Hi Thomas,

first of all: great work !
I had a SHORT look into your code and stumbled about a minor problem:

quote:
#while (Counter < Numbers)

  #local Scaling = 1.0;
  #if (Counter < Numbers*0.33) #local Scaling = 1.50; #end
  #if (Counter < Numbers*0.66) #local Scaling = 1.25; #end

:endquote
Scaling == 1.50 is NEVER used, because if the counter is less than 0.33*Numbers,
it is also less than 0.66*Numbers, and then the second line sets Scaling == 1.25
!
These two lines have to be swapped or #elseif has to be used in the second line
for the desired effect!

Sorry ;-)

Sadly I'm involved with too many other projects at the moment (most of them NOT
raytracing-related) to play around with this...

Greetings
Karl

Oops! You are perfectly right. I did not think this through correctly.

That's all right :-) I tend to get blind to my own errors at some stage.

Understandable. No problem.

Here is the corrected version. Thanks again, Karl.
