I'm not too sure what is resonable for render times with a lot of reflection
and refraction. I had the following in my .pov file :
global_settings { assumed_gamma 2.2
max_trace_level 20
max_intersections 128
ambient_light color <0.7, 0.7, 0.7> }
The following image is taken from a 8192x6160 render thus :
$ time -p /usr/local/povray31/povray_sparc_v9a -I./input/tet5.pov \
> -L/usr/local/povray31/include +W8192 +H6160 +V +X8192 +B4096 \
> +FT +O./tet5_8192x6160.tga +HTT +HN./tet5_cpu_8192x6160.tga +Q9 \
> +A0.3 +AM2 +R3 +GA +KC +K0.382
