Due to the advent of ray tracing at interactive speeds and because there is an absence of a way to
measure and compare performance and quality of ray traced scenes that are animated, we present an
organized way to do this objectively and accurately in this proposal for BART: A Benchmark for Animated
Ray Tracing. This is a suite of test scenes, placed in the public domain, designed to stress ray tracing
algorithms, where both the camera and objects are animated parametrically. Equally important, BART is
also a set of rules on how to measure performance of the rendering. We also propose how to measure and
compare the error in the rendered images when approximating algorithms are used.
1 Introduction
In order to measure performance, benchmarks are needed, as they allow people to compare performance in
a more accurate and objective way. A benchmark is often a suite of test cases or executables together with a
specified procedure of how to report performance with that benchmark. There is a need for benchmarks in
