class IndexedLineSet from Vrml inherits TShared from MMgt
---Purpose: 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.
