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

[Lars O. Grobe]

I have the impression, while actual rendering time is not increasing to 
much with increasing light source counts (should be about linear in most 
scenes?), the start-up time of processes is increasing dramatically. 
What is responsible for that interesting behaviour? In a scene with some 
thousand sources, it takes three hours until rpict writes the first 
pixels (same is true for rtrace) - than it is going on fine. Is there 
anything I could do to speed up this phase of the rendering?

CU Lars.
