<hr><a name="_details"></a><h2>Detailed Description</h2>
This section describes the OpenGL interoperability functions of the CUDA runtime application programming interface. Note that mapping of OpenGL resources is performed with the graphics API agnostic, resource mapping interface described in <a class="el" href="group__CUDART__INTEROP.html">Graphics Interopability</a>. </div>
