This node represents a set of points located at the coordinates specified by the vertexProperty field (from SoVertexShape) or the current inherited coordinates. For optimal performance, the vertexProperty field is recommended.

SoPointSet uses the coordinates in order, starting with the first one. The number of points in the set is specified by the numPoints field.

The coordinates of the point set are transformed by the current cumulative transformation. The points are drawn with the current light model and drawing style (drawing styles FILLED and LINES are treated as POINTS).

Treatment of the current material and normal binding is as follows: PER_PART, PER_FACE, and PER_VERTEX bindings bind one material or normal to each point. The default material binding is OVERALL. The default normal binding is PER_VERTEX.


SoSFInt32 numPoints

Number of points.



Creates a point set node with default settings.

static SoType getClassTypeId()

Returns type identifier for this class.



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


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


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


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