AbstractRay tracing is a simple but powerful image synthesis technique known to produce realistic images but at a high computational cost and therefore with long computing execution times. Several acceleration techniques have already been devised to minimize this drawback. This work presents two acceleration techniques which take advantage over the inherent parallelism of ray tracing. The first technique uses a MIMD machine and the second one uses an heterogeneous parallel system consisting of a MIMD and a SIMD machine. The aim of this work is to prove that heterogeneity makes the second more efficient than the first. The results show that the heterogeneous technique produces good savings in computing execution times in comparison to the homogeneous one.
