Formulas
Units: Inches (for millimeters multiply final number by 25.4)
Definitions:
H= Horizontal Screen Width (4:3)
V= Vertical Screen Height (4:3)
B= Vertical distance between lens center and screen center
C= Throw distance
D= Vertical distance between lens center and screen top (screen bottom for desktop application)
α= Throw Angle
Projection Formulas: Screen Formulas (4:3):
B= 0.3193H H= Screen Diagonal x 4/5
C(wide) = 1.8588H – 3.171 V= Screen Diagonal x 3/5
C(tele) = 2.2299H – 2.710 Screen Diagonal = H x 5/4
D= 0.0557H
