Defines a homogeneous vertex used when the application is supplying screen coordinate data that needs clipping. This structure is part of the D3DTRANSFORMDATA structure.
Flags defining the clip status of the homogeneous vertex. This member can be one or more of the flags described in the dwClip member of the D3DTRANSFORMDATA structure.
Values of the D3DVALUE type describing transformed homogeneous coordinates. These coordinates define the vertex.
