Goals:

  • Add support for arbitrary polyhedral cell (manifold, watertight, may be concave)
  • Develop smooth interpolation functions for polyhedron
  • Create filters, examples and testing infrastructure supporting this technology


Summary of Implementation Plan:

  • Identify interpolation functions
    • Mean Value Coordinates (paper by Tao Ju et al.)
    • For triangle meshes as well as arbitrary polyhedron
  • Implement interpolation functions & filters
    • vtkMeanValueCoordinatesInterpolator
    • vtkProbePolyhedron
    • vtkDeformPointSet
  • Polyhedron cell support
    • vtkPolyhedron - more complex cell in that it requires explicit face representation
    • vtkUnstructuredGrid - modified to support polyhedron cell, new InsertNextCell() and related methods
    • vtkGenericCell expanded to include vtkPolyhedron
    • vtkCellTypes.h has new #define VTK_POLYHEDRON
