In each release of our SDK you will find numerous code samples, complete with carefully commented source code, whitepapers, and videos to help you take advantage of the latest technology from NVIDIA.
This code is released free of charge for use in derivative works, whether academic, commercial, or personal (Full License).
Cg 2.0 Toolkit is required to compile some code samples. Please obtain the Cg 2.0 Toolkit from the full OpenGL SDK 10 installer.

Instanced Tessellation 
This example shows how to use bindable uniform buffers and draw instanced in order to render tessellated curved surfaces. The vertices and the indices are stored in buffer objects and bound to the shader. Patches are drawn by rendering a single tessellated quad multiple times, using instancing to do this in a single call and the instance id to index the index buffer. Indices are stored as integers using the integer support in gpu shader4.
This is idea is based on the Generic Mesh Refinement On GPU paper. |

Simple Texture Buffer Object
Simple Texture Buffer Object demonstrates how a texture buffer object can be used as a source for additional array data for a shader. In this sample, the arrays are used in place of regular vertex arrays to allow more comlicated indexing than OpenGL allows. |
