    Image Based Rendering from Perspective and Orthographic Images for Autostereoscopic Multi-View Displays
    (The Eurographics Association, 2013) Jung, Daniel; Koch, Reinhard; Michael Bronstein and Jean Favre and Kai Hormann
    Current autostereoscopic (AS) multi-view displays for video that are targeted at the market allow typically up to 60 frames per second and offer between 20 and 60 different views per pixel. Future full parallax AS displays may well require thousands of views simultaneously. With the large number of different views video displays consume a huge amount of data, either transferred to the display or to be computed on demand from a 3D scene representation. In the following a novel depth-image based rendering interpolation algorithm targeted at multi-view video displays is introduced that combines the results of an interpolation on orthographic and perspective images. The same idea is further utilised to implement an efficient computer graphic rendering algorithm for full parallax AS displays.

    Towards Multi-Kernel Ray Tracing for GPUs
    (The Eurographics Association, 2013) Schiffer, Thomas; Fellner, Dieter W.; Michael Bronstein and Jean Favre and Kai Hormann
    Ray tracing is a widely used algorithm to compute images with high visual quality. Mapping ray tracing computations to massively parallel hardware architectures in an efficient manner is a difficult task. Based on an analysis of current ray tracing algorithms on GPUs, a new ray traversal scheme called batch tracing is proposed. It decomposes the task into multiple kernels, each of which is designed for efficient execution. Our algorithm achieves comparable performance to state-of-the-art approaches and represents a promising avenue for future research.
