3D Data

Visualising clumps in 3D is much harder. Options include the following.

  1. Examining specified 2D slices from the 3D data. For instance to display the intersection of the tenth pixel plane with clump number 12, do:

         % display "clumps.more.cupid.clumps(12)(,,10)" mode=perc badcol=red accept
    

  2. Use the 3D facilities of GAIA , accessed through the Open cube entry in the File menu.

  3. Use a complete 3D visualisation such as OpenDX (see http://www.opendx.org/). The facilities of the Starlink DX extension package (known as ``SX'' SX ) may be useful as it provides a means of converting NDF data files to the DX native format, and also provides some demonstration DX ``networks'' that can be used to do simple visualisations of a 3D data cube.
