[section:interop Interoperability]
Boost.Compute provides a number of facilities to ease interoperability with
other C and C++ libraries including [@http://en.wikipedia.org/wiki/OpenGL
OpenGL], [@http://opencv.org/ OpenCV], [@http://eigen.tuxfamily.org Eigen],
[@http://qt-project.org/ Qt], and [@http://vtk.org/ VTK].
All of the interop headers are located in the `<boost/compute/interop/...>`
directory.
[section OpenGL]
OpenGL is a standard API for 3D graphics and closely related to OpenCL.
Boost.Compute provides an easy way to create a shared OpenCL/OpenGL context
via the [funcref boost::compute::opengl_create_shared_context
opengl_create_shared_context()] function. This creates a Boost.Compute
[classref boost::compute::context context] object which can be used to create
OpenCL memory buffers corresponding to OpenGL memory objects (such as VBOs).
This allows for OpenCL kernels to read and write data which is then used
directly for rendering with OpenGL.
Boost.Compute provides a few classes to manage OpenGL objects and make them
accessible to OpenCL. These include [classref boost::compute::opengl_buffer
opengl_buffer] (for OpenGL memory objects) and [classref
boost::compute::opengl_texture opengl_texture] (for OpenGL texture objects).
Control of shared OpenCL/OpenGL memory objects is transfered between OpenCL and
OpenGL using the [funcref boost::compute::opengl_enqueue_acquire_gl_objects
opengl_enqueue_acquire_gl_objects()] and [funcref
boost::compute::opengl_enqueue_release_gl_objects
opengl_enqueue_release_gl_objects()] functions.
See the OpenCL documentation for the
[@https://www.khronos.org/registry/cl/sdk/1.2/docs/man/xhtml/cl_khr_gl_sharing.html
cl_khr_gl_sharing] extension for more information.
