Decrease variance and increase confidence.
The number of samples you supply is the *maximum* number POV-Ray will
shoot. However, to speed things up, it employs some statistics.
Confidence shows how 'confident' POV-Ray should be that the result is
smooth before it stops shooting rays, and is a value from 0 to 1
representing 0% to 100%. Variance shows how little the next samples
should be expected to contribute to the smoothness before POV-Ray
stops shooting rays, and is a positive value, the lower, the better.
Try this out, slowly increasing the amount of Focal_Blur_Accuracy
until you get a satisfying result. Use the macro instead of specifying
confidence and variance, as in:
#macro Focal_Blur_Accuracy (FB_Accuracy)
confidence 1-pow(10,-FB_Accuracy)
variance pow(10,-FB_Accuracy-2)
#end
camera {
[something]
Focal_Blur_Accuracy(1)
}
See if it helps any. Also, try Francois' Automatic DOF macro on
www.wozzeck.net .
Good luck.
