NAME SoLineSet SoLSet "" { polyline shape node }
INCLUDE nodes/SoLineSet.h
DESC {
This node represents a 3D shape formed by constructing polylines from
vertices located at the coordinates specified in the
\vvertexProperty\. field (from \cSoVertexShape\.),
or the current inherited coordinates.
For optimal performance, the \vvertexProperty\. field is recommended.
\p
\cSoLineSet\. uses the
coordinates in order, starting with the first one.
Each line has a number of vertices specified by
a value in the \vnumVertices\. field. For example, an \cSoLineSet\.
with a \vnumVertices\. of [3,4,2] would use
coordinates 1, 2, and 3 for the first line, coordinates 4, 5, 6, and 7
for the second line, and coordinates 8 and 9 for the third. \p
The number of values in the \vnumVertices\. field indicates the
number of polylines in the set.
\p
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 \kFILLED\. is treated as
\kLINES\.).
\p
Treatment of the current material and normal binding is as follows:
The \kPER_PART\. binding specifies a material or normal for each
segment of the line. The \kPER_FACE\. binding specifies a material or
normal for each polyline. The \k_INDEXED\. bindings are equivalent to
their non-indexed counterparts. The default material binding is
\kOVERALL\.. The default normal binding is
\kPER_VERTEX\..
\p
The current complexity value has no effect on the rendering of line
sets.

FIELD numVertices { Number of vertices per polyline. }
METHOD "" SoLineSet() { Creates a line set node with default settings. }
METHOD "" static SoType getClassTypeId() {
Returns type identifier for this class.
}
ACTION SoGLRenderAction {
Draws lines based on the current coordinates, normals, materials,
drawing style, and so on.
}
ACTION SoRayPickAction {
Picks lines based on the current coordinates and transformation.
Details about the intersection are returned in an \cSoLineDetail\..
}
ACTION 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.
}
ACTION SoCallbackAction {
If any line segment callbacks are registered with the action, they will
be invoked for each successive segment in the line set.
