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. Â 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. A special focus will be on the OptiX AI denoiser, which masks Monte-Carlo noise that is stemming from the underlying numerical integration methods. We will show how this has been integrated into ESI's Helios visualization framework, before we demonstrate the system through practical examples
Illuminating Engineering Society (IES) light profiles and X-Rite's Appearance Exchange Format (AxF) are popular file formats for the distribution of measured light and surface appearance data. In this talk, we will demonstrate how IES and AxF data can be used as building blocks within NVIDIA's Material and Definition Language (MDL) to create and design complex physically based materials focusing on measured content. We will demonstrate a prototypical implementation which has been integrated in ESI's IC.IDO decision making platform.
