Specifies the expected usage pattern of the data store.

Variants

StreamDraw

The data store contents will be modified once and used at most a few times. The data store contents are modified by the application, and used as the source for GL drawing and image specification commands.

StreamRead

The data store contents will be modified once and used at most a few times. The data store contents are modified by reading data from the GL, and used to return that data when queried by the application.

StreamCopy

The data store contents will be modified once and used at most a few times. The data store contents are modified by reading data from the GL, and used as the source for GL drawing and image specification commands.

StaticDraw

The data store contents will be modified once and used many times. The data store contents are modified by the application, and used as the source for GL drawing and image specification commands.

StaticRead

The data store contents will be modified once and used many times. The data store contents are modified by reading data from the GL, and used to return that data when queried by the application.

StaticCopy

The data store contents will be modified once and used many times. The data store contents are modified by reading data from the GL, and used as the source for GL drawing and image specification commands.

DynamicDraw

The data store contents will be modified repeatedly and used many times. The data store contents are modified by the application, and used as the source for GL drawing and image specification commands.

DynamicRead

The data store contents will be modified repeatedly and used many times. The data store contents are modified by reading data from the GL, and used to return that data when queried by the application.

DynamicCopy

The data store contents will be modified repeatedly and used many times. The data store contents are modified by reading data from the GL, and used as the source for GL drawing and image specification commands.
