Emma:
We have an optoTOP-HE scanner here in Kansas City, and we use
optoCAT software, but I don't recall a ".ply" output option. I suspect
your version of the software is more recent than our 2003 version (which
is limited to .bre, .stl, and .wrl formats). For measurement, we use
STL surfaces and amira software. So far, we've had no problems with
optoCAT (other than limited documentation, which leads to a lot of
trial-and-error on our part). Have you tried other formats?
There are actually two optoTOPs here. The other is literally
down the street, in the sculpture department at Hallmark cards (where it
is used by their people who design Christmas ornaments). I could check
with the people over there to see if they use ply files.
We would be interested in hearing about how you are using your
Breuckmann scanner, especially if you are scanning translucent
materials, like tooth enamel or dentin.

Subject: OptoCAT 3D scanning software and .ply files
Dear Morphometricians,
I am working on a 3D scanner system called OptoSCAN developed by
Breuckmann, Meersburg Germany. Firstly, I would appreciate any contact
with people who have used/are currently using one of these systems.
The software that comes with the system is called OptoCAT, and once
merging all the single images into a 3D dataset, the output file is a
.ply file (polygon file format). I understand that .ply files come in
binary - little endian 1.0 format, and ASCII 1.0 format. The OptoCAT
application exports in binary format, and these .ply files crash my .ply
viewer (SunXi viewer) and the Landmark application (developed by the
Institute for Data Analysis and Visualization (IDAV)) that apparently
reads .ply files.
Has anyone got experience working in 3D, specifically with .ply files.
Or has anyone used this OptoCAT software?
Suggestions please!
Thanks,
