| The OpenCL functions enabled by the <code class="function">cl_khr_d3d10_sharing</code> extension allow applications |
| to use Direct3D 10 resources as OpenCL memory objects. This allows efficient sharing of data |
| between OpenCL and Direct3D 10. The OpenCL API may be used to execute kernels that read and/or |
| write memory objects that are also Direct3D 10 resources. An OpenCL image object may be created |
| from a Direct3D 10 texture resource. An OpenCL buffer object may be created from a Direct3D 10 |
| buffer resource. OpenCL memory objects may be created from Direct3D 10 objects if and only if the |
| OpenCL context has been created from a Direct3D 10 device. |
