Spherical quadrature grid plotter. Takes a cloud of points on a sphere and plots its Voronoi tessellation.
Syntax
grid_plot(x,y,z,vorn,c,options)
Arguments
x,y,z - column vectors containing Cartesian
coordinates of grid points
c - values to be mapped into the colour
of each tessellation face, white if
this input is left empty
vorn - Voronoi tessellation; if this is not
provided, it will be computed
options.dots - the default (true) puts black
dots at centres of tessellati-
on faces
Outputs
this function plots a figure
Examples
Below is the Voronoi polyhedra diagram returned by grid_igloo(20).
