Throw Distance Inputs

Throw distance = image width × throw ratio. Width is per overall image, not per projector.

Image Size Inputs

Image width = throw distance ÷ throw ratio. Optional overlap only affects per-projector effective coverage.

Edge Blend Inputs

This assumes overlap is a percentage of each projector image width. Overall width = (N × image width) − ((N−1) × overlap width).
