[vtk-developers] New nonlinear celltypes

[Soeren Gebbert]

Dear developers,
i have developed new nonlinear celltypes. The company im working in and i
have decided to contribute this code to VTK. Im working with the VTK 5.0
branch
at Linux 32Bit Suse 8.0, 9.2 and windows XP.

I have attached an overview of the new celltypes.
One file shows the description of the implementation status for each new
celltype and the status of changes
in the VTK Filtering and Graphics classes. The other file shows figures
(like in the VTK books) of the
new celltypes with numbering and the names in vtkCellType.h.

Because i have integrated these new cells into VTK 5.0, there are some
changes in other VTK classes i want to provide too.
I have written a small interacive testprogramm, to test the abilities of
the new celltypes, like contouring, clipping,  tessellation  (with
modiefied bridge dataset), picking and so on. We are working with these
cells for a while, and it seems they are working very well.
But i was not able to test every functionality of the cells (take a look
at the implementation status).

If you are interested, please tell me to who i can send the following files:
1. Sources of the new celltypes
2. The small interactive testprogramm with modified Bridge dataset (for
tessellation)
3. The diffs of all VTK classes i had to modify
4. The documentation, with:
    - figures of the cells (openoffice format)
    - implementation status (openoffice format)
    - Gnuplot files with shape functions (for 2D cells only ;) )
    - VTK Dataset for each new cell

I tried to fulfil the the contribution rules (copyright and stuff) and
the coding standart of VTK.

If you have any question or suggestions, feel free to contact me.

Best regards
Soeren Gebbert
