Functionality in this section is only available when PyOpenCL is compiled with GL support. See have_gl().

New in version 0.91.

pyopencl.have_gl()

Return True if PyOpenCL was compiled with OpenGL interoperability, otherwise False.

pyopencl.get_gl_sharing_context_properties()

Return a list of context_properties that will allow a newly created context to share the currently active GL context.

pyopencl.get_apple_cgl_share_group()

Get share group handle for current CGL context.

Apple OS X only.

New in version 2011.1.

class pyopencl.GLBuffer(context, flags, bufobj)

GLBuffer inherits from MemoryObject.

gl_object
class pyopencl.GLRenderBuffer(context, flags, bufobj)

GLRenderBuffer inherits from MemoryObject.

gl_object
class pyopencl.GLTexture(context, flags, texture_target, miplevel, texture, dims)

GLTexture inherits from Image. Only available in OpenCL 1.2 and newer.

gl_object
get_gl_texture_info(param)

See gl_texture_info for values of param. Only available when PyOpenCL is compiled with GL support. See have_gl().

pyopencl.enqueue_acquire_gl_objects(queue, mem_objects, wait_for=None)

mem_objects is a list of MemoryObject instances. Returns a new pyopencl.Event. wait_for may either be None or a list of pyopencl.Event instances for whose completion this command waits before starting exeuction.

pyopencl.enqueue_release_gl_objects(queue, mem_objects, wait_for=None)

mem_objects is a list of MemoryObject instances. Returns a new pyopencl.Event. wait_for may either be None or a list of pyopencl.Event instances for whose completion this command waits before starting exeuction.

pyopencl.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 Context constructor for the meaning of properties and gl_context_info for param_name.

Changed in version 2011.2: Accepts the platform argument. Using platform equal to None is deprecated as of PyOpenCL 2011.2.
