The planes are specified in the local coordinate system of this node, and may be individually enabled or disabled. This node also specifies a region of influence in which this set of planes is active.<p> A ModelClip node also contains a list of Group nodes that specifies the hierarchical scope of this ModelClip. If the scope list is empty, then the ModelClip node has universe scope: all nodes within the region of influence are affected by this ModelClip node. If the scope list is non-empty, then only those Leaf nodes under the Group nodes in the scope list are affected by this ModelClip node (subject to the influencing bounds). <p> If the regions of influence of multiple ModelClip nodes overlap, the Java 3D system will choose a single set of model clip planes for those objects that lie in the intersection. This is done in an implementation-dependent manner, but in general, the ModelClip node that is "closest" to the object is chosen. <p> The individual planes specify a half-space defined by the equation: <ul> Ax + By + Cz + D <= 0 </ul> where A, B, C, D are the parameters that specify the plane. The parameters are passed in the x, y, z, and w fields, respectively, of a Vector4d object. The intersection of the set of half-spaces corresponding to the enabled planes in this ModelClip node defines a region in which points are accepted. Points in this acceptance region will be rendered (subject to view clipping and other attributes). Points that are not in the acceptance region will not be rendered.<P><P><DL><DT><B>Since:</B><DD>Java 3D 1.2</DD></DD></DL><HR><P><!-- ======== NESTED CLASS SUMMARY ======== --><!-- =========== FIELD
