Hello all...

the last two days, I wrote a patch for UNIX POVRay-3.6. to speed 
up user-functions as used e.g. in isosurfaces. 

Instead of interpreting the functions as done by the POV VM, this 
patch does just-in-time compilation of the function using the system 
compiler -- all that on-the-fly completely transparent for the user. 

Result: Some scenes trace 4 times as fast!

Disclaimer: 
- The patch is Linux-specific. Probably Minor efford porting to other UNICes 

- The patch is _highly_experimental_. It works fine for me but I expect that 

- The patch is not cleanly designed in several points. Unfortunately, during 


Any comments welcome.
