Rendered view 13, command line: +w1024 +h768 +a0.2 +am2 +r4
Took approx 25 minutes on a P4 3.0GHz
Radiosity settings as below, other settings were the changes I recommended in
the previous post.
#declare radbri = 1.50;
radiosity{
pretrace_start 100/image_width // start pretrace at this size
pretrace_end 1/image_width // end pretrace at this size
//adaptive 1 // MegaPov 1.2.1 only
count 100 // higher -> higher quality (1..1600) [35]
nearest_count 20 // higher -> higher quality (1..10) [5]
error_bound 0.5 // higher -> smoother, less accurate [1.8]
recursion_limit 5 // how much interreflections are calculated
low_error_factor .25 // reduce error_bound during last pretrace
step
gray_threshold 0.80 // increase for weakening colors (0..1) [0]
minimum_reuse 0.0015 // reuse of old radiosity samples [0.015]
brightness radbri // brightness of radiosity effects (0..1) [1]
adc_bailout 0.01
//save_file "povworld.rad"
always_sample off // turn sampling in final trace off [on]
}
Note that there are artifacts in the corners that can be corrected by boosting
count, but I didn't want to wait for it. Perhaps MegaPov's adaptive error
bound could help here also, but I've never had much luck with it. I am still
experimenting with view 0, but I expect the settings to be similar. The main
difficulty that I am encountering is that some of the windowsills that have the
interior diffuse settings receive direct light, and as a result are brighter
than they should be.
