OSPRay is described as 'Intel OSPRay is an open source, scalable, and portable ray tracing engine for high-performance, high-fidelity visualization on Intel Architecture CPUs. The purpose of OSPRay is to provide an open, powerful, and easy-to-use rendering library that allows one to easily build' and is an app in the development category. There are four alternatives to OSPRay for Mac, Windows, Linux, Self-Hosted and Blender. The best OSPRay alternative is Mitsuba, which is both free and Open Source. Other great apps like OSPRay are Radeon ProRender, YafaRay and NVIDIA OptiX.
Mitsuba is a research-oriented rendering system for forward and inverse light transport simulation. It consists of a core library and a set of plugins that implement functionality ranging from materials and light sources to complete rendering algorithms.
Mitsuba is the most popular Windows, Mac & Linux alternative to OSPRay.
Mitsuba is the most popular Open Source & free alternative to OSPRay.
AMD Radeon™ ProRender is a powerful physically-based path traced rendering engine that enables creative professionals to produce stunningly photorealistic images.
YafaRay is a free open-source montecarlo raytracing engine released under the LGPL 2.1 license. Raytracing is a rendering technique for generating realistic images by tracing the path of light through a 3D scene.
OptiX provides a simple, recursive, and flexible pipeline for accelerating ray tracing algorithms. Bring the power of NVIDIA GPUs to your ray tracing applications with programmable intersection, ray generation, and shading.
NVIDIA OptiX is the most popular Self-Hosted alternative to OSPRay.
