[Radiance-general] Re: graphing radiance raytrace paths

[Gregory J. Ward]

Hi Jelle,

Check out the "xshowtrace" command.  It uses rtrace on an image to 
superimpose ray paths you select.  It doesn't show a side-view with the 
camera in the image, unfortunately.  There's an exercise for the 
reader!

Hi,

What I would love to do is to produce a graph depicting the rays a 
radiance rendering actually consists of, moving from the camera back to 
the light source.

What would be an appropriate way of doing so? Would a radiance holodeck 
file do the trick, since from what I understood, its storing the actual 
traced rays in a file format.

The other question would be how many rays such a graph should contain, 
probably a 100k is more than sufficient for such a graph, while an 
actual radiance render would consist of many more. Looking forward 
hearing your suggestions!

 Cheers,

Jelle.
