Detailed Description
This node defines a set of explicit fog depths on a per-vertex basis.
This depth value shall be applied per-vertex and used to replace the automatically generated depth. Fog coordinates take precedence over implicitly generated depths; specifying fog coordinates will result in the implicit depth (specified by the visibilityRange field of a node derived from X3DFogObject) being ignored.
One depth value per vertex shall be supplied. If the user does not provide a sufficient number of depth values, the last value defined shall be replicated for any further vertices. (not yet implemented in the vertex array and VBO rendering case) If too many depth values are supplied, the excess depth values shall be ignored.
Examples:
