I am attempting to render a 1600x1200 AA 0.3 version of a level 5 Menger
Sponge. However, it will crash with a "POV-Ray for Windows has encountered
an error" message after about two minutes, occasionally. And, when it does
appear to parse correctly, there is no render window and the statistics say
that the entire four minutes was spent on render time. I check the folder
and find a 640x480 bitmap file, which is not what I wanted. It will also
crash for me if I try 800x600 no AA. I run Windows XP Home with POV-Ray
3.6.
//BEGIN POV FILE
//The method I'm using to do this is this: create a 3x3 block of cubes, then
comment out
//the appropriate cubes to remove. This creates the Menger Sponge. Most of
this POV file
//is just a bunch of declarations, and in the end, there will only be about
one object.
