We present a real-time reverse radiosity method for compensating indirect scattering effects that occur with immersive and semi-immersive projection displays. It computes a numerical solution directly on the GPU and is implemented with pixel shading and multi-pass rendering which together realizes a Jacobi solver for sparse matrix linear equation systems. Our method is validated and evaluated based on a stereoscopic two-sided wall display. The images appear more brilliant and uniform when compensating the scattering contribution.
