WebHolds extended parameters for a hardware buffer. NvBufferSession typedef struct _NvBufferSession* NvBufferSession Holds an opaque NvBuffer session type required for parallel buffer tranformations and compositions. Operations using a single session are scheduled sequentially, after the previous operation finishes. WebOverview Extension EXT_buffer_storage introduced immutable storage buffers to OpenGL ES. This extension allows the data store for an immutable buffer to be sourced from an external EGLClientBuffer, allowing sharing of EGL client buffers across APIs, across processes, and across different processing cores such as the GPU, CPU, and DSP.
