Class ModelCollapseRecord

  • public class ModelCollapseRecord
extends java.lang.Object
    A simple triangle mesh that represents a level surface. The mesh only stores vertex positions and vertex normals. The surface viewer creates a Shape3D object whose geometry is an object from ModelTriangleMesh. The surface color is provided by attaching to the Shape3D object an appearance that contains a material. The vertex normals in ModelTriangleMesh are used by the lighting system in conjunction with the surface material to produce the surface color.

      • ModelCollapseRecord

        public ModelCollapseRecord()
        The default constructor is used by ModelClodMesh for creating a record before loading its data from disk. It is also used by the class ModelSurfaceDecimator for creating records that need to be initialized from other records already created during the edge collapse process.

      • ModelCollapseRecord

        public ModelCollapseRecord​(int iVKeep,
                           int iVThrow,
                           int iVQuantity,
                           int iTQuantity)
        This constructor is only used by the class ModelSurfaceDecimator for creating records from edge collapse data during the edge collapse process.
        Parameters:
        iVKeep - the index for the vertex to be kept during an edge collapse
        iVThrow - the index for the vertex to be thrown away during an edge collapse
        iVQuantity - the number of vertices that are deleted from the mesh because of the collapse of edge
        iTQuantity - the number of triangles that are deleted from the mesh because of the collapse of edge
