IndexedLineSet {
SFNode coord NULL # {Coordinate, PROTO}
MFInt32 coordIndex [ ] # [-1, inf)
}
The IndexedLineSet node represents a 3D geometry formed by constructing polylines from 3D vertices specified in the coord field.
IndexedLineSet uses the indices in its coordIndex field to specify the polylines by connecting vertices from the coord field.
An index of "-1" indicates that the current polyline has ended and the next one begins.
The last polyline may be (but does not have to be) followed by a "-1".
IndexedLineSet is specified in the local coordinate system and is affected by the transformations of its ancestors.
The coord field contains a Coordinate node that specifies the 3D vertices of the line set.
IndexedLineSet nodes don't support PBRAppearance. You may however set an Appearance node in the Shape containing the IndexedLineSet geometry. IndexedLineSet nodes are not lit, not texture-mapped and they do not cast or receive shadows. IndexedLineSet nodes cannot be used for collision detection (boundingObject).
