CircPacker is an application software in Python 3 to create circle packing
in closed polygons.
- Free software: BSD-2-Clause.
- Documentation: https://circpacker.readthedocs.io.
The code was written in Python 3. The packages numpy,
scipy, matplotlib
and triangle are
required for using circpacker. All of them are
downloadable from the PyPI repository by opening a terminal and typing the
following code lines:
pip install numpy pip install scipy pip install matplotlib pip install triangle
To install circpacker open a terminal and type:
pip install circpacker
To produce the plot shown above execute the following script
from numpy import array
from circpacker.basegeom import Polygon
from circpacker.packer import CircPacking as cp
coordinates = array([[1, 1], [2, 5], [4.5, 6], [8, 3], [7, 1],
[4, 0]])
polygon = Polygon(coordinates)
boundCoords = polygon.boundCoords
CircPack = cp(boundCoords, depth=10)
CircPack.plot(plotTriMesh=True)
Now, let's see an example for a autosimilar bimsoil model.
from numpy import array import matplotlib.pyplot as plt from circpacker.basegeom import Polygon from circpacker.packer import CircPacking as cp from circpacker.slopegeometry import AnthropicSlope h = 15 # slope height slopeGeometry = AnthropicSlope(h, [1, 1.5], 2/3*h, 2/3*h, 1/3*h) boundCoords = slopeGeometry.boundCoords polygon = Polygon(boundCoords) CircPack = cp(boundCoords, minAngle=20, maxArea=0.35*polygon.area, length=0.05*h) CircPack.plot(plotTriMesh=True)
For a simple slope with h=15 m, inclination H:V of 1:1.5, crown and foot lengths of 2/3h, and depth 1/3h. Minimum angle and maximum area for each Delaunay triangle of 20° and 35% of slope area, respectively.
Here is a list of papers based on circpacker.
