DESCRIPTION
VG_Arc is a
VG(3) node class which describes an arc in terms of a centerpoint, 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.
