Class EXTBufferStorage

java.lang.Object

org.lwjgl.opengles.EXTBufferStorage

public class EXTBufferStorage
extends java.lang.Object

Native bindings to the EXT_buffer_storage extension.

OpenGL ES has long supported buffer objects as a means of storing data that may be used to source vertex attributes, pixel data for textures, uniforms and other elements. In un-extended ES, buffer data stores are mutable - that is, they may be de-allocated or resized while they are in use. The GL_EXT_texture_storage extension added immutable storage for texture objects (and was subsequently incorporated into OpenGL ES 3.0). This extension further applies the concept of immutable storage to buffer objects. If an implementation is aware of a buffer's immutability, it may be able to make certain assumptions or apply particular optimizations in order to increase performance or reliability.

Furthermore, this extension allows applications to pass additional information about a requested allocation to the implementation which it may use to select memory heaps, caching behavior or allocation strategies.

Finally, this extension introduces the concept of persistent client mappings of buffer objects, which allow clients to retain pointers to a buffer's data store returned as the result of a mapping, and to issue drawing commands while those mappings are in place.

Requires GLES 3.1.
