WebWhatever model->GetVertices () is, that's your code, not D3D. A vertex buffer is simply an array of structs. You just make an array, put your vertices in it, and pass in the pointer and size of the array when you create the buffer. I'm not sure what you mean about reading vertices from a "stream". As a general rule, do not hold a lock across more than one frame. When working with vertex buffers, you are allowed to make multiple lock calls; however, you must ensure that the number of lock calls match the number of unlock calls.
