Hi Paul,

Yes, I think you're right. A level 7 Menger Sponge would probably be too
detailed for a normal screen resolution. Even the level 6 sponge is very
detailed, even at 3200x2400 resolution. But it's just for the challenge.

Just look at the tiny, little Level 0 cube in the image.
Look like a pixel error :-)

I posted the image (3200x2400, jpg, 1MB) under
povray.binaries.images, then "Menger Sponge Scene (Level 6 to 0)". Parsing time
was about 10 seconds, render time with reflection and other cubes about 3 hours.

To all: Thanks for your feedback.

Terabyte

PS: I found this on the internet: (This guy is rendering a Level 9! sponge)

--> What's procedural texturing? Could it help rendering my sponge?
