In others, the visual cues obtained by the physically based rendering process, including shadows, ambient occlusion, or even depth-of-field effects, can help to better understand the spatial relationship of the objects in the scene. Far beyond making pretty pictures for publication and outreach, the resulting photo-realism can in some cases be used for direct comparisons between simulation output and observations. ParaView accelerated by the latest-generation GPUs, especially with the RT Cores devoted to ray tracing found on NVIDIA’s Turing GPUs, brings a wide range of benefits to scientific visualization.
