I am working on a spherical light, so far it looks something like this:
#declare STEP=0.2;
#declare M=-1;
#while (M<=1)
#declare N=-1;
#while (N<=1)
#declare O=-1;
#while (O<=1)
#if ( (M*M+N*N+O*O) <= 1 )
light_source
{
< M, N, O> color White/DIVISOR
}
#end
#declare O=O+STEP;
#end
#declare N=N+STEP;
#end
#declare M=M+STEP;
#end
Only problem is, I don't know what to set DIVISOR to, in order for the
overall brightness to equal that of a single light_source. I know it has
something to do with the volume of a sphere, and the value of STEP. Does
anyone know what formula to use?
