class  Vrml_IndexedLineSet
 defines a IndexedLineSet node of VRML specifying geometry shapes.
This node represents a 3D shape formed by constructing polylines from vertices
located at the current coordinates. IndexedLineSet uses the indices in its coordIndex
field to specify the polylines. An index of -1 separates one polyline from the next
(thus, a final -1 is optional). the current polyline has ended and the next one begins.
Treatment of the current material and normal binding is as follows: The PER_PART binding
specifies a material or normal for each segment of the line. The PER_FACE binding
specifies a material or normal for each polyline. PER_VERTEX specifies a material or
normal for each vertex. The corresponding _INDEXED bindings are the same, but use
the materialIndex or normalIndex indices. The DEFAULT material binding is equal
to OVERALL. The DEFAULT normal binding is equal to PER_VERTEX_INDEXED;
if insufficient normals exist in the state, the lines will be drawn unlit. The same
rules for texture coordinate generation as IndexedFaceSet are used.
