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 cen-
       terpoint, 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.

Agar 1.7		       December	21, 2022		     VG_ARC(3)
