PyGEOMETRY

Python Geometry Library

Currently contains the following functions:

• angle_box_2d
• angle_contains_ray_2d
• angle_deg_2d
• angle_half_2d
• angle_rad_2d
• angle_rad_3d
• angle_rad_nd
• angle_turn_2d
• anglei_deg_2d
• anglei_rad_2d
• annulus_area_2d
• annulus_sector_area_2d
• annulus_sector_centroid_2d
• ball_unit_sample_2d
• ball_unit_sample_3d
• ball_unit_sample_nd
• basis_map_3d
• box_01_contains_point_2d
• box_01_contains_point_nd
• box_contains_point_2d
• box_contains_point_nd
• polygon_contains_point_2d
• polygon_contains_point_2d_2
• sphere_distance1
• sphere_distance2
• sphere_distance3

Python bridge to this excellent library:

http://people.sc.fsu.edu/~jburkardt/c_src/geometry/geometry.html

only provides the functions described in the geometryexterns.hpp file so far.

In answer to this stackoverflow question, and for fun :)

Build Instructions

clone me, then:

gcc -c -fPIC geometry.cpp -o geometry.o
gcc -shared -Wl,-soname,libgeometry.so -o libgeometry.so  geometry.o

Then you can do:

python geometry.py

Notes

Switched to using the C version of GEOMETRY so that we don't have to write externs
