Application
    surfaceConvert
 
Description
    Converts from one surface mesh format to another.
 
Usage
    \b surfaceConvert inputFile outputFile [OPTION]
 
    Options:
      - \par -clean
        Perform some surface checking/cleanup on the input surface
 
      - \par -scale <scale>
        Specify a scaling factor for writing the files
 
      - \par -group
        Orders faces by region
 
    Note
        The filename extensions are used to determine the file format type.
