+    OpenGL ES Extension #329
+
+Dependencies
+
+    Written against the OpenGL 4.6 and OpenGL ES 3.2 specifications
+    including ARB_sparse_texture and ARB_sparse_buffer.
+
+    GL_NV_memory_object_sparse requires GL_EXT_memory_object,
+    ARB_sparse_texture and/or ARB_sparse_buffer or a version of
+    OpenGL or OpenGL ES that incorporates it.
+
+    NV_memory_object_sparse interacts with ARB_direct_state_access (OpenGL)
+    when OpenGL < 4.6 is used.
+
+    ARB_sparse_texture (OpenGL) interacts with GL_EXT_memory_object_sparse.
+    ARB_sparse_buffer (OpenGL) interacts with GL_EXT_memory_object_sparse.
+    EXT_sparse_texture (OpenGL ES) interacts with GL_EXT_memory_object_sparse.
+
+Overview
+
+    This extension adds sparse support to EXT_memory_object extension.
+

+Additions to Chapter 6 of the OpenGL 4.4 (core) Specification (Buffer Objects)
+
+    In Section 6.2, "Creating and Modifying Buffer Object Data Stores", add
+    the following add the following to the end of the description of
+    BufferSubData:
+
+    If NV_memory_object_sparse is supported, additionally, the commands
+
+        void BufferPageCommitmentMemNV(enum target,
+                                       intptr offset, sizeiptr size,
+                                       uint memory, uint64 offset,
+                                       boolean commit);
+
+        void NamedBufferPageCommitmentMemNV(uint buffer,
+                                            intptr offset,
+                                            sizeiptr size,
+                                            uint memory, uint64 offset,
+                                            boolean commit);
+
+    behaves similarly to BufferPageCommitmentARB and
+    NamedBufferPageCommitmentMemARB except that the pages of the sparse buffer
+    are bound to the memory specified by <memory> and <offset>.
+
+    Errors (additionally to non-Mem variants)
+
+      An INVALID_OPERATION error is generated if <memory> is not the name of
+      an existing memory object.
+
+      An INVALID_OPERATION error is generated if <offset> + <size> exceeds the
+      size of the memory object.
+
+    Add the following to end of subsection 8.20.2. "Controlling Sparse Texture
+    Commitment":
+
+    If NV_memory_object_sparse is supported, additionally, the commands
+
+        void TexPageCommitmentMemNV(enum target,
+                                    int layer, int level,
+                                    int xoffset, int yoffset, int zoffset,
+                                    sizei width, sizei height, sizei depth,
+                                    uint memory, uint64 offset,
+                                    boolean commit);
+
+        void TexturePageCommitmentMemNV(uint texture,
+                                        int layer, int level,
+                                        int xoffset, int yoffset, int zoffset,
+                                        sizei width, sizei height, sizei depth,
+                                        uint memory, uint64 offset,
+                                        boolean commit);
+
+    behaves similarly to TexPageCommitmentMemARB and
+    TexturePageCommitmentEXT except that the tiles of the sparse texture
+    are bound to the memory specified by <memory> and <offset>.
+
+    <layer> indicates the layer of a texture array or cube texture,
+    <zoffset> must be 0 and <depth> must 1 in this case. For other textures
+    <layer> must be 0.
+
+    Errors (additionally to non-Mem variants)
+
+      An INVALID_OPERATION error is generated if <memory> is not the name of
+      an existing memory object.
+
+      An INVALID_OPERATION error is generated if <memory> is dedicated or
+      imported from a non-opaque handle.
+
+      An INVALID_OPERATION error is generated if <offset> plus the number of
+      bytes required for the tiles to commit exceeds the size of the memory
+      object.
+
+      An INVALID_VALUE error is generated if <layer> is not 0 and the texture
+      neither a texture array or a cube texture.
+
+      An INVALID_VALUE error is generated if <zoffset> is not 0 or <depth> is
+      not 1 if the texture is a texture array or a cube texture.
+
+      An INVALID_VALUE error is generated if <layer> is greater or equal than
+      the number of layers of the texture array.
+
+      An INVALID_VALUE error is generated if <layer> is greater or equal than
+      6 in case of a cube texture.
+
+Dependencies on EXT_direct_state_access
+
+    If EXT_direct_state_access is not supported, remove references to the
+    NamedBufferPageCommitmentMemNV and TexturePageCommitmentMemNV commands
+    added by this extension.
+
+Issues
+
+    (1) Should we a 'aspect' parameter to the new gl.*CommitMemNV() functions?
+
+    RESOLVED: No. This can be deferred to a future EXT extension because there
+              is currently no multi-planar texture support in GL and metadata
+              isn't required for NVIDIA hardware.
