The D3DDDIARG_SETCLIPPLANE structure describes a clip plane.
Index [in]The index of the clipping plane for which the plane equation coefficients are set.
Plane [in]A four-element array of the coefficients A, B, C, and D, in that order, in the general plane equation for the clipping plane.
The general plane equation in standard form is Ax + By + Cz + Dw = 0. A point with homogeneous coordinates (x, y, z, w) is visible in the half-space of this plane if Ax + By + Cz + Dw >= 0. Points that exist on or behind the clipping plane are clipped from the scene. That is, points for which Ax + By + Cz + Dw < 0 are clipped.
