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.
