[Radiance-general] Radiance Utility to Identify Geometry Identifier Name

Wed May 27 11:57:50 PDT 2015

Hello Rob & Thomas,

Thank you for the input, I wasn't aware rvu had the 'trace' functionality. I just used it to render an image and successfully identified my polygon of interest. This was sufficient for my purposes. I appreciate the help.

Kind Regards,
Andrei Kolomenski

You could just use the "trace" command in rvu too; it will return the coordinates of the surface, and then the modifier. But I think Andrei wants specifically to query the output HDR, not the octree. (?)

Greg has developed just such a tool. rvu has a command line option that allows you to query the surface under the cursor. I don't have a Radiance installation around but you should find it in the man page.

It was either that or a cunning pipe between the output of rvu (view direction) and rtrace to report the modifier.

Hello Dear Radiance Community,

I'm curious if it is possible to identify a specific geometry primitive identifier name in a .rad file given an .hdr image of the octree that uses this geometry .rad file? I have a .rad geometry file that contains numerous polygons and it would be helpful to be able to identify a specific polygon identifier name by simply clicking on its surface within an .hdr image. This is useful for debugging purposes, where the geometry consists of a large number of geometry primitives.

If anybody has developed a Radiance utility that performs this task, I would greatly appreciate it you could share it or give some insight into the procedure.

Best Regards,
Andrei Kolomenski
