ClipPlane specifies a single plane equation used to clip (i.e. cull or hide) displayed geometry. The plane field specifies a four-component plane equation that describes both inside and outside half space.
The ClipPlane node belongs to the Rendering component and its container field is children. It is available since X3D version 3.2 or later.
SFNode [in, out] metadata NULL [X3DMetadataObject]
Metadata are not part of the X3D world and not interpreted by the X3D browser, but they can be accessed via the ECMAScript interface.
SFBool [in, out] enabled TRUE
Enables/disables node operation.
SFVec4f [in, out] plane 0 1 0 0 [0,1]
If (a,b,c,d) is the plane, with the first three components being a normalized vector describing the plane's normal direction (and thus the fourth component d being distance from the origin), a point (x,y,z) is visible to the user, with regards to the clipping plane, if a*x+b*y+c*z+d is greater than 0.
Negate all plane values to reverse which side of plane has visibility clipped.
(a, b, c) value of (0, 0, 0) is forbidden since the zero vector has ambiguous direction and is thus degenerate, not defining a plane.
