0031 //! defines a IndexedLineSet node of VRML specifying geometry shapes.
0032 //! This node represents a 3D shape formed by constructing polylines from vertices
0033 //! located at the current coordinates. IndexedLineSet uses the indices in its coordIndex
0034 //! field to specify the polylines. An index of -1 separates one polyline from the next
0035 //! (thus, a final -1 is optional). the current polyline has ended and the next one begins.
0036 //! Treatment of the current material and normal binding is as follows: The PER_PART binding
0037 //! specifies a material or normal for each segment of the line. The PER_FACE binding
0038 //! specifies a material or normal for each polyline. PER_VERTEX specifies a material or
0039 //! normal for each vertex. The corresponding _INDEXED bindings are the same, but use
0040 //! the materialIndex or normalIndex indices. The DEFAULT material binding is equal
0041 //! to OVERALL. The DEFAULT normal binding is equal to  PER_VERTEX_INDEXED;
0042 //! if insufficient normals exist in the state, the lines will be drawn unlit. The same
0043 //! rules for texture coordinate generation as IndexedFaceSet are used.
