Radiance pmap extension on Windows

Hi Valère!

I am using desktop radiance2.0b on windows. As I need to simulate a room
with a deep lightpipe, I would like to use the photon map but I can't find
any version of it I can use on windows.

I think it would be worth to find out the status of the current attempts to update the photon map extension to the Radiance 4.x code base. I am not sure whether Jan or anyone else involved at Fraunhofer ISE is reading, but probably they are the only ones who know about the project.

First, I would immediately stop using Desktop Radiance. We are in 2011 now, and I think the old releases are interesting mostly for historical reasons now.

Second, I do not know how well a patched Radiance 3.7 (the latest official patch of the pmap) compiles on Windows. It used to work find on Mac OS, but Windows is quite different from everything else. You may still consider to use a virtual machine (e.g. Virtualbox, available for free) to get a complete Linux environment on a Windows machine.

Third, as I am doing some experiments on light pipes and the pmap, I would really be curious whether we will have some validation data once a Radiance 4.x pmap is to be released. There used to be caveats which I am still trying to understand.

I imagine that once we have a complete pmap patch for Radiance 4.x, people will get it useable in cygwin & Co., too. Still, probably it would make sense to get your hands on a Linux installation for now. And using a virtual machine is the easiest way to go for people not having access to a native installation.

Cheers, Lars.

Hi all,

the current status of pmap is:

I have a patched version to on of the latest head release (of December
I guess). I've already tested it and made some validations. This looks fine.
I will put it on the server soon (by end of next week or the week after).

For those of you who are using daysim: I've also tested a pmap-version
of daysim! This works in principle (I already used it for a project),
but before releasing some small issues must be fixed first. This will
need maybe another 4 weeks.

BUT: The windows compilation haven't been done or tested....

Best,

Jan
