FPGA-based image combiner for parallel rendering

  • Rendering of virtual scenes is an application that still demands higher computing power for more complex and more realistic scenes. In addition to existing parallel processing inside a graphics processing unit, this paper investigates a further level of parallelization. A combiner based on an FPGA (field programmable gate array) allows to merge the graphics output of several independent computers. The image combiner supports different load distribution techniques, namely sort-first and sort-last rendering. A system prototype based on a commercial evaluation system proved the viability of the approach. A compact and cost-efficient dedicated implementation has been designed and is used as a platform to investigate different approaches for parallel rendering.
