NAME

       nose - test geomview's picking facility

DESCRIPTION

       Nose is a geomview module which tests the geomview picking facility.

       Nose has no panel of its own.  You invoke it by selecting the "Nose" line in the APPLICATIONS browser.  Once invoked, nose waits for you to
       click the right mouse button with the cursor over some object in a geomview camera window.  It then draws a little box on  the  spot  where
       you clicked.  If the picked spot is along an edge, it also draws a pair of boxes at the endpoints of the edge, and a line segment along the
       edge.  If the picked spot is on a vertex, the box is a different color.

       Nose is not necessarily intended to be a useful program.  It is just a simple example of how an external program can  find  out	about  and
       make use of geomview pick events.

NAME

       AnyToPL - convert an arbitrary geom to a polylist (OFF file format)

SYNOPSIS

       #include "geomutil.h"

       Geom *AnyToPL(Geom *, Transform);

DESCRIPTION

       AnyToPL()  takes  any  geom as an arguement.  It then returns a polylist object which is geometrically identical to the original geom.  The
       transform argument is the transform applied to the entire object; it should generally be set to TM_IDENTITY when AnyToPL() is first called.
       Geometric objects are handled in the following ways:

       Polylists:  A transformed copy of the original is returned.

       Bezier:	The object is rediced if necessary, then handled as a mesh object.

       Quad:  The object is directly transformed into a new polylist.

       Mesh:  The object is directly transformed into a new polylist, with extra polygons added to do the wrapping if necessary.

       Vect:  The object is converted into a polylist containing a 2-gon for every segment in the original vector object.  The colors of the faces
       are the same as the colors of the original object, but this generally is irrelevant since the faces are not visible.  Note that edge  visi-
       bility must be enabled for an object which has been converted from a vect to a polylist to be visible in geomview.

       List:  AnyToPL() is called recursively and the resultant polylists are combined using PLCombine(3).  Inst:  AnyToPL() is called recursively
       with a new transformation matrix.  The resultant polylists are combined using PLCombine(3).

       No effort is made to eliminate identical vertices.  However, no extraneous repeated vertexes should be  created.   The  resultant  polylist
       should have the same number of vertexes as the original object.

LINKING

       AnyToPL() is part of the geomutil library; see geomutil(3) for information on how to link your program with this library.
