[GRASS-dev] 3D Vector to Voxel

[Benjamin Ducke]

That looks really useful. There is probably a myriad of other
classes in VTK that could be used by GRASS modules, too.

I guess the best way would be to write some add-on
modules that depend on VTK and the GRASS bridge and
expose some VTK classes to the GRASS CLI.

However, then I would have to learn C++ ;)

How about the OpenGL coordinate precision problem?

Have a look at the vtkVoxelModeller class :
http://www.vtk.org/doc/release/5.4/html/a01861.html

or the vtkImplicitModeller class:
http://www.vtk.org/doc/release/5.4/html/a00859.html

Booth classes convert arbitrary datasets to a voxel representations.

I have just committed a grass vector topology reader to the vtkGRASSBridge
repository.
Maybe you can now create voxel representations of 3d grass vector
data, using GRAS, VTK and vtkGRASSBridge?

Best regards
Soeren
