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.

virtual void* NL3D::IVertexBufferHard::lock (   )  [pure virtual]
 

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, NL3D::CVertexBufferHardGLATI, and NL3D::CVertexBufferHardGLMapObjectATI.

virtual void NL3D::IVertexBufferHard::lockHintStatic (  bool  staticLock  )  [pure virtual]
 

Indicate what kind of lock to be done on this VertexBuffer (whatever AGP or VRAM buffer) User should set to true if the VBHard is static: nevers change or very rarely. NVidia OpenGL implementation: "Static lock" are slower, but no fences are inserted after a render with this VVBHard, hence, no slowdown because 1/ of fence overhead insertion 2/ of NVidia swapBuffers() and fence issues on GeForce2 cards. Default is false

Implemented in NL3D::CVertexBufferHardGLNVidia, NL3D::CVertexBufferHardGLATI, and NL3D::CVertexBufferHardGLMapObjectATI.

virtual void NL3D::IVertexBufferHard::unlock (  uint  startVert,
uint  endVert
)  [pure virtual]
 

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());

Implemented in NL3D::CVertexBufferHardGLNVidia, NL3D::CVertexBufferHardGLATI, and NL3D::CVertexBufferHardGLMapObjectATI.

virtual void NL3D::IVertexBufferHard::unlock (   )  [pure virtual]
 

UnLock the VertexBuffer so the Gfx card can now use it.

Implemented in NL3D::CVertexBufferHardGLNVidia, NL3D::CVertexBufferHardGLATI, and NL3D::CVertexBufferHardGLMapObjectATI.
