Hello,

I am experiment with a java Programm which can create a 3D-Model from a DICOM File (is the result which you get from an ct or mrt). I read a lot now of the stl format on the web, but i couldn't found out how to calculate the normal vectors for each triangle. The ascii formate of a triangle in stl is:
facet normal Ni Nj Nk
    outer loop
        vertex vx vy vz
        vertex vx vy vz
        vertex vx vy vz
    endloop
endfacet

My Question is how to calculate Ni, Nj and Nk.

I hope someone can help me

DICOM: The Digital Imaging and Communications in Medicine (DICOM) standard for distributing and viewing any kind of medical image regardless of the origin

Have you posted the software to convert DICOM?

I think it would be a great contribution, as many medical facilities start using 3d printers they will want to experiment, and learn about the technology. Your code could make the learning curve shorter, or offer a solution that is unique for their application.
Tks!
