## DESCRIPTION

**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**.

## FIELDS

**SoSFInt32**	**numPoints**\
 Number of points.

## METHODS

	**SoPointSet()**\
 Creates a point set node with default settings.

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

## ACTION BEHAVIOR

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

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

**SoGetBoundingBoxAction**\
 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.

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

## FILE FORMAT/DEFAULTS

```
PointSet {
vertexProperty	NULL
startIndex	0
numPoints	-1
}
```
