DESCRIPTIONThis module reads an AVS(tm) ucd file and outputs a pyramid. The ucd structure can contain node-based data and cell-based data; this gets put into the base lattice and the top lattice of the pyramid. The lattices are also output separately.
Port: Input File
Constraints: 1..3-D compression
Constraints: n-compression type
Base lattice of the pyramid, containing the data and coordinates for all the nodes (vertices) in the ucd structure.
Lattice from the top layer of the pyramid, containing the data for all the cells in the ucd structure. The lattice also contains coordinates for each data value. These cannot be obtained from the ucd structure (which does not include this information); instead, the coordinates to be associated with a cell data value are calculated by averaging over the coordinates of the vertices at the corners of the cell.
