A friend of mine was raving about how good
Poser6 was. So I bought a copy.
I have gotten a prototype to export from Poser6 to basic Lego outline.
Most of this was just getting the model into a format that could be used in the
manner that I described for the Stanford Bunny. This would then allow instructions to be
generated.
The real problem was dealing with the fact that the poser models are in general
not watertight. This causes some problems with CSG operations, but this can be
dealt with.
I used the rib file export. I filtered out the ground and camera. The rest of
the triangles I arranged into povray mesh2 format. I declared this mesh2 as a
macro with the inside_vector as a parameter of the macro.
#macro MeshObject(outsideVector)
mesh2 {
vertex_vectors {
...
}
face_indices {
...
}
inside_vector outsideVector
}
#end

This then allows the macro to be used in several overlapping copies to deal with
the holes in the model:
...
union
{
intersection
{
MeshObject(<0,0,1>)
MeshObject(<0,0,-1>)
}
intersection
{
MeshObject(<0,1,0>)
MeshObject(<0,-1,0>)
}
intersection
{
MeshObject(<1,0,0>)
MeshObject(<-1,0,0>)
}
}
...

This seems to work filling in the holes in the model. It does slow down the
rendering a lot, but is necessary.
Then slices are rendered through the model as described in the bunny document
(using the above union in the bunny’s intersect block). These slices are shrunk
down to the correct size, and then each pixel is interpreted as a 1x1 brick.
This output could then be passed to the
filling software, but a friend says that he would prefer just to fill in the
outlines by hand.
The results appear good.
Important Note: I am not a lawyer. I don’t know about the licensing issues
associated with the Poser models. There may be issues using these in sculptures
for sale. Is this a “still image” or a “simplification”?
