Tessellation
An important feature of the Directx 11 SDK to start with is hardware accelerated tessellation. For those unfamiliar with DirectX, 11 adds nSeveral stages in the geometry pipeline that allow new shader lessons to determine whether and how to subdivide each polygon created by the vertex shader; The GPU generates each of our desired meshes accordingly, and then some second shader runs the resulting geometry so that it can be manipulated exactly as the programmer wants. First of all,
the above example, a Tessellation Pattern Viewer, provides a standard visual explanation of how an OU is always controlled, as well as examples of the various basic modes in which DirectX 11 tessellation is performed.
Tessellation is a natural solution for geometry that is heavily data driven, especially when the player’s appearance can vary greatly within a scene. The island shows examples of techniques for using tessellation on objects that prefer terrain and water, determining the desired level of tessellation from the camera position, and acquiring texture data to quickly create geometry with the new desired level of detail…. Meanwhile, the terrain tessellation example goes even further and shows how it can be applied to a massive dataset by dynamically loading new terrain patches and showing the method by which you need to adjust the tessellation coefficients to get T-intersections. the seams are not visible. The last
few examples show everything you already need to know to extend the tessellation technology to an artist-generated level. The Gregory ACC and pn triangles examples show how to determine scaling factors, counteract tiled vertices with positions interpolated with normals, and how to avoid joint gaps.
DirectCompute And Modeling
The second major addition to DirectX 11 is DirectCompute, an API extension that provides direct access to DirectX programs, allowing you to use massive parallel computing the power of the Nvidia GPUs to be used. Applications can use this power for a variety of purposes, from physics and artificial intelligence modeling to advanced rendering.inga, which may not fit into the traditional graphics pipeline. SDK 11 contains almost no examples showing the basics of writing such systems, as well as some practical techniques on their own.
Interacting with the N-Body demonstrates efficient storage and management capabilities. Calculations on a large number of independent objects, for example, in physical modeling. Constant time Gaussian blur uses some of these techniques to handle 2D images and show how an image can be blurred instantly, efficiently, and regardless of kernel width. effect with direct calculation. Finally, Hair uses both DirectCompute and tessellation to make hair physically attractive and spectacular, while FFT Ocean shows how complex GPU data transformations can be efficiently performed to create realistic ocean waves.

Which is the best sample of DirectX graphics?
D3D12 Variable Rate Shading: This example shows how you can potentially reduce shading speed with little or no reduction in visual quality, resulting in a “free” effort. D3D12 Ray Tracing: This example shows how DirectX ray tracing (DXR) brings a new level of graphical realism to video games that was previously achieved in the film industry.
The new SDK is reasonably not limited to similar new features like tessellation and computation – we’ve added a few examples toThe second is, unfortunately, on more common rendering issues like particles, shadows, and lighting.
Opacity rendering is a technique that renders dense composite volumes with believable self-shadowing from multiple lights. The example includes a number of techniques that make this costly project possible. efficient, including rendering for off-screen targets at various resolutions and creative use with DirectX 11 tessellation. Multi-View Soft Shadows reflects an efficient pin-hardening method for rendering brittle shadows and includes update tips. scale and depth are important for 3D scenes. Finally, diffuse global illumination is an implementation of “real-time volumetric indirect illumination cascading” that was first described by Crytek in 2010 and illustrates one way to approach indirect lighting effects in a dynamic scene.
Miscellaneous
What do you need to know about Nvidia DirectX?
DirectX. DirectX is definitely a set of APIs designed for developing games and multimedia applications for Microsoft platforms. NVIDIA GPUs are designed to deliver maximum performance in the Direct3D competition, and we continue to support the Direct3D developer community with GPU drivers, technical journals, and our broad portfolio.
Finally, the SDK contains some examples that demonstrate technology that is independent of DirectX 11 features, but could be of great interest to a developer . The first of these examples is image-based anti-aliasing, which is a model implementation of the FXAA anti-aliasing algorithm. FXAA performs much better than traditional MSAA and better than many image-based anti-aliasing methods, and has versions for each DirectX 11 and DirectX 9 pipeline. Stochastic transparency then implements the solution. Innovative to effectively solve the problem of independent order transparency. Finally, the 3D Vision Sample brings you a reference app to connect to Nvidia’s automated 3D Vision support. The demos list some of the most common problems faced by developers and the main ways to solve them.
