The increase in graphics card performance and processor core count has allowed significant performance acceleration for ray tracing applications. Future graphics architectures are expected to continue increasing the number of processor cores, further improving performance by exploiting data parallelism. However, current ray tracing implementations are based on recursive searches which involve multiple memory reads. Consequently, software implementations are used without any dedicated hardware acceleration. In this paper, the authors introduce a ray tracing method designed around hierarchical space subdivision schemes that reduces memory operations.
