A node that contains a plane. This is most often used as a clipping plane, but it can serve other purposes as well; whenever a plane is needed to be defined in some coordinate space in the world.
Returns the clip_effect bits for this clip plane. See
Returns the priority associated with this clip plane. See
Returns the size of the visual representation of the plane that is drawn if the
Specifies the sort of things this plane will actually clip (when it is used as a clip plane). This is a bitmask union of
ClipEffectvalues. If it includes CE_visible, then it will clip visible geometry; if it includes CE_collision, then it will clip collision polygons. If it includes neither bit, it will still affect culling, but objects will either be wholly behind the clipping plane, or wholly present.
Changes the relative importance of this
PlaneNode(when it is used as a clip plane) relative to the other clip planes that are applied simultaneously.
The priority number is used to decide which of the requested clip planes are to be activated when more clip planes are requested than the hardware will support. The highest-priority n planes are selected for rendering.
This is similar to
