DX11 will be released with Windows 7 The first DEMO show

NVIDIA not only promoted its latest technology on NVISION 08, but also fully explained the latest features of Microsoft DirectX 11 core part Direct3D 11, and the first DEMO demonstration.

The latest news said that Microsoft will release the first preview version of DX11 in November this year, and the official version will be released along with Windows 7, which is the end of 2009 or early 2010.

Unfortunately, although NVIDIA gave a live demonstration and detailed description of DX11, but did not disclose the specific technical details of DEMO, only to see that Tessellation is one of the key points, which is also the DX11 Direct3D 11 technology. The key point.

Here are some introductions to DX11:

The main purpose of D3D 11 is to improve scalability, improve development experience, expand GPU capabilities, and improve performance. It is a superset of D3D 10/10.1, adding some new features, supporting Windows Vista and subsequent operating systems, and supporting DX10/10.1 level hardware.

The main new technologies of D3D 11: Tessellation, Compute Shader, multi-threading, dynamic Shader association, improved texture compression … …

The trend of character creation is becoming more and more complex, with more and more triangles and polygons, which poses greater challenges to rendering pipelines and input and output, and therefore require more advanced surface rendering techniques.

D3D 11 adds three new rendering processes: Hull Shader, Tessellation, and Domain Shader.

After adding three processes, D3D 11's rendering pipeline is richer and more complex.

The following are some examples of surface treatment pipelines involving Vertex Shader, Hull Shader, Tessellation, and Domain Shader.

The main purpose of Tessellation technology is to provide smoother surface contours and richer animations at a lower cost, improve image quality scalability for different hardware configurations, and improve performance in all aspects. Let the artist get the desired rendering effect.

In addition to the three new rendering stages, D3D 11 also includes the Compute Shader.

Compute Shader can post-process images and then output the final image.

Compute Shaders come in many ways, such as images and post-processors, A-Buffer/OIT, ray tracing and radiation, physics, artificial intelligence, and more.

In summary, Compute Shader provides more general-purpose algorithms, transparent parallel processing models, and comprehensive support for hardware from different vendors.

Of course, D3D 11 has many other new features, and there are dozens of simple ones.
