## python efficient 3d voronoi diagram using voxels

python,voronoi,voxel
I am trying to create a Voronoi diagram using a 3d array representing voxels where the coordinates are represented by the indices of the array. For example: points = np.random.random([10,3]) vox_len = 0.1 lx = ly = lz = 11 hull_space=np.zeros([lx,ly,lz],dtype=np.int16) hull_space.fill(-1) for i in range(lx): for j in range(ly):...

## Voronoi Tessellation] Find out which point I'm referencing

d3.js,voronoi
I've got a project using this Voronoi Tessellation plugin with series of coordinates representing locations of temperature sensors - I'm thinking of using JSON to represent their locations and detected temperature values. What I need to is to display the temperature value of the sensor(point) I'm referencing to(the area where...

## Redraw plot in same window with scipy / voronoi_plot_2d

python,numpy,matplotlib,scipy,voronoi
I'm trying to make a Voronoi plot update in real time as the generating points change position. My problem is how to reuse the same figure, since currently I get a new window each time I call voronoi_plot_2d. See code: #!/usr/bin/env python import numpy as np import time from scipy.spatial...

## Constructing the 3D Voronoi Diagram from a 3D Delaunay Tessallation

3d,delaunay,voronoi,tetgen
I'm trying to convert a 3D Delaunay Tessallation (generated with TetGen) to a Voronoi Diagram. I know TetGen can create Voronoi Diagrams, but I need to perform the conversion myself due to unusual boundary conditions. I'm totally stumped with the duality here. I have two of the four: Each Delaunay...

## Summing squared area changes from Voronoi cells given area of triangles in 3D?

matlab,triangulation,voronoi,geometry-surface,finite-element-analysis
I have a list of triangles in 3D that form a surface (ie a triangulation). The structure is a deformed triangular lattice. I want to know the change in area of the deformed hexagons of the voronoi tessalation of the lattice with respect to the rest area of the undeformed...
