“…For every pixel this recursive approach automatically combines all visible shading effect correctly without involving the application or the need for separate rendering passes. Even memory management of the graphics card's memory is handled automatically by the ray tracer [SLS03].…”

Recently, realtime ray tracing has been developed to the point where it is becoming a possible alternative to the current rasterization approach for interactive 3D graphics. With the availability of a first prototype graphics board purely based on ray tracing, we have all the ingredients for a new generation of 3D graphics technology that could have significant consequences for computer gaming. However, hardly any research has been looking at how games could benefit from ray tracing.In this paper we describe our experience with two games: The adaption of a well known ego-shooter to a ray tracing engine and the development of a new game especially designed to exploit the features of ray tracing. We discuss how existing features of games can be implemented in a ray tracing context and what new effects and improvements are enabled by using ray tracing. Both projects show how ray tracing allows for highly realistic images while it greatly simplifies content creation.

“…Hardware support for multi‐GPU systems has been developed by leading hardware vendors like NVIDIA and AMD [NVI05, Per05], as well as by academics [MBOD06]. Much research has also been done in virtualizing memory systems for both raster based and ray traced graphics systems [Hal99, SLS03, DPH*03].…”

In this work, we demonstrate a system that allows texture memory on multiple graphics processing unit (GPUs) to be virtualized in a manner that is both scalable and transparent to the programmer. Our system is built using a directory-based shared-memory abstraction to allow texture memory to be distributed while staying consistent. We use texture pages as our basic memory block and discuss the data structures, threading model, and consistency mechanisms necessary to implement a paging system in a multi-GPU environment. The system is demand-driven, and pages will only be loaded into the texture memory of a GPU that makes a request. The main contribution of this work is the identification of the mechanisms required to implement our abstraction, as well as the discussion of its limitations in order to make it more efficient.

We present a novel FPGA-accelerated architecture for fast collision detection among rigid bodies. This paper describes the design of the hardware architecture for several primitive intersection testing components implemented on a multi-FPGA Xilinx Virtex-II prototyping system. We focus on the acceleration of ray-triangle intersection operation which is the one of the most important operations in various applications such as collision detection and ray tracing.Our implementation result is a hardware-accelerated ray-triangle intersection engine that is capable of out-performing a 2.8 GHz Xeon processor, running a well-known high performance software ray-triangle intersection algorithm, by up to a factor of seventy. In addition, we demonstrate that the proposed approach could prove to be faster than current GPU-based algorithms as well as CPU based algorithms for ray-triangle intersection.
