NAME    [Toc]    [Back]

     callobj - draws an	instance of an object

C SPECIFICATION    [Toc]    [Back]

     void callobj(obj)
     Object obj;

PARAMETERS    [Toc]    [Back]

     obj   expects the object identifier of the	object that you	want to	draw.

DESCRIPTION    [Toc]    [Back]

     callobj draws an instance of a previously defined object. If callobj
     specifies an undefined object, the	system ignores the routine.

     Global state attributes are not saved before a call to callobj. Thus, if
     you change	a variable within an object, such as color, the	change can
     affect the	caller as well.	 Use pushattributes and	popattributes to
     preserve global state attributes across callobj calls.

     Likewise, the object may execute transformations that change the matrix
     stack, so you may want to use pushmatrix and popmatrix to restore the
     state of the matrix stack.
