Ah, I knew you had a big hand in rand.inc, didn't know about (or at
perhaps remember... the histogram macro) :-). Suppose the need has been
around a long time too. I'd for years been using external tools, but a
few days ago I decided to code up something which better aligned with
what I wanted - all POV-Ray.
And Bill W., Thanks again for mentioning the histogram macro - it got me
thinking and I've finished now a couple re-writes and have one slightly
faster than an all SDL one, but both run in a few seconds as a rule. My
updated code will be part of the next, published povr fork tarball.
It's interesting what you see on cranking up the bin and sample counts.
Attached an image using 1 million samples and 8192 bins - some of the
quirks start to show (again wrinkles, noise generator 3) - though doubt
they matter too much practically.
Bill P.
