May 1, 2021Getting started with NVIDIA OptiXRay tracing Photorealism is a technique aiming at obtaining artificial images indistinguishable from natural ones. Photorealistic images require the full simulation of light propagation, reflection and refraction from a light source, passing through the surfaces involved in the illumination until the light reaches the human eye. All the electromagnetic properties…Cuda4 min read
