TD3DCLIPSTATUS
[ component ]
The TD3DClipStatus component wraps the DirectX D3DCLIPSTATUS9 structure which defines the union and intersection settings for clipping. This component is used by the TDx9_3DDevice::GetClipStatus() and TDx9_3DDevice::SetClipStatus() methods for holding clipping settings. When vertex processing with clipping enabled (TDx9_3DDevice::ProcessVertices(), TDx9_3DDevice::DrawPrimitive(), etc) a clip code is calculated for each vertex using the ClipUnion and ClipIntersection settings. Vertices outside a particular clipping plane will have the corresponding bit set in its clip code. ClipUnion is a bitwise OR of all clip codes and ClipIntersection is a bitwise AND of all clipping codes. The initial values of ClipUnion and ClipIntersection are 0 and 0xFFFFFFFF respectively but both are set to 0 if clipping is not enabled. The clip status is updated during drawing calls but not by calls to TDx9_3DDevice::DrawRectPatch() or TDx9_3DDevice::DrawTriPatch() as there is no software emulation for those methods.
