With the shift from highly clocked, single thread processors to chips that have dozens or even hundreds of smaller processors, we are witnessing a fundamental change in the computing hardware we use. This paper describes an approach to use modern many-core-hardware to apply real time ray tracing to Virtual Reality environments. We show that current hardware can speed up real time ray tracing to interactive frame rates that make ray tracing interesting for the integration into existing industrial Virtual Reality systems.
