Hardware Ray Tracing using Fixed Point Arithmetic Johannes Hanika Ulm University Alexander Kellery Ulm University September 19, 2007 Abstract For realistic image synthesis and many other simulation applications, ray tracing is the only choice to achieve the desired realism and accuracy. Ray tracing has become such an important algorithm that an implemen-

In analogy to raster-ization hardware we therefore investigate the use of fixed point arithmetic for ray tracing. Our software implementation and comparisons provide strong evidence that an implementation of ray tracing in hardware using fixed point arithmetic is an efficient and robust choice. 1 Keyphrases

We will analyze these issues and the required ranges and present a realization of ray tracing in šxed point arithmetic that achieves the precision of a žoating point implementation. e hardware implementation is considerably more compact and simpler than a realization using žoating point or logarithmic arithmetic. 1.4 Ray ...

Ray tracing is an operation intensive program, which is definitely not good; 2. Using fixed-point numbers, when computers generally do not have floating-point units, we use fixed-point numbers instead of decimal operations. Multiplication and division is only a few times slower than integer operation, which is acceptable.
Reduced Precision Hardware for Ray Tracing

Fixed function traversal unit implements: 1. Two 1 bit precision traversal point updates 2. Two 5 bit precision robust Ray-AABB tests 3. Near child detection 4. Single bit traversal stack 5. … A fully pipelined traversal unit is roughly 6% the area of a single SIMD FPU in a current GPU.

As ray-tracing simulates light transport it is simple to get realistic images using this technique. This is why it is often used when realism is the top priority, e.g. in rendering movies. Rasterization on the other hand is easy to accelerate and the de facto standard for interactive visualisations and games. (This is of course a simplified view.)
