ClipStatusFlags Enumeration

Defines the current clip status.

This enumeration has a FlagsAttribute attribute that allows a bitwise combination of its member values.

Members

	Member name	Description
	All	Combination of all clip flags.
	Back	All vertices are clipped by the back plane of the viewing frustum.
	Bottom	All vertices are clipped by the bottom plane of the viewing frustum.
	Front	All vertices are clipped by the front plane of the viewing frustum.
	Left	All vertices are clipped by the left plane of the viewing frustum.
	Right	All vertices are clipped by the right plane of the viewing frustum.
	Top	All vertices are clipped by the top plane of the viewing frustum.

Remarks

When clipping is enabled during vertex processing (by ProcessVertices, DrawPrimitives, or other drawing functions), Direct3D computes a clip code for every vertex. The clip code is a combination of ClipStatusFlags. When a vertex is outside a particular clipping plane, the corresponding bit is set in the clip code. Direct3D maintains the clip status using ClipStatus, which has ClipIntersection and ClipUnion properties. ClipUnion is a bitwise OR of all vertex clip codes, and ClipIntersection is a bitwise AND of all vertex clip codes. Initial values are 0 for ClipUnion and 0xFFFFFFFF for ClipIntersection.

When the Clipping property is set to false, ClipUnion and ClipIntersection are set to 0. Direct3D updates the clip status during drawing calls. To compute clip status for a particular object, set ClipUnion and ClipIntersection to their initial values and continue drawing.
