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.

SoLineSet uses the coordinates in order, starting with the first one. Each line has a number of vertices specified by a value in the numVertices field. For example, an SoLineSet with a numVertices 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.

The number of values in the numVertices field indicates the number of polylines in the set.

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. The _INDEXED bindings are equivalent to their non-indexed counterparts. The default material binding is OVERALL. The default normal binding is PER_VERTEX.

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


SoMFInt32 numVertices
Number of vertices per polyline.


Creates a line set node with default settings.

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

Action Behavior

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

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

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.

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