I am working on fence violation. A tracking device sends a series of co-ords, out of this I need to create a fence with buffer.
I use shapely library for this.
from shapely.geometry import LineString
coords = [((12.898208,80.227798),(12.811857,80.228433),(12.794150,80.222705),...)]
multilines = MultiLineString(coords)
poly = multilines.buffer(1)
Now I want to store this polygon as a MongoDB GeoJson and for every point I receive from the tracker device, I want to check a $within query on Mongo.
Is there any way to convert this polygon into a bounding box, iterate all the points and create a geoJson object to store inside Mongodb. Is there any other better option?
I did not read the manual carefully. After some time I found that
boundbox = list(poly.exterior.coords)
returns what I wanted.

I am trying to find a good 3D geometry library for Python that has similar operations and functionality to Shapely.
http://toblerity.org/shapely/manual.html
Shapely is great, and has exactly what I need, especially around the creation and manipulation of Linestring objects. Unfortunately, it only supports operations on 2D objects, even though 3D points can be created.
Does anybody know of any a similar module that operates in full 3D? It would be greatly appreciated. Thanks.
Have a look at Pymesh:
http://pymesh.readthedocs.io/en/latest/
Its a new CSG wrapper for basic 3d geometry applications.
Is that the type of thing you're looking for?
Have a look at d3g package in PyPI.
Visit https://pypi.org/project/d3g
pip install d3g

I've recently been making many types of maps and graphs using Python.
All of the maps were made inside of matplotlib with Basemap, which has the dependencies of GEOS and Proj4. I'm making these for a professor that I'm working for at my university.
I am not entirely sure of the proper way to give credit to the software that was used to generate these in case any of the graphics I've been making get put into a publication.
What is the appropriate way to cite software?

I want to find area of latitude/longitude bounding box in square meters.
I need to do this quickly, that's why the solution should be offline.
I usually use Shapely for this kind of tasks.
However... this particular problem is not as easy as it looks, since you would need to transform your lat/lon data to a more appropriate projection.
You can use pyproj for that.

I am having issues selecting all of the bindpose nodes in a scene.
How can I get them?
I am using PyMEL for this particular script.
use
pm.ls( type = 'dagPose')
to get all of the pose nodes in the scene. Then loop through those and check the .bindpose attribute to see if the pose node is a dag pose.
all_poses = pm.ls(type = 'dagPose') or []
bind_poses = [k for k in all_poses if k.bindPose.get()]

Is it possible to make 2D games using python? If it is got any links to any 2D game that used Python to create it? I was thinking of learning Python but thought i should ask you guys if it can create 2D games before I do start.
Yes, check out http://pygame.org
It's a pretty popular 2D library for Python.
I use pygame myself and it is very good. It has good documentation and tutorials, and is quite well designed. I've also heard wonderful reviews of pyglet.
