I'm trying to model fixed slats at arbitrary angles that have been covered up by diffusing roller shades. Is there a workflow of radiance routines (e.g. genblinds, xform, etc.) that can make this a simple procedure?
I was working on this question here, but that thread is now focussed on work-arounds in WINDOW.
Yeah you just sorta listed the workflow of Radiance routines in your question. =)
genblinds is a nice way to generate venetian blind slat type thingys, and it's pretty configurable (e.g. slat dimensions, spacing, and angle are all arguments to it). And then yes xform can easily transform the resultant geometry to a specific location of the model, and you can "instance" the genblind-created geometry all over the place, with minimal memory impact.
So a single scene (.rad) file with both the blind matl, genblinds command into xform and the diffusing shade matl and geometry? (consider me a nube)
You could do that, yeah. I usually have the materials in a separate file (or files) and just make sure I call those first when I make the octree, so they are defined before oconv reads in the geometry files that reference them. But yeah you could have a single file that defines the blinds and shades, and then reference that file (again via xform) throughout your model with a series of other xform calls that array the things around the place. Make sense?
