Mitsuba Physically Based Render

notareal

Interesting that it works with .XML files. I tried it with the Thea exporter, but got an error. This looks very promising as a free unbiased renderer.

Well... xml is not a universal language. Obviously they use different XML schema Have to say, there is something I like in mitsuba. Worth to keep eye on.

Don't know your system, but if you are using windows, just download the distribution zip-archive, unpack it and run mtsgui.exe. There no installation. Don't forget to load some example scenes they do provide.
I believe this could help http://www.mitsuba-renderer.org/documentation.pdf

It's really what they say, early beta - but interesting concept.

Try to update your display drivers.

thanks for your suggestion notareal, i think it won't work when i do it at office, my VGA is onboard card,
i will try this mitsuba at home.

EDIT: already try at home, but don't know how to open a file or import it (same case like earth mover did), anyway its still pre beta right? this software looks going to be a good one as an open source.

According to the development blog, the Collada importer is ready but only usable via command line (can't figure out how to do this). It seems like the importer will be integrated into the GUI soon, however:

The current version can import Collada files.
To export from SU:

-Make your model a component/group
-Right click > Flip along Component's Blue
-Rotate it +90º on red axis (follow right hand rule)
-When exporting to Collada, make sure "triangulate all faces" is checked and "preserve component hierarchies" is unchecked.

In Mitsuba, just go to File > Import.

That's it. That's all I know for now.
Check the PDF manual. Most of it is technical, but pages 24-25 offer a promising glimpse of Mitsuba's power:

For now, here's a simple SketchUp model rendered with Mitsuba's Path Tracer in 23 seconds on a Core i5:

Thanks, JIm. I had to delete the index.html part to be able to load the site...

The main page shows a lovely image of a "rough dielectric" material (sandblasted glass?).

I remember "mitsu" means "three units" in japanese. So... what does "ba" mean here?

Its a green herb/ vegetable, and the FAQ says that the dev was cooking with it at the time and gives this reference (http://en.wikipedia.org/wiki/Cryptotaenia). It does have a sort of 3 lobed leaf, so maybe thats it?
