To the issues of JAVA performance:
I have compiled both original version (Ray) and this optimized version
(RayTracing):

> <URL:http://www.infimum.dk/privat/RayTracing.java>

with the JET compiler (http://www.excelsior-usa.com/jet.html)
and got the following results (in CPU secs):

RAY: JVM EXE
input = 100 12,4 5,2 =39%
200 39,7 19,0 =48%
300 84,3 42,8 =51%

RAYTRACING: JVM EXE
input = 100 7,6 4,0 =52%
200 28,2 13,8 =49%
300 64,9 30,4 =46%

Percentage shows the ratio of compiled and optimized native code speed
vs. JVM speed. What is interesting: a better written source code is
better optimized by a compiler -- see that increasing the job size
takes less and less time in the optimized program...

Ah, yep, this was about another way to accelerate your program ;)
