Detailed Description

Generates a structured extent from unstructured.

vtkExtentTranslator generates a structured extent from an unstructured extent. It uses a recursive scheme that splits the largest axis. A hard coded extent can be used for a starting point.

void vtkExtentTranslator::SetSplitModeToBlock ( )
inline

How should the streamer break up extents. Block mode tries to break an extent up into cube blocks. It always chooses the largest axis to split. Slab mode first breaks up the Z axis. If it gets to one slice, then it starts breaking up other axes.

void vtkExtentTranslator::SetSplitPath ( int  len,
int splitpath 
)

By default the translator creates N structured subextents by repeatedly splitting the largest current dimension until there are N pieces. If you do not want it always split the largest dimension, for instance when the shortest dimension is the slowest changing and thus least coherent in memory, use this to tell the translator which dimensions to split.
