Class CollapseRecord

java.lang.Object
  com.jme.scene.lod.CollapseRecord

public class CollapseRecord

extends java.lang.Object

CollapseRecord originally ported from David Eberly's c++, modifications and enhancements made from there.

This class keeps an array of vertex index positions that are to be collapsed. It is used to modify ClodMesh objects so that they contain less information.

Field Detail

vertToKeep

public int vertToKeep

An int index in the Mesh's vertex array. It is the vertex assigned from the indices array. Used in collapsing the mesh.

vertToThrow

public int vertToThrow

An int index in the Mesh's vertex array. It is the vertex assigned from the indices array. Used in expanding the mesh.

numbVerts

public int numbVerts

numbTriangles

public int numbTriangles

The number of triangles in the Mesh after edge collapse.

numbIndices

public int numbIndices

Lenght of this indices array.

indices

public int[] indices

An integer value in the Mesh's indices array referencing a vertex to keep or throw.

Constructor Detail

CollapseRecord

public CollapseRecord(int toKeep,
                      int toThrow,
                      int vertQuantity,
                      int triQuantity)

Creates a new CollapseRecord.

Parameters:

toKeep - The vertex index that is kept.

toThrow - The vertex index that is thrown.

vertQuantity - The new vertex quantity of the mesh using this record.

triQuantity - The new triangle quantity of the mesh using this record.

CollapseRecord

public CollapseRecord()

Creates a new collapse record with all values at their default.
