    Equivalent extension WGL_NV_DX_interop for AMD?

      Hi,

      Nvidia has been speaking about OGL-DX interop since last year GTC 2009 and now has just released WGL_NV_DX_interop spec and drivers supporting it..

      Seems an interesting extension which useful cases as:

      also could be good for an OpenGL video player using DXVA GPU video decode and mapping d3d texture with video frames to OGL textures all without the host to comunicate..

      So the question is  AMD interested and going to implement that on OpenGL drivers?

      Also if not you could enable similar functionality via OpenCL allowing to create an OpenCL context with simultaneous OpenGL and Direct3D interop.. Your OpenCL driver allows for OGL or D3D interop but not simultaneous and that could be using current API using in clCreateContext both CL_GL_CONTEXT_KHR, CL_WGL_HDC_KHR and CL_CONTEXT_D3D10_DEVICE_KHR ..

      currently OpenCL seems to use only first info..

      Thanks.
