NVIDIA RTX platform includes a ray tracing technology that brings real-time, cinematic-quality rendering to content creators and game developers.
The OptiX API is an application framework that leverages RTX Technology to achieve optimal ray tracing performance on the GPU.
It provides a simple, recursive, and flexible pipeline for accelerating ray tracing algorithms. Additionally the post processing API includes an AI-accelerated denoiser , which also leverages RTX Technology.
The post processing API can be used independently from the ray tracing portion of the pipeline. DXR fully integrates ray tracing into DirectX, allowing developers to integrate ray tracing with traditional rasterization and compute techniques.
NVIDIA partnered closely with Microsoft to enable full RTX support for DXR applications. NVIDIA VKRay is a set of extensions that bring ray tracing functionality to the Vulkan open, royalty-free standard for GPU acceleration.
Application developers can confidently build Vulkan applications that take advantage of ray tracing knowing that NVIDIA drivers will support the new extension.

Using a computer for ray tracing to generate shaded pictures originated with Goldstein and Nagel of MAGI Mathematics Applications Group, Inc.
For each picture element pixel in the screen, they cast a light ray through it into the scene to identify the visible surface.
At the ray-surface intersection point found, they computed the surface normal and, knowing the position of the light source, computed the brightness of the pixel in the screen.
The film showed the helicopter and a simple ground level gun emplacement. The helicopter was programmed to undergo a series of maneuvers including turns, take-offs, and landings, etc.
Unfortunately, due to the computer processing power at the time, it was an expensive, batch system. In , Scott Roth created a flip book animation in Bob Sproull 's computer graphics course at Caltech using ray tracing with a simple pinhole camera model.
The scanned pages are shown as a video on the right. Roth's computer program noted an edge point at a pixel location if the ray intersected a bounded plane different than that of its neighbors.
Of course, a ray could intersect multiple planes in space, but only the surface point closest to the camera was noted as visible. The edges are jagged because only a coarse resolution was practical with the computing power of the time-sharing DEC PDP used.
Attached to the display was a printer which would create an image of the display on [rolling] thermal paper. Although a surface normal could have been computed at every ray-surface intersection for grayscale rendering, the pixels of the display were only binary: green or black.
Roth extended the framework, introducing the term ray casting in the context of computer graphics and solid modeling.
To model shadows, transparencies, and general specularity e. Whitted produced a ray-traced film called the Compleat Angler  in while an engineer at Bell Labs.
The secondary ray is then processed as a specular ray. Until , large scale global illumination in major films using computer generated imagery was faked with additional lighting.
The Pixar film Monsters University was the first animated film to use ray tracing for all lighting and shading.
Optical ray tracing describes a method for producing visual images constructed in 3D computer graphics environments, with more photorealism than either ray casting or scanline rendering techniques.
It works by tracing a path from an imaginary eye through each pixel in a virtual screen, and calculating the color of the object visible through it.
Scenes in ray tracing are described mathematically by a programmer or by a visual artist normally using intermediary tools.
Scenes may also incorporate data from images and models captured by means such as digital photography. Typically, each ray must be tested for intersection with some subset of all the objects in the scene.
Once the nearest object has been identified, the algorithm will estimate the incoming light at the point of intersection, examine the material properties of the object, and combine this information to calculate the final color of the pixel.
Certain illumination algorithms and reflective or translucent materials may require more rays to be re-cast into the scene.
It may at first seem counterintuitive or "backward" to send rays away from the camera, rather than into it as actual light does in reality , but doing so is many orders of magnitude more efficient.
Since the overwhelming majority of light rays from a given light source do not make it directly into the viewer's eye, a "forward" simulation could potentially waste a tremendous amount of computation on light paths that are never recorded.
Therefore, the shortcut taken in ray tracing is to presuppose that a given ray intersects the view frame. After either a maximum number of reflections or a ray traveling a certain distance without intersection, the ray ceases to travel and the pixel's value is updated.
In nature, a light source emits a ray of light which travels, eventually, to a surface that interrupts its progress.
One can think of this "ray" as a stream of photons traveling along the same path. In a perfect vacuum this ray will be a straight line ignoring relativistic effects.
Any combination of four things might happen with this light ray: absorption , reflection , refraction and fluorescence. It might also reflect all or part of the light ray, in one or more directions.
If the surface has any transparent or translucent properties, it refracts a portion of the light beam into itself in a different direction while absorbing some or all of the spectrum and possibly altering the color.
Less commonly, a surface may absorb some portion of the light and fluorescently re-emit the light at a longer wavelength color in a random direction, though this is rare enough that it can be discounted from most rendering applications.
