Edge blending is a technique that creates a seamless image across multiple projectors. The Edge Blending Calculator simplifies this process by providing a user-friendly interface to calculate necessary settings and parameters for edge blending, making it easier to create high-quality projections. Using the calculator, users input factors such as projector model, screen resolution, and placement to generate a custom solution. The tool also provides a simulated brightness result of the proposed solution for adjusting settings as needed. 

The renewed Edge Blending Calculator now comes in three types: one for creating a seamless image on a single large display, and the others for immersive displays with projection images on three surfaces (wall, floor, or ceiling). With this update, the calculator can be used for a wider range of projection setups and configurations.
