Detailed Description

Polyline shape node.

This node represents a 3D shape formed by constructing a set of 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.

Coordinates are used in order, starting with startIndex (zero by default).

If the numVertices field contains -1 (the default), then all the coordinates (starting with startIndex) are rendered as a single polyline.

Otherwise each polyline uses the number of vertices specified by a value in the numVertices field. For example, an SoLineSet with a numVertices of [3,4,2] would use the first three coordinates for the first polyline, the next four coordinates for the second polyline, and the next two coordinates for the third polyline. Thus 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 line width and pattern are controlled by fields in SoDrawStyle.

The lines are drawn with the current drawing style (see SoDrawStyle), but drawing style FILLED is treated as LINES.

Treatment of the current material, normal and tangent binding is as follows:

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

Shape Antialiasing type is SoShape::LINES.
