I'm using floowing radiosity, but seems not to load data, because
- render time is same
- when I delete file "rad4" or type invalid name like "asdfasdf" - pov
doesn't even show a warning
radiosity {
pretrace_start 1/12
pretrace_end 1/(12*8)
count 1200
nearest_count 9
error_bound 0.45
recursion_limit 9
low_error_factor .32
gray_threshold 0.0
minimum_reuse 0.002
brightness 1
adc_bailout 0.01/2
normal yes
media no
// save_file "rad4"
load_file "rad4"
always_sample 0
max_sample 3
#declare AMBIENT_DEF=0;
}
rad4 is a file created in same scene, using same radiosity but with :
save_file "rad4"
// load_file "rad4"
// always_sample 0

#macro g(U,V)(.4*abs(sin(9*sqrt(pow(x-U,2)+pow(y-V,2))))*pow(1-min(1,(sqrt(
pow(x-U,2)+pow(y-V,2))*.3)),2)+.9)#end#macro p(c)#if(c>1)#local l=mod(c,100
);g(2*div(l,10)-8,2*mod(l,10)-8)*p(div(c,100))#else 1#end#end light_source{
y 2}sphere{z*20 9pigment{function{p(26252423)*p(36455644)*p(66656463)}}}//M

1. You can set pretrace_start and -end to 1 if you're loading data
2. Rendering isn't faster, but without pretrace and always_sample
POV doesn't need to parse the entire Radiosity-Data once again.
