L3P is a neat little utility that will produce a ready-to-render POV-file
from any LDRAW model using any part. It is a spin-off from my L3 project.
L3P runs under DOS or in a DOS-box in Windows95/WindowsNT.
The basic idea of L3P is to take an LDraw DAT-file and generate a POV-file
1) all the triangles and quads of the model and its parts
2) automatically calculated camera and light source positions
The only remaining thing for the user to do, is to start POV-Ray.
Be sure to visit the L3P Gallery to see amazing images from ordinary .DAT
I hope you will use and enjoy L3P. Any comments are appreciated.

I'd like to say that when this was announced on the LDRAW mailing list earlier
this week, everyone has loved using this. You can quickly and easily make ray
traced images of LDRAW models. I expect a lot of images from LDRAW to be
replaced with nice ray traced versions very quickly. This is the best program
since LDRAW itself.
Holy $#&^! This is really, cool! The Ice Sat V rendering blew me
away with all the detail and the excellent way that PovRay handles
translucency, shadows, and reflections so well. I know that all of
the detail is in the .dat file, but the detail really shows up in
PovRay (edges are especially crisp).
Now all you need is some sort of option to let you draw edge lines in
the proper edge line color. This would allow the pictures to be tuned
so they look more like real LEGO instructions. Optional lines aren't
really necessary here since you can see the edges of parts with good
lighting. The Villa Roma image would look better (to me anyway) if
you could see the edge lines between the bricks which make up the
walls and the roof.
Can PovRay draw lines, or does everything have to be 3D? Can lines
have translucency? If they did, you could control the darkness of the
edge lines. It's been several releases since I've picked up the
PovRay documentation, can you tell? :-)
Are you sure the pieces are transluscent? They look like reflections
(of studs in front of the white supports) to me. I assume this could
be toned down a bit to reduce the intensity of the reflections if you
play with the material properties.

I'm stunned. It's so easy to use. First time I tried it, and it went just perfect.
No problems with my unofficial parts, no problems anyhow. Here's the result from
my first try:http://home2.swipnet.se/~w-20413/pix/lizzie.jpg
Thanks a lot, Lars!
I believe that is reflection, not translucency, although I could be wrong.
New LEGO pieces are pretty shiny, so I actually think this looks about right.

Ditto on the Stunned. This is a remarkable development. I bow to a master.
My first try was something a bit more difficult. I wanted to see if it
would choke, so I ran it on the Apache - that means the model file _and_ 35
L3P didn't miss a beat, came out perfect. WOW.
I was up till 5:00 am playing with L3P. Now if somebody can figure out a
way to make the _rest_ of POV-Ray user-friendly, I would be in heaven.

Does anyone know how hard this would be to create? Just position the camera
slightly to the left (or right), and generate another image? Or is the
positioning a very sensitive thing?
Basically, yes. It's wicked easy. The trick is to keep the center of
the image the same in both the left and right versions, and not to make
the parallax too wide or the model will look tiny.

Nope, your eyes (when viewing) are very forgiving of noise and errors!

I'm hoping some kind soul will put up a tutorial that will include how
to position the camera and lightsourcing either on the command-line or
in POV-Ray. All I would need would be standard positions like those
supported by LDraw and LDAO, I just have a hard time picturing things
in 3-dimensional space.

The white pieces are NOT transparent, but very reflective. Because of the
perfect symmetric geometry of Lego models, the reflection of the baseplate
is at the very same location that you would have seen the baseplate if you
could see through the white bricks.

Do what you can, but behave yourself.

We'll have more, right after this.
Works fine on-screen :) especially in 16- or 24-bit color.
