This creates a Boost.Compute 26[classref boost::compute::context context] object which can be used to create 27OpenCL memory buffers corresponding to OpenGL memory objects (such as VBOs). 28This allows for OpenCL kernels to read and write data which is then used 29directly for rendering with OpenGL. 30 31Boost.Compute provides a few classes to manage OpenGL objects and make them 32accessible to OpenCL. These include [classref boost::compute::opengl_buffer 33opengl_buffer] (for OpenGL memory objects) and [classref 34boost::compute::opengl_texture opengl_texture] (for OpenGL texture objects). 35 36Control of shared OpenCL/OpenGL memory objects is transfered between OpenCL and 37OpenGL using the [funcref boost::compute::opengl_enqueue_acquire_gl_objects 38opengl_enqueue_acquire_gl_objects()] and [funcref 39boost::compute::opengl_enqueue_release_gl_objects 40opengl_enqueue_release_gl_objects()] functions. 41 42See the OpenCL documentation for the 43[@https://www.khronos.org/registry/cl/sdk/1.2/docs/man/xhtml/cl_khr_gl_sharing.html 44cl_khr_gl_sharing] extension for more information. 45 46[endsect] [/ opengl] 47 48[endsect] [/ interop ] 49
