Projector edge blends, costed.
A projector edge-blend calculator that runs entirely in your browser. Flat or cylindrical canvas, any array, and the solver closes the array on the screen exactly. Then it tells you the system resolution, how much doubled and quad-covered overlap you're paying for more than once and the lens each position needs, and hands you a PDF report and a Resolume Arena advanced-output file.
Blend Calc runs in the browser and needs JavaScript.
