Intel has published the scalable 3D rendering engine OSPRay 3.0, designed for realistic high-quality visualization using ray tracing. The engine is developed as part of the larger Intel Rendering Framework project, aimed at creating software visualization tools for scientific computations (SDVis \u2014 Software Defined Visualization), including the Embree ray tracing library, the GLuRay photorealistic rendering system, the Open Image Denoise (oidn) library for image noise reduction, and the OpenSWR software rasterization system. The code is written in C++ and released under the Apache 2.0 license. <\/p>\n

OSPRay is primarily aimed at use in interactive applications for real-time scene rendering. The method of path tracing is used to simulate the behavior of light. It supports volume and planar visualization, photorealistic global illumination considering the physical properties of materials, and advanced shading effects (shadows, transparency, and ambient occlusion). <\/p>\n

OSPRay can operate without being tied to a GPU, allowing the library to be used on a wide range of devices, from workstations to nodes in computing clusters. To ensure adequate performance, it actively utilizes multithreading and vectorization based on SIMD instructions, such as Intel SSE4, AVX, AVX2, and AVX-512 (OSPRay requires at least SSE4.1 support). <\/p>\n

Rendering can be distributed across multiple cluster nodes (MPI supported), allowing OSPRay to be used for rendering high-resolution images on video walls, where a single image is formed by a set of individual LCD panels. For example, OSPRay's capabilities were demonstrated on the Stallion composite screen, composed of 80 30-inch monitors (with a total resolution of 40960\u00d78000 or 328 megapixels) and supported by a cluster of 40. servers<\/a> with 6-core CPUs based on the Intel Sandy Bridge microarchitecture. <\/p>\n
