SoTextureCubeMap(3) on Linux
The text be2e54b54c86, as Debian 6.0 (Squeeze) shipped it.
The SoTextureCubeMap class is used to map a cube map onto subsequent shape nodes. Shape nodes within the scope of SoTextureCubeMap nodes in the scenegraph (ie below the same SoSeparator and to the righthand side of the SoTextureCubeMap) will have the texture applied according to each shape type's individual characteristics. See the documentation of the various shape types (SoFaceSet, SoCube, SoSphere, etc etc) for information about the specifics of how the textures will be applied.
