DESCRIPTION

69       This node represents a 3D shape formed by constructing  polylines  from
70       vertices  located  at  the  coordinates specified in the vertexProperty
71       field (from SoVertexShape), or the current inherited  coordinates.  For
72       optimal performance, the vertexProperty field is recommended.
73
74       SoIndexedLineSet  uses  the indices in the coordIndex field (from SoIn‐
75       dexedShape) to specify the polylines.  An  index  of  SO_END_LINE_INDEX
76       (-1)  indicates  that  the  current polyline has ended and the next one
77       begins.
78
79       The coordinates of the line set are transformed by the current  cumula‐
80       tive  transformation.  The lines are drawn with the current light model
81       and drawing style (drawing style FILLED is treated as LINES).
82
83       Treatment of the current material and normal binding is as follows: The
84       PER_PART binding specifies a material or normal for each segment of the
85       line. The PER_FACE binding specifies a  material  or  normal  for  each
86       polyline.  PER_VERTEX  specifies  a material or normal for each vertex.
87       The corresponding _INDEXED bindings are the same, but use  the  materi‐
88       alIndex  or normalIndex indices (see SoIndexedShape). The default mate‐
89       rial binding  is  OVERALL.  The  default  normal  binding  is  PER_VER‐
90       TEX_INDEXED
91
92       The  current complexity value has no effect on the rendering of indexed
93       line sets.

METHODS

96                         SoIndexedLineSet()
97          Creates an indexed line set node with default settings.
98
99     static SoType       getClassTypeId()
100          Returns type identifier for this class.

ACTION BEHAVIOR

104       SoGLRenderAction
105          Draws lines based on the current  coordinates,  normals,  materials,
106          drawing style, and so on.
107
108     SoRayPickAction
109          Picks  lines  based  on  the current coordinates and transformation.
110          Details about the intersection are returned in an SoLineDetail.
111
112     SoGetBoundingBoxAction
113          Computes the bounding box that encloses all vertices of the line set
114          with  the current transformation applied to them. Sets the center to
115          the average of the coordinates of all vertices.
116
117     SoCallbackAction
118          If any line segment callbacks are registered with the  action,  they
119          will be invoked for each successive segment in the line set.
