Generalization of Single-Center Projections Using Projection Tile Screens

This work presents an image-based approach to efficiently generate multiple non-planar projections of arbitrary 3D scenes in real-time. The creation of projections such as panorama or fisheye views has manifold applications, e.g., in geovirtual environments and in augmented reality. Our rendering technique is based on dynamically created cube map textures in combination with shader programs that calculate the specific projections. Based on this principle, we present an approach to customize and combine different planar as well as non-planar projections. Our technique can be applied within a single rendering pass, is easy to implement, and exploits the capability of modern programmable graphics hardware completely.
