NVIDIA OptiX is described as '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' and is an app in the photos & graphics category. There are six alternatives to NVIDIA OptiX for Mac, Windows, Linux, Blender and Self-Hosted. The best NVIDIA OptiX alternative is Cycles Renderer, which is both free and Open Source. Other great apps like NVIDIA OptiX are Mitsuba, Radeon ProRender, YafaRay and OSPRay.
Cycles is Blender’s ray-trace based production render engine and in development since 2011. It was originally developed by Brecht van Lommel, and is maintained by an active team of developers today. Since its release as Apache 2.
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.
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.
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...
