A software development kit for achieving high performance ray tracing on the GPU.
The OptiX API is an application framework for achieving optimal ray tracing performance on the GPU. It 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.
From film and games to design and scientific visualization, OptiX has been successfully deployed in a broad range of commercial applications. These applications range from rendering software to scientific visualization (including Gordon Bell Award finalists), defense applications, audio synthesis, and computing lightmaps for games.
NVIDIA rendering partners can add AI-accelerated denoising to their renderers using the SDK.
Pixar Animation Studio's new material editing tool "Flow" enables their artists to interactively edit rich, complex shading networks. Flow provides live real-time feedback with full, multi-bounce progressive ray tracing using OptiX.
Visual Molecular Dynamics (VMD) is a molecular visualization program for displaying, animating, and analyzing large biomolecular systems using 3-D graphics and built-in scripting. VMD’s preferred rendering mode for both viewport and final render is OptiX, with full VCA support available. The OptiX path renders the highest visual quality and even has a frame rate five times higher than OpenGL on massive datasets.
NVIDIA Iray employs OptiX technology for optimal performance in both its path tracing and ray tracing render modes. Iray is a state of the art, yet easy to use, photorealistic rendering solution provided as an SDK for seamless integration into custom tools and within industry-leading products from the likes of Dassault Systemes and Siemens PLM.
SOLIDWORKS® Visualization products (formerly known as Bunkspeed) provide a suite of standalone software tools that combine industry-leading rendering capabilities with design-oriented features and workflows that enable easy and fast creation of visual content for designers, engineers, marketing, and other content creators. Import SOLIDWORKS, Autodesk Alias®, Rhino®, SketchUp® and many other CAD formats to create compelling scenes and ultimately the most realistic content possible.
OPTIS, the virtual prototyping company, brings life and emotion to all industrial projects. Its world-leading solutions pave the way for a revolutionary design process: towards zero physical prototypes. Since 1989, OPTIS offers its know-how in light and human vision simulation into leading CAD/CAM software and dedicated immersive virtual solutions. This synergy creates true-to-life virtual mockups which are used as real decision-making tools. Today, more than 2,500 clients in over 50 countries already trust OPTIS and innovate day after day with its solutions to ensure the look and safety of their designs, reduce their ecological footprint and bring their future products faster on the market.
“We use powerful NVIDIA GPU technologies, like the new Quadro GV100 to accelerate our simulation applications and algorithms, and NVIDIA OptiX for fast AI-based rendering. Looking ahead, we’re excited about the potential NVIDIA RTX ray-tracing technology holds to deliver more lifelike images faster than ever,” said Jacques Delacour, CEO and founder of OPTIS.

We’re finding the NVIDIA denoising results to be very impressive on interactive scenes, giving artists a much quicker estimate of what their final result will look like. We believe this will speed the creative process while using our upcoming V-Ray GPU.Vlado Koylazov, founder, Chaos Group
Founded by animation industry veterans, Isotropix™ is a start-up specialized in developing high-end professional graphics software and aims at providing CG artists game-changing innovations.
Thanks to its AI-driven denoising capability, OptiX 5.0 accelerates the Clarisse path tracer up to eight times! Combined with TITAN V, it will be a game changer for artists as they can make instant creative decisions on images that are very close to final renders — all from their PC.Sam Assadian, CEO and co-founder, Isotropix

It was staggering to witness OptiX 5.0’s ability to create clean images that are genuinely representative of the final frame. As Clarisse continues to refine the render, the denoiser converges on the final clean result in a smooth, deterministic way, meaning that artists are able to make detailed artistic lighting decisions considerably faster than they could before.Graham Jack, chief technology officer, Double Negative
Redshift Rendering Technologies Inc was founded in early 2012 in Newport Beach, California with the goal of developing a production-quality, GPU-accelerated renderer with support for the biased global illumination techniques that until now have remained squarely in the CPU-only domain.

This is a set of advanced samples for the NVIDIA OptiX Ray Tracing Engine. They assume some previous experience with OptiX and physically based rendering, unlike the basic tutorial-style samples in the SDK directory of the OptiX 4.0 distribution. They also use some different libraries than the SDK samples; GLFW and imgui in place of GLUT, for example. This means you cannot generally copy one of the advanced samples directly into the SDK, and vice versa.
