NAME
     transformer - Tool	for manipulating geomview transforms.

SYNOPSIS
     transformer

DESCRIPTION
     Transformer is a tool to manipulate the wrap  transforms  of
     geomview objects.	When transformer is started, it	will read
     in	the wrap transform of the target object.   The	transform
     will be displayed at the top of the panel.

     The displayed transform may at any	time be	set to	the  wrap
     transform	of  the	 geomview  target  object by pressing the
     "Read" button at the bottom of the	 panel.	  Note	that  the
     transform	does not automatically update whenever the target
     object moves.  The	transform may also be set to the identity
     by	 pressing  the	"Identity"  button  at	the bottom of the
     panel.

     The transform may also be applied	to  the	 geomview  target
     object by pressing	the "Apply" or "Set" button.  The "Apply"
     button will cause the current wrap	transform of the  current
     target   object   to  be  postmultiplied  by  the	displayed
     transform.	 The "Set" button will cause the  wrap	transform
     of	 the  target  to be replaced by	the transform.	Note that
     the transform of the geomview target is not updated automat-
     ically when the transform displayed in the	panel changes.

     The displayed transform may be modified directly by changing
     the  numbers in the matrix.  In addition, a rotation, trans-
     lation, or	scale may be applied to	the  object.   To  rotate
     the object, enter the appropriate number of degrees or radi-
     ans in the	input field next to  the  "Degrees"  buttons  and
     press  the	 "Rotate"  button.   The displayed transform will
     then be postmultiplied by a rotation matrix of the	requested
     amount  about the specified axis.	In a similar fashion, the
     translate and scale sections of the panel	may  be	 used  to
     update the	transform.

     All operations are	Euclidean.

     The following keyboard shortcuts apply:
	  R	    Rotate
	  T	    Translate
	  S	    Scale
	  a or Space	 Apply
	  Return	 Set
	  r	    Read
	  i	    Identity
	  q	    Quit

BUGS
     The transform is read from	the current target when	the  pro-
     gram begins or the	read button is pressed.	 The transform of
     the current target	is modified by or set  to  the	displayed
     transform	when  the  "Apply"  or	"Set"  button is pressed.
     There is no check that the	user has not changed the geomview
     target  between  these two	operations.  Although the results
     of	such an	 operation  will  be  correct  according  to  the
     specifications  in	 this  man page, the results may be unex-
     pected.
