surfaceVoronoi: Computes the voronoi diagram of points in a curved surface.

In tunelipt/model3d: Funções para manipulação de modelos 3D.

Description

Computing voronoi diagrams for 2D points is simple if libraries are available. If the points are contrained in a curved 3D surface, things are a little more complicated. This function projects the surface on a plane computes the voronoi diagram in this plane and then projects the resulting polygons back to 3D.

Usage

  surfaceVoronoi(m, pts, basefun = getBase,
    ptsnames = NULL)

Arguments

m	Polygonal 3D mesh.
x	X Coordinate of the points that will be used to compute the Voronoi diagram
y	Y Coordinate of the points that will be used to compute the Voronoi diagram
z	Z Coordinate of the points that will be used to compute the Voronoi diagram
pnames	Names of each point.
basefun	Function used to obtain the projection plane.
ptsnames	Names of the points.

Value

A list containing 3D polygonal meshes of the influence area for each node.
