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
Implementation Issues
- VTK File formats and IO
- XML formats
- Legacy formats
- Geometry Filter
- Critical filters
- Contouring
- Clipping
- Search (vtkDataSet::FindCell and FindPoint)
