| '''OpenGL extension IBM.static_data |
| |
| This module customises the behaviour of the |
| OpenGL.raw.GL.IBM.static_data to provide a more |
| Python-friendly API |
| |
| Overview (from the spec) |
| |
| The OpenGL specification requires that data be bound at call time. The |
| IBM_static_data extension relaxes the bind-at-call semantics allowing |
| an implementation to dereference pointers some time after the |
| corresponding calls. |
| |
| Because of the bind-at-call sematics of standard OpenGL, an |
| implementation is required to either copy or fully process data at the |
| time it is provided by the application. Copying data substantially |
| increases the demands on the memory subsystem; processing the data may |
| result in ineffective amortization of fixed costs. Neither copying nor |
| processing allows multiple rendering threads to operate on the original |
| data. |
| |
| The official definition of this extension is available here: |
| http://www.opengl.org/registry/specs/IBM/static_data.txt |
