grid_plot.m

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
