   1, D3D10 New characteristics Stream output （stream out）so Stage . It allows the GPU Bind to the pipeline SO Vertex buffer on stage V Write geometric data . All vertices output by the geometry shader are written to V in .

2,AutoDraw The premise of use must be a with ID3D10Device_STREAM_OUTPUT The vertex buffer that binds the flag value is bound to IA Input slot of stage 0 Upper time , Can be called DrawAuto Method .
