Ergonomics is an important aspect engineering of manufacturing systems andmaintenance procedures of new products for both physical and virtual envronments . A specific case is the prediction of operator or technician visibility under real world lighting conditions. For example, when simulating how efficiently a worker will be able to operate a planned system, it is necessary to evaluate early on how this would be affected by a given illumination situation. The ability to digitally design for manufacturability or serviceability, while taking into account human factors, directly influences the potential profitability of new products.  In this session, we will talk about how NVIDIA's OptiX and RTX ray tracing technologies can be leveraged to simulate the propagation of light in environments with complex geometric topology on GPUs.
