Dyna3D

(work in progress)

A JAVA package to generate dynamic Delaunay triangulations in 3D. The package is very robust and allows dynamic insertion, movement and deletion of vertices. Each vertex can easily be associated with a user object. Currently, there is no documentation available, just a few words about usage (this is a 3D Delaunay package, hence the positions should be given as 3-element arrays of doubles):

• Start by instantiating an object of the class SpaceNode<T>, where T is the user object you want to associate with it. (public SpaceNode(double[] position, T content)). This will be the first vertex in your simulation. (Let's call it A)

• Add new nodes to the simulation by using the function
  public SpatialOrganizationNode<T> getNewInstance(double[] position, T userObject) on any node that is already part of the triangulation, i.e. A.getNewInstance(). A PositionNotAllowedException will be thrown if you're trying to place a node at the exact same place as another node in the triangulation.

• SpaceNode implements the interface SpatialOrganizationNode. Look at the interface to find out about more functions of the triangulation, like moving vertices (SpaceNode.moveFrom(double[] delta) - “delta” is the movement vector) or removing vertices.

• Contact the author if you find bugs or have any problems (you'll find the email-address under http://www.ini.phys.ethz.ch/people/dennis) or wait for updates.
