在以前的一个帖子里，我还期待NV SDK 11早日到来。结果1月份快过去了，11没到，NV却偷偷摸摸地发布了NV SDK 10.6。更新如下：
- An improved version of Instanced Tessellation. This sample implements 3 major schemes for Approximating Catmull-Clark Subdivision Surfaces using instanced tessellation in both DX9 and DX10. In the sample, these three schemes are also compared in terms of their visual quality and performance.
- Bug fix for StencilRoutedKBuffer: the previous version would create a DX 10.1 device, resulting in corruption errors. A modification to DXUTCore prevents the DX 10.1 device from being created for the StencilRoutedKBuffer project.
- Upgrade to the June 2010 DirectX SDK: some minor fixes were required because fxc catches more HLSL errors.
- Upgrade to Microsoft Visual Studio 2008 because the 2005 version is no longer supported by Microsoft’s DirectX SDK.
