Abstract
One of the problems appearing in the virtual reality (VR) application is the image distortion and blending correction for curved screens with single or multiple projectors. There are ways to solve this problem via a special circuit implementation within the image projectors or via special image correction PC based boxes. In this study we proposed own algorithm for the image correction based on the back ray tracing approach. The algorithm is using reverse ray tracing and it was tested on the Cybersphere(1) setup. We propose the software implementation of the algorithm which allows using it for any programs not limited by a certain technology such as OpenGL for instance as in other image correction algorithms. The algorithm can be used for distributed image rendering and projection such as Chromium based sets.
