Hello,
I would like to ask if it is possible to do Inter-Process Communication (IPC) in OpenGL. I have an OpenGL texture in application A, which I want to share to application B using shared memory. So far, we manage to do this using DirectX 11, which exports the texture in A, and is imported in B using OpenGL. Specifically, we use a combination of the functions in the EXT_external_objects
and EXT_external_objects_win32
extensions (e.g. ImportMemoryWin32Handle/NameEXT
).
Now, I would like to export an image from OpenGL. I know that in Vulkan (with the proper extensions), you can export a block of memory and get an OS-specific shared handle to it, which is usable across processes. Is there something similar exclusively in OpenGL only? Or, is there an “export” counterpart of ImportMemoryWin32Handle/NameEXT
?
