From the developer:
BlendCalc is a wide-screen projection calculator. Use it to determine how many projectors are needed to create a wide-screen image. Specify the screen size, projector type and throw distance or lens ratio and it calculates projector positions, pixel space and overlap. If a perfect fit is not possible then a best-fit solution is provided. Explore any given solution by changing the number of specified projectors at the touch of a button.
