Table 4. AP data used for input into PP computation. Here, there is a combination of 3D object points (AP, LAT, VERT) and 2D points on the display plane (U, V).

AP = Antero-Posterior; LAT = Lateral; VERT = Vertical; U = Horizontal Axis of Display Plane; V = Vertical Axis of Display Plane; PP = Perspective Projection; RPPT = Right Posterior Pin Tip; RPSS = Right Posterior Sphere Superior; RPSI = Right Posterior Sphere Inferior; RFPT = Right Frontal Pin Tip; RFSS = Right Frontal Sphere Superior; LPPT = Left Posterior Pin Tip; LPSS = Left Posterior Sphere Superior; LPSI = Left Posterior Sphere Inferior; LFSS = Left Frontal Sphere Superior; LFPT = Left Frontal Pin Tip; RFPB = Right Frontal Pin Base.
