Detailed Description

Singleton class for topologically regular data.

vtkStructuredData is a singleton class that provides an interface for topologically regular data. Regular data is data that can be accessed in rectangular fashion using an i-j-k index. A finite difference grid, a volume, or a pixmap are all considered regular.
