  Direct3D 11 (and the hardware that supports it) includes a lot of new functionality for programmers, but one of the most interesting and powerful additions is Tessellation. This feature has been used in numerous high profile titles and is a great way to upgrade your visuals without an unreasonable amount of extra content effort. Arguably the easiest way to leverage GPU-based tessellation is computing dynamic LODs for your geometry on the fly. For the most part this is pretty...

Conventional OpenGL supports rendering images (pixel rectangles and bitmaps) and simple geometric primitives (points, lines, polygons). NVIDIA's NV_path_rendering OpenGL extension adds a new rendering paradigm, known as path rendering, for rendering filled and stroked paths. Path rendering approach is not novel-but rather a standard part of most resolution-independent 2D rendering systems such as Adobe’s PostScript, PDF, and Flash; Microsoft’s TrueType fonts, Direct2D, Office drawings,...

These older DX11 samples are still available for download here although we suggest you check out the new NVIDIA GameWorks Samples instead Tessellation   The first major DirectX 11 feature that the SDK covers is hardware-accellerated tessellation. For those not familiar, DirectX 11 adds several stages to the geometry pipeline, which allow new classes of shaders to determine if and how each polygon produced by the Vertex Shader should be subdivided; the GPU generates the desired mesh...
