below is the command I tried to run for rpict.
rpict -t 60 -ap global.pmap 50 -ap caustic 200 -ab 1 -vf view.vf model.oct

Following your advice, I changed the command to add output redirection as below.
rpict -t 60 -ap global.pmap 50 -ap caustic 200 -ab 1 -vf view.vf model.oct >test.result

It seems that I could run command but it does not report any progress. Are there any specific format I should specify for output file?

Thank you!
Regards,
Katsuya

Can you offer any details about what process is starting all the (unsuccessful?) rpict commands?  It seems that there is no output redirection, so this is not even a command you would normally run.  What is running it for you?

Best,
-Greg

Hi all,

I am trying to create rendering image using photon map.
Following the photon map extension user manual, I could run mkpmap command.
But when I try to run rpict command, it seems that they keep trying to run the command and failing as following image.
Can anyone advise me what is causing this problem and how to solve it.
Thank you very much for your help!
