AUTHOR = "Robert E. Smith (robert.smith@florey.edu.au)";
SYNOPSIS = "Apply filter operations to meshes";
DESCRIPTION
+ "While this command has only one filter operation currently available, it "
"nevertheless presents with a comparable interface to the MRtrix3 commands "
"maskfilter and mrfilter commands.";
EXAMPLES
+ Example ("Apply a mesh smoothing filter (currently the only filter available",
"meshfilter input.vtk smooth output.vtk",
"The usage of this command may cause confusion due to the generic interface "
"despite only one filtering operation being currently available. This simple "
"example usage is therefore provided for clarity.");
ARGUMENTS
+ Argument ("input", "the input mesh file").type_file_in()
+ Argument ("filter", "the filter to apply."
"Options are: smooth").type_choice (filters)
+ Argument ("output", "the output mesh file").type_file_out();
OPTIONS
+ smooth_option;
}
