I think the best thing to do is to create another function in wined3d/device.c
DrawIndexedPrimitiveVB that is based on DrawIndexedPrimitiveUP but either takes
a
IWineD3DVertexBuffer or has the caller use SetVertexBuffer and then call
DrawIndexedPrimitiveVB .
e.g.
IWineD3DDeviceImpl_DrawIndexedPrimitiveVB(IWineD3DDevice *iface,
D3DPRIMITIVETYPE PrimitiveType,
UINT MinVertexIndex, UINT
NumVertices, CONST void*
pIndexData) {
/* The rest of the code making up IWineD3DDeviceImpl_DrawIndexedPrimitiveVB */
}
DirectX7_DrawIndexedPrimitiveVB(LPDIRECT3DDEVICE7 iface,
D3DPRIMITIVETYPE
d3dptPrimitiveType,
LPDIRECT3DVERTEXBUFFER7
lpD3DVertexBuf,
DWORD dwStartVertex,
DWORD dwNumVertices,
LPWORD lpwIndices,
DWORD dwIndexCount,
DWORD dwFlags) {
IWineD3DDeviceImpl_SetStreamSource(device, 0,
lpD3DVertexBuf->wineD3DVertexBuffer,
dwStartVertex * lpD3DVertexBuf->stride,
lpD3DVertexBuf->stride);
IWineD3DDeviceImpl_DrawIndexedPrimitiveVB(device, PrimitiveType,
dwIndexCount, lpwIndices);
}
Or.
IWineD3DDeviceImpl_DrawIndexedPrimitiveVB(IWineD3DDevice *iface,
D3DPRIMITIVETYPE PrimitiveType,
UINT MinVertexIndex, UINT
NumVertices,
CONST void* pIndexData,
IWineD3DVertexBuffer* pVertexBuffer,
UINT dwStartVertex, UINT Stride) {
IWineD3DDeviceImpl_SetStreamSource(device, 0, pVertexBuffer, dwStartVertex
* Stride, Stride);
/* The rest of the code making up IWineD3DDeviceImpl_DrawIndexedPrimitiveVB
*/
}
IDirect3DVertexBuffer7 need to wrap wined3dVertexBuffer.
