VG_ARC(3)		 BSD Library Functions Manual		     VG_ARC(3)

NAME
     VG_Arc -- agar-vg arc entity

SYNOPSIS
     #include <agar/core.h>
     #include <agar/gui.h>
     #include <agar/vg.h>

DESCRIPTION
     VG_Arc is a VG(3) node class which	describes an arc in terms of a center-
     point, radius and and two angles.

INTERFACE
     VG_Arc * VG_ArcNew(VG_Node	*parent, VG_Point *centerPoint,	float r, float
     a1, float a2)

     void VG_ArcCenter(VG_Arc *va, VG_Point *centerPoint)

     void VG_ArcRadius(VG_Arc *va, float r)

     void VG_ArcAngles(VG_Arc *va, float a1, float a2)

     The VG_ArcNew() function creates a	new arc	entity attached	to parent.
     centerPoint is a VG_Point(3) defining the center of the arc and r is the
     radius.  The starting and ending angles are specified by a1 and a2, in
     radians.

     The VG_ArcCenter()	routine	changes	the centerpoint	of an existing VG_Arc.
     VG_ArcRadius() changes the	radius.	 VG_ArcAngles()	changes	the angles.

SEE ALSO
     VG(3), VG_Circle(3), VG_Point(3)

HISTORY
     The VG_Arc	class first appeared in	Agar 1.3.3.
