DESCRIPTION
vtkVoxelModeller is a filter that converts an arbitrary data set to a structured point (i.e., voxel) representation. It is very similar to vtkImplicitModeller, except that it doesn't record distance; instead it records occupancy. As such, it stores its results in the more compact form of 0/1 bits.

SUMMARY
void SetMaximumDistance(float)
Specify distance away from surface of input geometry to sample. Smaller values make large increases in performance.
vtkVoxelModeller()
Construct an instance of vtkVoxelModeller with its sample dimensions set to (50,50,50), and so that the model bounds are automatically computed from its input. The maximum distance is set to examine the whole grid. This could be made much faster, and probably will be in the future.
void SetModelBounds(float *bounds)
Specify the position in space to perform the voxelization.
float ComputeModelBounds(float origin[3], float spacing[3]) Compute the ModelBounds based on the input geometry.
void SetSampleDimensions(int i, int j, int k)
Set the i-j-k dimensions on which to sample the distance function.