Between absorption, reflection, refraction and fluorescence, all of the incoming light must be accounted for, and no more. Some of these rays travel in such a way that they hit our eye, causing us to see the scene and so contribute to the final rendered image.
The idea behind ray casting, the predecessor to recursive ray tracing, is to trace rays from the eye, one per pixel, and find the closest object blocking the path of that ray.
Think of an image as a screen-door, with each square in the screen being a pixel. This is then the object the eye sees through that pixel.
Using the material properties and the effect of the lights in the scene, this algorithm can determine the shading of this object.
The simplifying assumption is made that if a surface faces a light, the light will reach that surface and not be blocked or in shadow.
The shading of the surface is computed using traditional 3D computer graphics shading models. One important advantage ray casting offered over older scanline algorithms was its ability to easily deal with non-planar surfaces and solids, such as cones and spheres.
If a mathematical surface can be intersected by a ray, it can be rendered using ray casting. Elaborate objects can be created by using solid modeling techniques and easily rendered.
Earlier algorithms traced rays from the eye into the scene until they hit an object, but determined the ray color without recursively tracing more rays.
Recursive ray tracing continues the process. When a ray hits a surface, additional rays may be cast because of reflection, refraction, and shadow.
Ray tracing-based rendering's popularity stems from its basis in a realistic simulation of light transport , as compared to other rendering methods, such as rasterization , which focuses more on the realistic simulation of geometry.
Effects such as reflections and shadows , which are difficult to simulate using other algorithms, are a natural result of the ray tracing algorithm.
The computational independence of each ray makes ray tracing amenable to a basic level of parallelization ,   but the divergence of ray paths makes high utilization under parallelism quite difficult to achieve in practice.
A serious disadvantage of ray tracing is performance though it can in theory be faster than traditional scanline rendering depending on scene complexity vs.
Until the late s, ray tracing in real time was usually considered impossible on consumer hardware for nontrivial tasks. Scanline algorithms and other algorithms use data coherence to share computations between pixels, while ray tracing normally starts the process anew, treating each eye ray separately.
However, this separation offers other advantages, such as the ability to shoot more rays as needed to perform spatial anti-aliasing and improve image quality where needed.
Although it does handle interreflection and optical effects such as refraction accurately, traditional ray tracing is also not necessarily photorealistic.
True photorealism occurs when the rendering equation is closely approximated or fully implemented. Implementing the rendering equation gives true photorealism, as the equation describes every physical effect of light flow.
However, this is usually infeasible given the computing resources required. The realism of all rendering methods can be evaluated as an approximation to the equation.
Ray tracing, if it is limited to Whitted's algorithm, is not necessarily the most realistic. Methods that trace rays, but include additional techniques photon mapping , path tracing , give a far more accurate simulation of real-world lighting.
The process of shooting rays from the eye to the light source to render an image is sometimes called backwards ray tracing , since it is the opposite direction photons actually travel.
However, there is confusion with this terminology. Early ray tracing was always done from the eye, and early researchers such as James Arvo used the term backwards ray tracing to mean shooting rays from the lights and gathering the results.
Therefore, it is clearer to distinguish eye-based versus light-based ray tracing. While the direct illumination is generally best sampled using eye-based ray tracing, certain indirect effects can benefit from rays generated from the lights.
Caustics are bright patterns caused by the focusing of light off a wide reflective region onto a narrow area of near- diffuse surface.
An algorithm that casts rays directly from lights onto reflective objects, tracing their paths to the eye, will better sample this phenomenon. We've seen in-game lighting effects become more and more realistic over the years, but the benefits of ray tracing are less about the light itself and more about how it interacts with the world.
Ray tracing allows for dramatically more lifelike shadows and reflections, along with much-improved translucence and scattering.
The algorithm takes into account where the light hits and calculates the interaction and interplay much like the human eye would process real light, shadows, and reflections, for example.
The way light hits objects in the world also affects which colors you see. With enough computational power available, it's possible to produce incredibly realistic CG images that are nearly indistinguishable from real life.
But that's the problem: even a well-equipped gaming PC only has so much GPU power to work with, let alone a modern game console.
Ray tracing is used extensively when developing computer graphics imagery for films and TV shows, but that's because studios can harness the power of an entire server farm or cloud computing to get the job done.
And even then, it can be a long, laborious process. Doing it on the fly has been far too taxing for existing gaming hardware.
Traditionally, video games have used rasterization instead. This is a speedier way to render computer graphics. It converts the 3D graphics into 2D pixels to display on your screen, but rasterization requires shaders to depict realistic lighting.
Right now, there are only 5 games that use Nvidia ray tracing tech, and only a few big name AAA titles. However, because this is the hot new graphics technology on the block, you can expect plenty more ray tracing games to show up over the next year or so.
