dna_viewer_run_in_maya.py

"""
This example demonstrates Maya UI Window for simple and non-programmatic creation the scene with the creating functional rig.
- usage in command line:
    - call without arguments:
        - will not start with error message: "DNAViewer needs to be run with Maya2022"
    NOTE: Script cannot be called with Python or mayapy, it' must be called in Maya Script Editor.
- usage in Maya:
    1. copy whole content of this file to Maya Script Editor
    2. change value of ROOT_DIR to absolute path of dna_calibration, e.g. `c:/dna_calibration` in Windows or `/home/user/dna_calibration`. Important:
    Use `/` (forward slash), because Maya uses forward slashes in path.

    Expected: Maya will show UI.

NOTE: If running on Linux, please make sure to append the LD_LIBRARY_PATH with absolute path to the lib/linux directory before running the example:
    export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:<path-to-lib-linux-dir>
