Application
    surfaceMeshConvertTesting
 
Description
    Converts from one surface mesh format to another, but primarily
    used for testing functionality.
 
Usage
    - surfaceMeshConvertTesting inputFile outputFile [OPTION]
 
    \param -clean \n
    Perform some surface checking/cleanup on the input surface
 
    \param -orient \n
    Check face orientation on the input surface
 
    \param -scale <scale> \n
    Specify a scaling factor for writing the files
 
    \param -triSurface \n
    Use triSurface library for input/output
 
    \param -keyed \n
    Use keyedSurface for input/output
 
Note
    The filename extensions are used to determine the file format type.
