OpenCL Runtime: OpenGL Interoperability
=======================================
.. currentmodule:: pyopencl
Functionality in this section is only available when PyOpenCL is compiled
with GL support. See :func:`have_gl`.
.. versionadded:: 0.91
.. function:: have_gl()
Return *True* if PyOpenCL was compiled with OpenGL interoperability, otherwise *False*.
.. function:: get_gl_sharing_context_properties()
Return a :class:`list` of :class:`context_properties` that will
allow a newly created context to share the currently active GL
context.
.. function:: get_apple_cgl_share_group()
Get share group handle for current CGL context.
Apple OS X only.
.. versionadded:: 2011.1
.. class:: GLBuffer(context, flags, bufobj)
:class:`GLBuffer` inherits from :class:`MemoryObject`.
.. attribute:: gl_object
.. class:: GLRenderBuffer(context, flags, bufobj)
:class:`GLRenderBuffer` inherits from :class:`MemoryObject`.
.. attribute:: gl_object
.. class:: GLTexture(context, flags, texture_target, miplevel, texture, dims)
:class:`GLTexture` inherits from :class:`Image`. Only available in OpenCL 1.2
and newer.
.. attribute:: gl_object
.. method:: get_gl_texture_info(param)
See :class:`gl_texture_info` for values of *param*. Only available when PyOpenCL is compiled with GL support. See :func:`have_gl`.
.. function:: enqueue_acquire_gl_objects(queue, mem_objects, wait_for=None)
*mem_objects* is a list of :class:`MemoryObject` instances.
|std-enqueue-blurb|
.. function:: enqueue_release_gl_objects(queue, mem_objects, wait_for=None)
*mem_objects* is a list of :class:`MemoryObject` instances. |std-enqueue-blurb|
.. function:: get_gl_context_info_khr(properties, param_name, platform=None)
Get information on which CL device corresponds to a given
GL/EGL/WGL/CGL device.
See the :class:`Context` constructor for the meaning of
*properties* and :class:`gl_context_info` for *param_name*.
.. versionchanged:: 2011.2
Accepts the *platform* argument. Using *platform* equal to None is
deprecated as of PyOpenCL 2011.2.
