public class EXTMemoryObject extends java.lang.Object
Native bindings to the EXT_memory_object extension.The Vulkan API introduces the concept of explicit memory objects and reusable synchronization objects. This extension brings those concepts to the OpenGL API via two new object types:
- Memory objects
- Semaphores
Rather than allocating memory as a response to object allocation, memory allocation and binding are two separate operations in Vulkan. This extension allows an OpenGL application to import a Vulkan memory object, and to bind textures and/or buffer objects to it.
No methods to import memory objects are defined here. Separate platform-specific extensions are defined for this purpose.
Semaphores are synchronization primitives that can be waited on and signaled only by the GPU, or in GL terms, in the GL server. They are similar in concept to GL's "sync" objects and EGL's "EGLSync" objects, but different enough that compatibilities between the two are difficult to derive.
Rather than attempt to map Vulkan semaphores on to GL/EGL sync objects to achieve interoperability, this extension introduces a new object, GL semaphores, that map directly to the semantics of Vulkan semaphores. To achieve full image and buffer memory coherence with a Vulkan driver, the commands that manipulate semaphores also allow external usage information to be imported and exported.
