I know about the Bischoff approach, thanks anyway for the reference. 
It's different from the one by Han in that Bischoff introduces cuts in 
the voxel grid to isolate non-simple voxels, whereas Han have a simple 
test and a slightly adapted propagation step to prevent the front from 
traversing non-simple voxels.  It *looks* like Han's approach might be a 
tad simpler to implement...  we'll see.

Thanks,
Charl
