Step-by-step, we will go through the major building blocks required to do raytracing. So that the raytracing and raster paths share the same geometry buffers. The goal of this tutorial is to add raytracing to an existing program, Of ray tracing within an existing DirectX sample. These two posts showcase basic intergration This part one of a two-part tutorial, which deals with the initial setup Ray tracing to an existing application so that the ray tracing and raster paths
DIRECTX C BUILDER CODE
Provided code showcases a basic tutorial on integrating ray tracing within anĮxisting DirectX 12 sample using the new DXR API. Great deal of excitement among game developers. The recent integration of ray tracing into the DirectX 12 API, called DXR, has spawned a : # This may be the most platform independent comment Integration would require additional levels of abstraction. Note that forĮducational purposes all the code is contained in a very small set of files. Raytracing within an existing DirectX 12 sample, using the new DXR API. The focus of theseĭocuments and the provided code is to showcase a basic integration of Welcome to Part 1 of the DirectX 12 DXR ray tracing tutorial.

DIRECTX C BUILDER SERIES
It is already rolling out to NVIDIA's GeForce RTX series video cards, and Microsoft says the tech will be on "millions" of video cards before its console rolls around later this year. While it is exciting to see DirectX 12 Ultimate debut on the Xbox Series X, it is coming to Windows PCs first. You also get features like Sampler Feedback that increase texture quality while utilizing fewer resources, and overall you get a suite of changes that should make next-gen games run smoother.Įssentially, DirectX 12 Ultimate facilitates game makers to deliver more immersive games with higher-quality textures and life-like lighting, and with these features baked into Windows, you'll immediately start seeing a difference provided you have a video card that works with the latest version of DirectX. First and foremost is DirectX Raytracing 1.1 with more and more games picking up ray tracing, DirectX 12 Ultimate natively integrates the feature into Windows as well as Microsoft's upcoming console, the Xbox Series X.ĭirectX 12 Ultimate will make next-gen games look incredible.ĭirectX 12 Ultimate also has variable rate shading, allowing a GPU to utilize its resources more effectively for rendering in-focus objects, leading to better frame rates and more fidelity. Why does DirectX 12 Ultimate matter for gaming?ĭirectX 12 Ultimate uses the DirectX 12 foundation and includes a few new features that have emerged over the last two years.
DIRECTX C BUILDER PC
And with DirectX 12 Ultimate, Microsoft is blurring the line between the PC and Xbox Series X, making it that much easier for game developers to tailor games to each platform. So to facilitate that access, Microsoft introduced DirectX - think of DirectX as a middleman that facilitates communication between a game and a video card.ĭirectX isn't the only API protocol that's available today, but it is native to Windows - unlike the OpenGL standard - and that's what gives it an edge. That meant that games could no longer interact with low-level hardware features, and it was a problem. In the DOS days, games had direct access to video cards and the motherboard, and you could directly edit the configuration file to make changes.īut with Windows 95, Microsoft restricted access to low-level hardware as a security measure. At a basic level, DirectX allows games to "talk" to video cards. If that sounded too complex, let's break things down. DirectX is a series of application programming interfaces (API) that provide low-level access to hardware components like video cards, the sound card, and memory.
