The IndexedLineSet node represents a 3D geometry formed by constructing polylines from 3D points specified in the coord field. IndexedLineSet uses the indices in its coordIndex field to specify the polylines by connecting together points from the coord field. An index of -1 indicates that the current polyline has ended and the next one begins. The last polyline may (but does not have to be) followed by a -1. IndexedLineSet is specified in the local coordinate system and is affected by parent transformations.

The coord field specifies the 3D vertices of the line set and is specified by a Coordinate node.

Lines are not lit, not texture-mapped, or not collided with during collision detection.

If the color field is not NULL, it must contain a Color node, and the colors are applied to the line(s) as follows:

• If colorPerVertex is FALSE:
  • If the colorIndex field is not empty, then one color is used for each polyline of the IndexedLineSet. There must be at least as many indices in the colorIndex field as there are polylines in the IndexedLineSet. If the greatest index in the colorIndex field is N, then there must be N+1 colors in the Color node. The colorIndex field must not contain any negative entries.
  • If the colorIndex field is empty, then the colors are applied to each polyline of the IndexedLineSet in order. There must be at least as many colors in the Color node as there are polylines.
• If colorPerVertex is TRUE:
  • If the colorIndex field is not empty, then colors are applied to each vertex of the IndexedLineSet in exactly the same manner that the coordIndex field is used to supply coordinates for each vertex from the Coordinate node. The colorIndex field must contain at least as many indices as the coordIndex field and must contain end-of-polyline markers (-1) in exactly the same places as the coordIndex field. If the greatest index in the colorIndex field is N, then there must be N+1 colors in the Color node.
  • If the colorIndex field is empty, then the coordIndex field is used to choose colors from the Color node. If the greatest index in the coordIndex field is N, then there must be N+1 colors in the Color node.

If the color field is NULL and there is a Material defined for the Appearance affecting this IndexedLineSet, then use the emissiveColor of the Material to draw the lines. See "Concepts - Lighting Model, Lighting Off" for details on lighting equations.
