[vtkusers] 3D Delaunay triangulation (vtkDelaunay3D) multithreading / multi cpu support

[kleistereimer]

hi list!

vtkDelaunay3D seems to not support multiple cores/processors by use of
multithreading. at least on my machines only one processor core is maxed
out running vtkDelaunay3D on large pointclouds.

vtk 'advertises':
"Most imaging filters are multi-threaded for parallel execution "

but this seems not true for vtkDelaunay3D. (?)


i looked into vtkDelaunay3D.cxx and could find no trace of multithreaded
code as well.


but it should be possible to run the delaunay algorithm with multiple
threads i guess.


a "google summer of code" task?



can someone confirm or otherwise shed some light in here please?

is it possible? does it scales? would it be worth the effort?



thanks,

kl
