Plotting BSDFs

Hey gang,

Besides Andy’s (awesome) BSDFViewer util, does anyone have any other fave ways to plot the distribution of their BSDFs? Anybody have an R or gnuplot script to take a plain old Klems basis BSDF xml file and make a (series of) polar plot(s)?

Hi Rob,

I would be game to try writing something with R. I'm aware of Andy's BSDF
viewer and it is indeed awesome.

Is there a particular project / task driving this interest? Batch
visualizations?

Hey Kyle,

I’m making a bunch of generic BSDFs for window substitution in OpenStudio and thought it would be nice to have a couple of simple data visualizations of each one, for the docs. Kind of a back burner thing, just wondering if this has been done already. What I *don’t* know about R could fill a book, but I do know it’s pretty capable…

OK, we can chat more offline. Certainly good to take a look at what is
available / done already.

Hi Rob,

I used OpenDX to generate nice 3D-solids for selected incident angles from measured BSDF. These could be either exported as vrml or rendered in DX. For the xml-format, you could check bsdf2rad from head, which makes it easy to include a visualization step into scripts.

Cheers, Lars.

Thanks Lars, I forgot all about bsdf2rad!!
