Allow applications to use OpenGL buffer, texture and renderbuffer objects as OpenCL memory objects.

cl_khr_gl_sharing

Description

gl_sharingInc.adoc

Notes

If the cl_khr_mipmap_image, extension is supported by the OpenCL device, the cl_khr_gl_sharing extension adds support for creating a mip-mapped CL image from a mip-mapped GL texture.

To create a mip-mapped CL image from a mip-mapped GL texture, the miplevel argument to clCreateFromGLTexture, should be a negative value. If miplevel is a negative value then a CL mipmapped image object is created from a mipmapped GL texture object instead of a CL image object for a specific miplevel of a GL texture.

Note	For a detailed description of how the level of detail is computed, please refer to section 3.9.7 of the OpenGL 3.0 specification.
