Hi David, AFAIK, the sources for those two programs were not touched in the Windows binary project. I don't fully understand the behavior of this program right now. I will check with Kitware to see if any changes were in fact made to that source in order to get it to work on Windows.

This time I wanted to do the conversion with rad2mgf and mgf2inv -vrml on Windows using the NREL binaries. However, the resulting files are corrupt due to bad number representations and normal descriptions. For example the description of a face in the VRML-file created with the Linux binaries is: DEF ceil_fac_001 Group { Separator { USE ceil_mat Coordinate3 { point [ -2.000000000e+00 +4.500000000e+00 +2.162119874e+00, -1.500000000e+00 +4.500000000e+00 +3.000000000e+00, -1.500000000e+00 +5.000000000e+00 +1.461123454e+00, -2.000000000e+00 +5.000000000e+00 +6.232433278e-01 ] } IndexedFaceSet { coordIndex [ 0, 1, 2, 3 ] } } } In the files created with the Windows version the same face is described as: DEF ceil_fac_001 Group { Separator { USE ceil_mat Coordinate3 { point [ -2.000000000e+000 +4.500000000e+000 +2.162119874e+, -1.500000000e+000 +4.500000000e+000 +3.000000000e+, -1.500000000e+000 +5.000000000e+000 +1.461123454e+, -2.000000000e+000 +5.000000000e+000 +6.232433278e- ] } Normal { vector [ 00 +0.000 +0.000 +0.0-1.500000000e+000 +4.500000000e+000 +3.000000000e+, 00 +0.000 +0.000 +0.0-1.500000000e+000 +5.000000000e+000 +1.461123454e+, 00 +0.000 +0.000 +0.0-2.000000000e+000 +5.000000000e+000 +6.232433278e-, 01 +0.000 +0.000 +0.000 ] } IndexedFaceSet { coordIndex [ 0, 1, 2, 3 ] normalIndex [ 0, 1, 2, 3 ] } } } Obviously, two things are corrupt: - the z-coordinates are missing their exponents - the normal vector coordinates are messed up Moreover, for me it's unclear why normal vectors are written (needed ??) in the Windows version, while they are completely missing in the Linux version. I believe that all this has something to do with de definition of VERTFMT in src/cv/mgf2inv.c #define VERTFMT "%+16.9e %+16.9e %+16.9e\n%+6.3f %+6.3f %+6.3f" Any ideas how to solve that for both platforms??
