java.lang.Objectde.jreality.geometry.SphereUtility
public class SphereUtility
Static methods for generating approximations to spheres. The approximations are based
either on subdividing a cube, or subdividing an icosahedron. These methods are used for
example in the package de.jreality.jogl for quick rendering of
spherical representations of points.
Warning: the approximation methods here have an upper limit on the fineness of the approximation which they are prepared to calculate. These limits should problably be removed.
