Classes:

• AttractorPolygonReduction: Abstract base class for all attractor reduction chisels. Attractor polygon reduction chisels use one IFS (the attractor) to reduce a second IFS (the floater). It does this by warping the first IFS onto the second. The result has the same basic polygon count as the first IFS, but the same shape as the second IFS. Actually, the resulting polygon count is the same as triangulating all faces of the attractor IFS by placing a vertex in the center of the face and connecting it to the surrounding vertices. The reduction takes place in two phases. First, the floater IFS is partitioned into sets of coordinates. ...
• SpaceStructureBuilder: The SpaceStructureBuilder is a Chisel which loads information from a VRML file into a SpaceStructureLoader. It is used like a function call to a ChiselEngine, telling the chisel engine to chisel a file using the SpaceStructureBuilder, the end result is a SpaceStructureLoader filled in the all the SpaceStructures of the file.
• AttractorSelector: The AttractorSelector or one of its subclasses is created by the CoordAttractor factory method "createAttractorSelector". It is used to track the currently selected attractor as a floater is matched one by one to each attractor. Subclasses handle marking of the preserved floaters in each attracted floater set.
• FaceGenEnumerator: The FaceGenEnumerator is an Enumeration which returns FaceGenerator objects. Each FaceGenerator can be used to generate a subset of the coordIndex values for an IFS reduced by the AttractorReductionAlgorithm. This object is returned by AttractorReductionAlgorithm.enumerateFaces.
• FaceGenerator: The FaceGenerator generates a set of triangles based on a face from the original attractor and its dual. The triangles are two points from the attractor face edge, and the one dual point in the middle of the attractor face.
• LODAttractor: Attractor polygon reduction chisel which works with two level LOD nodes. The low resolution IFS is used as an attractor to reduce the high resolution IFS, then the result is used to replace the high resolution IFS.
• CoordAttractor: The CoordAttractor attracts one set of coordinates to a second set. The end result creates a set of floater coordinates for each attractor coordinates.
• GeodesicAttractor: Attractor polygon reduction chisel which generates a geodesic dome to use as the attractor. Options: frequency of dome
• FarPreservingAttractorSelector: The FarPreservingAttractorSelector marks for preservation the farthest floater in the attracted floater set.
• NearPreservingAttractorSelector: The NearPreservingAttractorSelector marks for preservation the nearest floater in the attracted floater set.
• FarPreservingCoordAttractor: The FarPreservingCoordAttractor is a CoordAttractor that marks the farthest floater in the attracted set.
• NearPreservingCoordAttractor: The NearPreservingCoordAttractor is a CoordAttractor that marks the nearest floater in the attracted set.
• AttractorReductionAlgorithm: The attractor based polygon reduction algorithm.
