Meshlab looks like a pretty useful program. I'll have to take a look at that.
Just to provide options, here was my strategy:
Import into Blender
Export to .obj
Process with shell script
Export to mesh2
I'm trying to remember if I didn't need Wing3D in there somewhere for some
bizarre reason, but meshlab looks very interesting. Thanks for suggesting it.

I just played with the render again, and the white specs are reflection
artifacts from the HDR background. It must be small triangles that are rotated
just right to pull a super bright spot from the background.
As far as Meshlab, it works with the huge .ply files very well. Imports in a few
seconds.
Render time was little over an hour on an i7 quad core.

It crashes on me when trying to load Lucy (MeshLab v1.2.1 Windows
binary, run on Windows XP Pro x64 Edition), about something like 60%-70%
into the loading.

Now with proper handling for spotlights (and most other fancy classic
lighting stuff).
The other Stanford dragon.
10 minutes rendering time on an i7 QuadCore.
Stay tuned for the next beta.

I just found that PoseRay can apparently read .ply files, too. I'm just
having it take a go at Lucy right now... will take some time though >_<

The readme file of the mesh archive says that the decimated versions of the
dragon contains holes...
Maybe that is what we see as speckles

Yes it does. It is an undocumented feature since I have not tested it
completely. Also PoseRay only reads ASCII ply files. Hopefully I will
add support for binary ply files in the next release.

Well, in any case I found that it takes a looooooooooooooooooooong time
to import Lucy... (would have taken hours or so I guess; I didn't wait
that long). But I don't even now if that figure comes as binary or ASCII
ply.

I used Meshlab to convert Lucy last year to use in my ambient occlusion/ivy
generator experiments in the Sponza Atrium:

I finally got around to trying Christoph's recent SSLT mod today and thought
Lucy was a good candidate. Here are two shots using subsurface{} and radiosity.
Very promising stuff that subsurface{}
Cheers,
Rob

This looks terribly good indeed.