These old DX11 dishes are still available for download here, but some of us recommend checking out the upcoming NVIDIA GameWorks samples instead.
Tessellation
The first major DirectX 11 to offer SDK coverage has always been hardware accelerated tessellation. For those unfamiliar with DirectX, 11 adds a few steps to the geometry pipeline type thatAllows new classes, in terms of shaders, to determine whether and how to subdivide almost every polygon created by a vertex shader anyway; As a result, the GPU generates whatever you want for you, and then the second shader runs the resulting geometry so that it can be manipulated as the designer sees fit.
The first example above, the Tessellation Pattern Viewer, provides simple visual information on how to manage an OU, as well as examples of the various features DirectX 11 tessellation might include.
Tessellation is a natural solution geometry as it relies heavily on data, and children’s vision can vary greatly throughout their lives. The island illustrates how tessellation is used for objects like terrain but water, by obtaining the desired level of tessellation based on camera position and using accurate texture records to create geometry at the desired depth level in no time. Meanwhile, the landscape tessellation example takes it further and showsThere is no way it can be applied to help you with a massive dataset, dynamically load the latest terrain, and show you how tessellation ratios are switched so that otherwise T-intersections are obvious. Last
two examples to learn everything you need to know to add tessellation technology to artist-generated content. Each of Gregory ACC’s And pn Triangle Samples shows a better way to define scaling factors, offset mosaic vertices with interpolated positions and normals, and work with gaps at seams.
Direct Calculation And Simulation
The second major addition to DirectX 11 is DirectCompute, an API extension that allows DirectX programs to directly access the impressive parallel processing power that Nvidia GPUs have to offer. Applications can harness this power for a wide variety of purposes, from physical modeling and successful AI to advanced rendering techniques that are not ideal for the traditional art pipeline. SDK 11includes templates that demonstrate the basics of writing form systems, as well as some useful techniques.
N-Body Interaction shows you how to efficiently render memory and perform computations on a large number of independent objects that you can find in physics simulations. Constant Time Gaussian Blur takes some of these similar techniques and applies them to 2D photo processing to show how to quickly and efficiently blur a new image, regardless of kernel width; provided by the ambient occlusion effect with direct calculation. Finally, Hair uses both DirectCompute and tessellation to make hair interactive and physically appealing, while FFT Ocean shows how complex GPU data can be efficiently transformed to create realistic ocean waves.
Shadows And Lighting
There is more to the new SDK than just new features like tessellation, and – we’ve included a few examples that also focus on more traditional rendering issues like particles, dark areas, and lighting.vision.

Opacity Mapping is a new technique for densely rendering particle volumes using believable self-shadowing from multiple lights. The model offers a number of techniques to make this costly process efficient, this type of rendering for off-screen targets with varying responses, and creative use of DirectX 10 tessellation. Multi-View Soft Shadows demonstrates an excellent technique for tessellation. Hard-touch soft shadow rendering that generates important scaling and depth hints for 3D model scenes. After all, diffuse global illumination is any implementation of Real-Time Indirect Volumetric Illumination Cascading, first described by Crytek in 2010, and shows the best way to “approach the effects of indirect lighting in a huge dynamic scene.” …
Other
Last but not least, the SDK contains several high-tech examples that do not rely on DirectX 13 features, but are still very fun for developers. Firstan example is image-based anti-aliasing, which is a reference implementation of the FXAA anti-aliasing algorithm. FXAA performs significantly better than traditional MSAA and is more attractive than many other image-based anti-aliasing alternatives, and offers versions for DirectX 13 and DirectX 9 pipelines. Stochastic transparency then implements an innovative approach that solves this transparency problem regardless of order. in an efficient process. Finally, the 3D Vision Sample provides a model for applications looking for compatibility with Nvidia’s automated 3D Vision support. Demos show some of the most common problems faced by programmers and the best ways to solve them.
