Class ModelCollapseRecord

java.lang.Object
gov.nih.mipav.view.renderer.J3D.model.structures.ModelCollapseRecord
public class ModelCollapseRecord extends 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 invalid input: '<'VKeep,VThrow>
      iTQuantity - the number of triangles that are deleted from the mesh because of the collapse of edge invalid input: '<'VKeep,VThrow>

      Parameters:
      kIn - the file from which the records are loaded
      Throws:
      IOException - if the there is an error reading from the file

    • print

      public void print(PrintWriter kOut) throws IOException
      Support for saving the collapse records to a text file. This function is called by ModelClodMesh.print(PrintWriter).
      Parameters:
      kOut - the file to which the records are saved
      Throws:
      IOException - if the there is an error writing to the file

    • save

      public void save(RandomAccessFile kOut) throws IOException
      Support for saving the collapse records to a binary file. This function is called by ModelClodMesh.save(RandomAccessFile).
      Parameters:
      kOut - the file to which the records are saved
      Throws:
      IOException - if the there is an error writing to the file
