ZGroup

The ZGroup node enables/disables writing children geometry in Z-buffer and checking Z-buffer during its output.

EXTERNPROTO ZGroup [ eventIn MFNode addChildren eventIn MFNode removeChildren exposedField MFNode children [] field SFVec3f bboxCenter 0 0 0 # (-inf inf) field SFVec3f bboxSize -1 -1 -1 # (0, inf) or -1,-1,-1 exposedField SFBool write TRUE exposedField SFBool check TRUE exposedField SFBool writePixelBuffer TRUE ] [ "urn:inet:parallelgraphics.com:cortona:ZGroup" "http://www.parallelgraphics.com/vrml/proto/Cortona/extensions.wrl#ZGroup" ]

The fields of the ZGroup node, with the exception of the check, and write fields, are analogous to the corresponding fields of the Group VRML node.

Fields and events

check  Specifies whether Z-buffer is checked during rendering of geometry specified in the children field.

write  Specifies whether the children geometry should be written to Z-buffer.

writePixelBuffer  Specifies whether the children geometry should be written to pixel-buffer. The default value of writePixelBuffer is TRUE.
