Direct3D 10.1 introduces "feature levels" 10_0 and 10_1, which allow use of only the hardware features defined in the specified version of Direct3D API. Direct3D 11 adds level 11_0 and "10 Level 9" - a subset of the Direct3D 10 API designed to run on Direct3D 9 hardware, which has three feature levels (9_1, 9_2 and 9_3) grouped by common ...
Direct3D is a graphics application programming interface (API) for Microsoft Windows. Part of DirectX, Direct3D is used to render three-dimensional graphics in applications where performance is important, such as games. Direct3D uses hardware acceleration if it is available on the graphics card, allowing for hardware acceleration of the entire ...
There are seven feature levels provided by D3D_FEATURE_LEVEL structure; levels 9_1, 9_2 and 9_3 (collectively known as Direct3D 11 Level 5) re-encapsulate various features of popular Direct3D 9 cards conforming to Shader Model 2.0, while levels 10_0, 10_1, 11_0 and 11_1 refer to respective versions of the Direct3D API.
The High-Level Shader Language [1] or High-Level Shading Language [2] ( HLSL) is a proprietary shading language developed by Microsoft for the Direct3D 9 API to augment the shader assembly language, and went on to become the required shading language for the unified shader model of Direct3D 10 and higher. HLSL is analogous to the GLSL shading ...
OpenGL and Direct3D are both implemented in the display device driver. A significant difference however is that Direct3D implements the API in a common runtime (supplied by Microsoft), which in turn talks to a low-level device driver interface (DDI). With OpenGL, every vendor implements the full API in the driver.
DirectX 10 introduced features allowing shaders to access individual samples in multisampled render targets (and depth buffers in version 10.1), giving users of this API access to hardware anti-aliasing in deferred shading. These features also allow them to correctly apply HDR luminance mapping to anti-aliased edges, where in earlier versions ...
The GeForce 200 series introduced Nvidia's second generation of Tesla (microarchitecture), Nvidia's unified shader architecture; the first major update to it since introduced with the GeForce 8 series . The GeForce GTX 280 and GTX 260 are based on the same processor core. During the manufacturing process, GTX chips were binned and separated ...
Other notable features include: Enhanced Metal Graphics Rendering Engine with Direct3D 10.1, updated user interface and application menu, improved Fusion REST API, one-click SSH, new vSphere view, VMware Virtual Hardware Platform version 16.
