Collada format is used by Apple's iBooks Author program to embed 3D
graphics. Collada files, with .dae extension, can also be displayed in
Apple's Preview application.
I don't believe Collada is at all related to PDF, which uses U3D format
for 3D data. MeshLab is supposed to read many data formats, including
Collada, and generate U3D output. Unfortunately, Chimera Collada output
is not read properly by MeshLab; triangle per-vertex colors, specified
as an RGBA data source, seem to be ignored. Worse, saving U3D output
(so at least we get the geometric shape) also fails, producing, from
Chimera's 28MB Collada file, 2 1KB files (no, I don't think it's due to
compression :-) ).
The bottom line is that I do not have anything new to contribute on the
PDF front. Sorry.
