Dear John and Orest(if you are here),
you wrote:

while I am (slowly) threading this route (there are also plain wrong parts of documentation, just to make out lives more interesting,
like that of medieval alchemy students) I have to use (and modify)

Dear All,
as far as I understand, now Asymptote represents triangle meshes in 3D PDF output as a special kind of NURBS surfaces.
But there are ways to store tessellated data natively in PRC,
that must be much more efficient than the current approach
(file size and viewer CPU usage considered) and will allow to attach color not to patches, but to vertexes, resulting in smooth color change.

If you are interested in recompiling the software,
you may take a look at http://www.iaas.msu.ru/tmp/u3d/u3d-1.2.852.tar.gz
I have replaced the custom build system in Intel sources with
autotools (tested on Linux and Mac) and cmake (Windows, Linux, Mac).
Comments welcome.

Any plans to have named parts in foreseeable future?.

You should use macports and let it care about package management! ;)

PRC supports polynomial curves:

There are several types of surfaces defined by curves...

Dear Jonathan,
Again - please, put the (complete!) IDTF output (may be both 1.2.1 and 1.2.0) online,
so I may try to see where the problem is (if it is converter issue).
U3D produced by Deep Exploration is also welcome.
If possible, produce a test case with less details.
Dear Paolo,
as of now diffuse colors disable lighting and shading in Adobe Reader/Acrobat,
so there is no reason...

> it believed the IDTF had only one node
it seems to be a "feature" of MeshLab, all the examples of its u3d
output posted in this forum have 1 single mesh to hold all the scene,
and, btw, your x3d output example also has everything in one mesh.
So it is "broken by design".
Any developers here to comment?.

I do not use MeshLab myself, but may be you can find the IDTFConverter program
MeshLab uses and replace it with a script that first saves the idtf file and then feeds it
to renamed IDTFConverter.
And the file is HUGE, it seems to be > 110Mb and will take a long time to convert to U3D,
may lead to converter crash and poor performance of the Acrobat/Reader 3D viewer.
Do you really...

When producing U3D MeshLab firts outputs a file in a text format (IDTF),
then compiles it into binary U3D with external IDTFConverter utility.
Please, take a look at the IDTF file with your own eyes and/or put it online
for others to inspect and see what information got out of MeshLab.
