De engine wordt ontwikkeld als onderdeel van een groter project, het Intel Rendering Framework, dat zich richt op het ontwikkelen van softwarematige visualisatie voor wetenschappelijke berekeningen, SDVis (Software Defined Visualization), inclusief de ray tracing bibliotheek Embree, het fotorealistische rendering systeem GLuRay, de bibliotheek voor het verminderen van ruis in afbeeldingen oidn (Open Image Denoise) en het softwarematige rasterisatiesysteem OpenSWR. De code is geschreven in C++ en uitgebracht onder de Apache 2.0-licentie.    <\/p>\n<p>OSPRay is mainly aimed at use in interactive applications for rendering scenes on the fly. A path tracing method is used to simulate the behavior of light. Visualization is supported in both volume and on surfaces, with photorealistic global illumination considering the physical properties of materials, as well as advanced shading effects (shadows, transparency, and 'Ambient occlusion' shading).    <\/p>\n<p>OSPRay kan zonder afhankelijkheid van de GPU werken, wat het mogelijk maakt om de bibliotheek op een breed scala aan apparaten te gebruiken, van werkstations tot nodes in rekencentra. Voor een optimale prestatie wordt veel gebruik gemaakt van multithreading en vectorisatie op basis van SIMD-instructies, zoals Intel SSE4, AVX, AVX2 en AVX-512 (OSPRay vereist ten minste ondersteuning voor SSE4.1).     <\/p>\n<p>Rendering can be distributed across multiple nodes in a cluster (MPI is supported), allowing for the use of OSPRay to render images with very high resolution on video walls, where a single image is formed by a set of individual LCD panels. For example, the work of OSPRay has been demonstrated on the composite screen Stallion, composed of 80 30-inch monitors (with a total resolution of 40960\u00d78000 or 328 megapixels) serviced by a cluster of 40. <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/nl\/server\/\"   title=\"servers\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"1698\">servers<\/a> met 6-core CPU's gebaseerd op de Intel Sandy Bridge microarchitectuur.     <\/p>\n<p>Onder de toegevoegde wijzigingen:  <\/p>\n<ul>\n<li class=\"l\"> An experimental capability has been implemented to use Intel Xe GPUs (Intel Arc series Flex and Max) for hardware acceleration of ray tracing (in previous versions of OSPRay, ray tracing was performed only on the CPU). GPU support is achieved through the SYCL layer, which allows the creation of heterogeneous applications in C++ (DPC++ \u2014 Data Parallel C++). Not all rendering capabilities are yet available when using the new 'gpu' device; for example, cropping, blurring, and piecewise construction of smooth surfaces (Subdivision) are not supported yet.\n<li class=\"l\"> Er is impliciete indexering van de geometrie van polygonale mesh toegevoegd.\n<li class=\"l\"> Ondersteuning voor het overdragen van eigenaar van tijdelijke buffers is toegevoegd.\n<li class=\"l\"> De MPI-module is geoptimaliseerd, mogelijk gemaakt door de nieuwe ge\u00efntegreerde toolset voor prestatiemonitoring.\n<li class=\"l\"> De gradient fill in de SciVis-renderer is geoptimaliseerd.\n<li class=\"l\"> Er zijn wijzigingen aangebracht in de API die de compatibiliteit verstoren. Ondersteuning voor verouderde parameters en aanroepen is stopgezet.\n<li class=\"l\"> De vereisten voor de minimale versies van afhankelijkheden zijn verhoogd: Embree 4.3.0, Open VKL 2.0.0, Open Image Denoise 2.1.0, ISPC 1.21.1 en rkcommon v1.12.0.    <\/ul>\n<p>    <center><img decoding=\"async\" alt=\"Intel heeft de engine voor gedistribueerde ray tracing OSPRay 3.0 uitgebracht\"
