Reports the number of triangles that have been processed and clipped by the runtime's software vertex processing.
typedef struct D3DDEVINFO_D3DVERTEXSTATS { DWORD NumRenderedTriangles; DWORD NumRenderedTriangles; DWORD NumExtraClippingTriangles; } D3DDEVINFO_D3DVERTEXSTATS, *LPD3DDEVINFO_D3DVERTEXSTATS;
Use the debug runtime and software vertex processing to get the number of non-clipped and clipped primitives for a particular scene. Primitives will typically be clipped based on a guard band (if one is present). The clipping guard band is set with parameters such as GuardBandLeft in D3DCAPS9.
