[Radiance-general] Sensor points visualize

[Lars O. Grobe]

Hi,

I would also do it with OpenDX. Still, another option all within Radiance:

1) pipe the point locations and the corresponding values into rcalc to 
get a falsecolor value corresponding to the photopic average and the 
location as output,

2) use awk to add the string around the numbers to translate this into 
glow (from falsecolor of photopic average) and sphere (from location, 
set radius fixed according to density and size of grid or relative to 
photopic average)

3) render using your favorite raytracer, optionally with all the scene 
geometry switched to gray (xform -m ...) using all the wonderful view 
options

Cheers,
Lars.
