Detailed Description
This a vertex buffer created by Driver.
His pointer may be allocated on AGP Ram or VRAM. see CVertexBuffer, because it use the same flags for vertex format. IVertexBufferHard are created / deleted by IDriver. -

Lock the entire VertexBuffer.
The returned buffer is a write only buffer. (undefined result if you read it). Write note:
- for VRAM VertexBufferHard, you should write only one time, to init.
- for AGP VertexBufferHard, you should write sequentially to take full advantage of the write combiners.
-
Returns:
-
the adress of the vertex 0. Use getVertexSize(), get*Off() ... to access any part of this VertexBuffer.
Implemented in NL3D::CVertexBufferHardGLNVidia. |

Same as unlock() but give hints to driver on vertices that have changed.
Used by ATI-OpenGL drivers. NB: driver may still ignore this information, and so take into acount all vertices -
Parameters:
-
| startVert |
the fisrt vertex to update |
| endVert |
the last vertex (not included) to update => numVertices= vertEnd-vertBegin. Hence unlock() as the same effect as unlock(0, getNumVertices()); |
