A GPU interval library based on Boost . Interval ∗

Interval arithmetic is widely used in numerical algorithms requiring reliability. Ray tracing of implicit surface is one of these applications that use interval arithmetic to increase the quality of a produced image. However these applications are computationally demanding. One solution is to use graphics processing unit (GPU) in order to take advantage of its computational power. We describe in this paper a GPU implementation of interval operators based on the Boost library. We tested these operators on a ray tracing algorithms and observe several order of execution speed improvements over the CPU version with the same image quality.
