SUMMARY
	Nname	geom2iv

	Type	data output

	Inputs	geometry (required: in)

	Outputs	none

	Parameters	Name	Type
			ivfile	browser

DESCRIPTION

  This module interprets AVS geometry data into Inventor format(V2.0 ascii) and
  writes it out to a new file.

  Supported geometry types :
     + GEOM_MESH
     + GEOM_POLYHEDRON
     + GEOM_POLYTRI - includes polyline and disjoint line.
		When a GEOM_POLYTRI object includes both polygons and lines,
		geom2iv ignore the lines and won't outputs them.
     + GEOM_SPHERE
     + GEOM_LABEL - except title labels.

  geom2iv treats "normals" and "colors" of above geometry types, when added.
  But, not supports "texture" data.

INPUTS

    in (required: geometry)
	Any AVS geometry.

PARAMETERS

    ivfile
	A browser that allows you to specify the name of the Inventor
	file to be created.
	Note: after the file is written, the filename is *NOT* reset to NULL.

EXAMPLE

  1) This example converts a geometry, which "read geom" module reads,
     into an Inventor file:

		    read geom
		        |
		        +----------------+
		        |                |
		geometry viewer	      geom2iv

  2) This example converts an arbitrary slice into an Inventor file.

		generate colormap         read volume
		        |                      |
		        +-------+      +-------+
	                        |      |
		           arbitrary slicer
		                       |
		        +--------------+
		        |              |
		geometry viewer	    geom2iv
