Yes, Bill, that would be fine indeed.

It's about 60mb. One mesh2, #declared as 'lucy'. Enjoy!

Thanks Bill, quick to download too. :-D

I thought I'd give this a go - I grabbed the PLY file of Lucy and wrote a few
lines of Smalltalk to convert into a mesh2 file - took about 30 minutes. Flat
polygons, but, as Bill said, they're probably going to be sub-pixel anyway.
But. But... The resulting file (with 5 decimal places of accuracy) is 1.2GB in
size, and when I tried to render it on my 4GB MacBook Pro, POV took about 3.8GB
of Virtual Memory, which nowhere near fitted into the 2.3GB of free RAM I had
after the OS and file buffers took their slices. I left it trying to parse the
file for about 50 minutes then just gave up.
I might give it a go on an AWS EC2 cloud instance - it's US$0.68 per hour for a
8 CPU/7G RAM/64 Bit machine. But I've still got to get a 1.2GB file onto it!
I'm *not* going to give anyone the file, but you welcome to take the code and
run it yourself in Pharo 1.2 (a Smalltalk development environment). You *will*
need a 6GB, 8GB or greater machine to use the mesh2 though!
Cheers,
Edouard.

What might be of help, if you can do it, is to simplify the model. Using
a trial version of 3DS Max I reduced the vertex count to 20% of the
original (28 Meg, 9 Meg zipped)

Thanks but it is the bog standard marble. It is backlit and that makes a
difference. :-)
I think I'll try Lucy with the material map I used for the Buddha.

And here it is. I've created another simplified mesh using 10% of the
vertexes (14 Meg zipped to 5 Meg). It messes up my big idea of
mm_per_unit though.
I don't mind sharing it even though 3DS Max says the mesh is a rats nest.

Here's my little attempt. Rendered in 10mins, without aa though. One thing I've
noticed is that I get a large number of bright single-pixel artifacts unless I
use large sample counts (using 1000,100 here), even when also using aa. Is there
any way to avoid this, or is it just the nature of the beast?
