Abstract:
PBR materials have widely been adopted in real-time rendering engines because of their user-friendliness and high quality. But adoption has been weaker for ray tracing engines because PBR materials do not model effects indispensable for high-quality rendering. Businesses need consistent rendering between real-time and ray tracing engines, especially with the rise of ray tracing in real-time engines via NVIDIA RTX. We'll discuss an extended PBR material that expands the industry-standard PBR GGX. Our talk will cover details of the new material and demonstrate results from Dassault Systemes' OpenGL, WebGL and CUDA-based ray tracing engines. We'll also highlight its use in Allegorithmic Substance designer, XRite AxF, NVIDIA MDL distiller, and Dassault Systemes' software such as 3DEXPERIENCE Platform, SOLIDWORKS Visualize, and 3DEXCITE DELTAGEN.

Abstract:

X-Rite specializes in the construction of devices that acquire highly accurate color data. As part of our advanced development, we have engineered a process for generation of high dynamic range (HDR) spectral images from digital CCD cameras using highly characterized LED illumination sources. Our instrumentation involves multiple cameras and illumination sources arranged to produce a gonio-spectrophotometric set of images. Within this process, standard image processing techniques exacted a high computational cost and initially prevented this process from being attractive and useful. CUDA enabled us to achieve a roughly 140x computational improvement over the original implementation, both by parallelizing the computations via the GPU and by encouraging specific algorithm optimizations.
