[Radiance-general] rpict, rtrace start up time and number of sources

[Lars O. Grobe]

Hi Greg,

thank you for that whole bunch of information! ;-) I have no redirecting 
surfaces, but I use (mk)illums to bundle groups of light sources for the 
indirect calculation. I do not know if this causes additional start-up 
processing.

The idea to deactivate the obstruction cache is quite promising for my 
case. I have one illuminated room, so all those light sources are not 
hidden by surfaces any way. That means that all that caching is for 
nothing and just wastes the start-up time in this special scenario.

I will try this as soon as the next image is done (I guess tomorrow) and 
report any success.

The idea to use -P is a good one - but I wonder how to do this when 
using ranimate to control the rendering. Maybe you remember, I am that 
crazy guy using ranimate to render stills - which is nice cause I can 
use it to continue after broken processes, distribute processes both on 
smp and on clusters, and all that... ;-) I will have a look at the 
ranimate documentation once again.

CU and thanks, Lars.
