Can anyone tell me about, or point me to descriptions of, the ?five?
different acceleration structures (BSP, CellSkipper, RecursiveGrid,
KDTree, RecursiveGrid) in Manta?

vtkManta uses DynBVH, and it appears to be the fastest so far, but it
doesn't seem to scale all that well when the number of triangles
increases. I am wondering if one of the others (with well chosen
settings) would be a better choice.

So far, vtkManta isn't changing the contents of the DynBVH, so the
Dynamic nature of it isn't that important (but quick build times are
important).

We do want to be able to have (groups of) triangles, cylinders and
spheres in the acceleration structure so a non-homogenous acceleration
structure is preferable.

thanks for any pointers,
