Detailed Description

Builds the space leaping data structure.

This is an optimized multi-threaded imaging filter that builds the space leaping datastructure, used by vtkFixedPointVolumeRayCastMapper. Empty space leaping is used to skip large empty regions in the scalar opacity and/or the gradient opacity transfer functions. Depending on the various options set by vtkFixedPointVolumeRayCastMapper, the class will internally invoke one of the many optimized routines to compute the min/max/gradient-max values within a fixed block size, trying to compute everything in a single multi-threaded pass through the data

The block size may be changed at compile time. Its ifdef'ed to 4 in the CXX file.
