Image Data
Points are arranged on a regular, rectangular lattice parallel to the global coordinate system.
Rectilinear Grid
This is a slight extension of Image Data. The points are still aligned along the coordinate axis, but the spacing between points may vary.
Structured Grid
Regular topology and irregular geometry. That is, every point has a left, right, up, down, front, back neighbor. The points, however, do not lie on a grid!
This data structure is common in finite difference analysis.
Polygonal Data (PolyData)
Unstructured topology and geometry. Supports 0,1, and 2D cells.
Unstructured Grid
This is the most general form of data storage. Both topology and geometry are completely unstructured. Supports 0,1,2, and 3D cells.
