def povrayExportArray(obj, camera, path, settings):
"""
This function exports data in the form of arrays of data the can be used to
reconstruct a humanoid object using some very simple POV-Ray macros. These macros
can build this data into a variety of different POV-Ray objects, including a
mesh2 object that represents the human figure much as it was displayed in MakeHuman.
These macros can also generate a union of spheres at the vertices and a union of
cylinders that follow the edges of the mesh. A parameter on the mesh2 macro can be
used to generate a slightly inflated or deflated mesh.
The generated output file always starts with a standard header, is followed by a set
of array definitions containing the object data and is ended by a standard set of
POV-Ray object definitions.
Parameters
----------
obj:
*3D object*. The object to export. This should be the humanoid object with
uv-mapping data and Face Groups defined.
camera:
*Camera object*. The camera to render from.
