Advanced Multi-Frame Rate Rendering Techniques

Multi-frame rate rendering is a parallel rendering technique that renders interactive parts of the scene on one graphics card while the rest of the scene is rendered asynchronously on a second graphics card. The resulting color and depth images of both render processes are composited and displayed. This paper presents advanced multi-frame rate rendering tech-niques, which remove limitations of the original approach and reduce artifacts. The interactive manipulation of light sources and their pa-rameters affects the entire scene. Our multi-GPU deferred shading splits the rendering task into a rasterization and lighting pass and distributes the passes to the appropriate graphics card to enable light manipulations at high frame rates independent of the geometry com-plexity of the scene. We also developed a parallel volume rendering technique, which allows the manipulation of objects inside a translu
