Abstract
A primary image is transformed into secondary images for projection, via first and second frame buffers and view projection matrixes. To do so, a first image is loaded into the first frame buffer. A calibration data set, including the view projection matrixes, is loaded into an application. The matrixes are operable to divide and transform a primary image into secondary images that can be projected in an overlapping manner onto a projection screen, providing a corrected reconstruction of the primary image. The first image is rendered from the first frame buffer into the second images, by using the application to apply the calibration data set. The second images are loaded into a second frame buffer, which can be coupled to the video projectors.
