VG_ARC(3)		     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 ra-
     dians.

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