Compare laser scan angle against throw distance when placing projectors and predicting coverage.
Compare laser scan angle against throw distance for projector placement and coverage planning.
Solve either coverage size from angle and distance, or required angle from target size.
Formulas: W = 2·L·tan(θ/2). Inverse: θ = 2·atan(W/(2·L)). Use full angles.
Rectangular coverage at the throw distance. Angles are full-field.

| × 1 | 10.72 m | 7.05 m |
| × 1.5 | 16.08 m | 10.58 m |
| × 2 | 21.44 m | 14.11 m |
| × 3 | 32.15 m | 21.16 m |
