Overview / Usage

This demo shows how the Intel® OSPRay plugin for USD Hydra can be used to explore and interact with professional DCC content based on Pixar’s open USD format. Using USD’s Hydra Plugin interface, the OSPRay plugin for USD Hydra seamlessly integrates the rendering capabilities of Intel® OSPRay, providing the user the experience and the benefits of multiple components of the Intel® oneAPI Rendering Toolkit such as: Intel® Embree, Intel® Open Image Denoise and, in the future, the Intel® Open Volume Kernel Library. This demo presents multiple use cases such as fast preview rendering for compositing and animation, as well as, high quality physically based rendering for lighting and final rendering. To show the scalability of the Intel oneAPI RenderKit we demonstrate the OSPRay for Hydra Plugin on different hardware configurations such as a high-fidelity 10 node compute cluster to a standard mid-range workstation (Intel® i9-7900X).

Methodology / Approach

Intel® OSPray for Hydra makes heavy use of three Intel® oneAPI Rendering Toolkit components:

• Intel® OSPRay: Providing the renderer itself, and supporting different rendering modes (preview or physical-based
• Intel® Embree: A high-performance CPU-based ray tracing kernel library
• Intel® Open Image Denoise: An AI-based denoising library for Monte-Carlo rendering, which enables us to produce high-quality images from smaller sample sets.
