Add octomap python package.

[zbynekwinkler]

The whl package on osgar.robotika.cz was fixed to include proper RPATH. For details
see https://github.com/wkentaro/octomap-python/ repository issue no. 1.

To run the included example install also the follwing packages:

  pip install glooye imgviz trimesh scipy networkx

---

I have not done much yet with it. I've just now made it run the one example.

No. But feel free to try pip install octomap-python. I created this branch because pypi install didn't work out of the box on linux. I have not started my windows computer for several months now.

OK, thanks - I tried the original package too (on Win10), but it wanted to be built with MS Visual Studio -> FAILED on my machine, so I switched to manual decoding ... I may try it on linux later today, thanks.

the octomap-python package seems to give me first hints ...

>>> tree = octomap.OcTree(0.1)

>>> tree.insertPointCloud(np.array([(0.01, 0.01, 0.01)]), np.array((0, 0, 0), dtype=float))
>>> tree.volume()
0.0010000000000000002

>>> for line in tree.writeBinary().split(b'\n'):
...   print(line)
...
b'# Octomap OcTree binary file'
b'# (feel free to add / change comments, but leave the first line as it is!)'
b'#'
b'id OcTree'
b'size 17'
b'res 0.1'
b'data'
b'\x00\xc0\x03\x00\x03\x00\x03\x00\x03\x00\x03\x00\x03\x00\x03\x00\x03\x00\x03\x00\x03\x00\x03\x00\x03\x00\x03\x00\x03\x00\x02\x00'
