\title Interoperation between OpenCL and OpenGL
The QCLContextGL class extends QCLContext and provides
additional functions that are useful when working with OpenGL
contexts, textures, and buffers. QCLContextGL objects must
be created with a current QGLContext to define the specific
OpenGL context to interoperate with:
\code
QGLWidget glw;
glw.makeCurrent();
QCLContextGL context;
if (!context.create())
qFatal("Could not create the OpenCL context");
\endcode
The above code will select the first QCLDevice::GPU device
that is found on the system, and enable OpenGL object sharing
if the \c{cl_khr_gl_sharing} or \c{cl_apple_gl_sharing}
extension is present. If there is no QCLDevice::GPU, then
QCLDevice::Default will be used instead.
If the OpenCL implementation does not support interoperation
with OpenGL, then the classes listed below will still be present
in the final library, but their functionality and performance
will be reduced.
The QCLContextGL::supportsObjectSharing() function can be used
to determine if the OpenCL implementation can interoperate with
the system's OpenGL implementation.
The following classes are used to enable interoperation between
OpenCL and OpenGL:
