Class Tessellate

java.lang.Object

org.openscience.cdk.geometry.surface.Tessellate

public class Tessellate
extends Object

Performs a tessellation of the unit sphere. This class generates the coordinates of the triangles that will tessellate the unit sphere. The algorithm is recursive subdivision of an initial representation which can be tetrahedral, octahedral or icosahedral. The default is icosahedral. The number of points generated depends on the level of subdivision. The default is 4 levels and with the initial icosahedral representation this gives 1536 points.

The constants for the tetrahedral and icosahedral representations were taken from http://eeg.sourceforge.net/eegdoc/eeg_toolbox/sphere_tri.html
