Detailed Description

A buffer texture.

A buffer texture is similar to a one-dimensional texture. However, unlike other texture types, the texel array is not stored as part of the texture. Instead, a buffer object is attached to a buffer texture and the texel array is taken from the data store of an attached buffer object. When the contents of a buffer object's data store are modified, those changes are reflected in the contents of any buffer texture to which the buffer object is attached. Also unlike other textures, buffer textures do not have multiple image levels; only a single data store is available.
