In an attempt to quantify the relative merits of various platforms for rendering with Radiance, two scenes were designed each with quite different attributes. The first (bench1.tar.gz) has a very small memory footprint, the second (bench2.tar.gz) is much more demanding both in terms of memory and runtime.
ResultsThe statistics that follow are the time it took the respective machines to render the scenes in seconds (lower the better). Radiance reports user and system times, these were checked against the results from the UNIX "time" command. In general, special compiles were not created.
