| | '''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: |
