Boost C++ Libraries of the most highly regarded and expertly designed C++ library projects in the world. Herb Sutter and Andrei Alexandrescu, C++ Coding Standards

This is the documentation for an old version of Boost. Click here to view this page for the latest version.



Boost.Compute provides a number of facilities to ease interoperability with other C and C++ libraries including OpenGL, OpenCV, Eigen, Qt, and VTK.

All of the interop headers are located in the <boost/compute/interop/...> directory.

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 opengl_create_shared_context() function. This creates a Boost.Compute 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 opengl_buffer (for OpenGL memory objects) and opengl_texture (for OpenGL texture objects).

Control of shared OpenCL/OpenGL memory objects is transfered between OpenCL and OpenGL using the opengl_enqueue_acquire_gl_objects() and opengl_enqueue_release_gl_objects() functions.

See the OpenCL documentation for the cl_khr_gl_sharing extension for more information.
