DESCRIPTION:

     The ucd to wave module writes an ucd structure to disk, in wavefront format, format
     which is supported by Data Visualizer.

     Ucd to wave works only with node data, therefore if you have cell data , you have
     to transform the cell data to node data using the cell to node module.

     Because Data Visulizer doesn't use mid-edge nodes, at this version,
     the ucd to wave module, generally doesn't use the mid-edge nodes.
     One exception has been made: if the ucd cell is triangle with all mid-edge nodes
     present, ucd to wave module will split the triangle in 4 triangles.
     The user can change the module to support another ucd type which use mid-edge nodes.

     The wavefront file, that will be written to disk is an ASCII file.


INPUTS 
    ucd structure
       The input can be any UCD structure with node data

PARAMETERS
 
   Filename wave
       A file browser that allows you to specify the name of the wave file
       to be created

EXAMPLES

  The following structures reads in a UCD structure, and writes the wave file to disk:
  
1.       READ  UCD                  (node data)
	     |
	     |
	     |
	UCD TO WAVE


2.	  READ  UCD                 (cell data)
	     |
	     |
	 CELL TO NODE
	     |
	     |
