Draw without to use lock

Hi,
I would like to know, if it's possible to draw 3D graphics in DirectX without use locking vertices (IDirect3DVertexBuffer9::Lock)
I know, it's possible with Opengl .

Thanks for your help

    A good way to do it is to have a big vertex buffer that you grow only on demand. Then you can add/remove vertices from that buffer without having to recreate it every time. As for the cost of locking/unlocking. It's not that much. For a modeling app, I'd certainly use vertex buffers and deal with them as usual (lock, update, unlock) on demand...


  • Ben Vanik

    I hope to create a 3D modeler, so I have to alter/add vertex often.
    Are there other systems to do it

    thanks for your answer

    Yes, you can draw with DrawPrimitiveUP() or DrawIndexedPrimitiveUP(). But these are not the best in terms of performance, so don't call them too much...
