DESCRIPTION

       This  node represents a 3D shape formed by constructing polylines from vertices located at
       the coordinates specified in the vertexProperty field (from SoVertexShape), or the current
       inherited coordinates. For optimal performance, the vertexProperty field is recommended.

       SoIndexedLineSet uses the indices in the coordIndex field (from SoIndexedShape) to specify
       the polylines. An index of SO_END_LINE_INDEX (-1) indicates that the current polyline  has
       ended and the next one begins.

       The  coordinates of the line set are transformed by the current cumulative transformation.
       The lines are drawn with the current light model and drawing style (drawing  style  FILLED
       is treated as LINES).

       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 (see SoIndexedShape). The default material binding is
       OVERALL. The default normal binding is PER_VERTEX_INDEXED

       The current complexity value has no effect on the rendering of indexed line sets.

METHODS

                         SoIndexedLineSet()
          Creates an indexed line set node with default settings.

     static SoType       getClassTypeId()
          Returns type identifier for this class.

ACTION BEHAVIOR

       SoGLRenderAction
          Draws lines based on the current coordinates, normals, materials, drawing style, and so
          on.

     SoRayPickAction
          Picks  lines  based  on  the  current coordinates and transformation. Details about the
          intersection are returned in an SoLineDetail.

     SoGetBoundingBoxAction
          Computes the bounding box that encloses all vertices of the line set with  the  current
          transformation  applied  to  them. Sets the center to the average of the coordinates of
          all vertices.

     SoCallbackAction
          If any line segment callbacks are registered with the action, they will be invoked  for
          each successive segment in the line set.
