| startIndex | Index of first coordinate of shape. |

(Inherited from SoFieldContainer.) |
| vertexProperty | vertex property node. |
RemarksThis node represents a set of points located at the coordinates specified by the vertexProperty field (from OIV.Inventor.Nodes.SoVertexShape) or the current inherited coordinates. For optimal performance, the vertexProperty field is recommended.
OIV.Inventor.Nodes.SoPointSet uses the coordinates in order, starting with the coordinate at startIndex. The number of coordinates to use (the number of points in the set) is specified by the OIV.Inventor.Nodes.SoPointSet.numPoints field. The default value of this field is -1, which means to use all the coordinates, so it may not be necessary to explicitly set this field.
The coordinates of the point set are transformed by the current cumulative transformation.
Lighting is not applied to points (i.e., they are rendered with light model BASE_COLOR) unless the application explicitly sets normal vectors using OIV.Inventor.Nodes.SoVertexProperty or OIV.Inventor.Nodes.SoNormal. Note that this is specific to direct rendering of point sets. If you render polygonal geometry, e.g. OIV.Inventor.Nodes.SoFaceSet, in POINTS mode (OIV.Inventor.Nodes.SoDrawStyle), normal vectors are computed by Open Inventor and lighting is enabled.
NOTE: If you want to apply lighting in a shader, you still need to explicitly set normal vectors, otherwise lighting will be disabled for the point set.
Point size is controlled by the OIV.Inventor.Nodes.SoDrawStyle field pointSize.
Automatic simplification (by skipping points) is controlled by the OIV.Inventor.Nodes.SoComplexity field value. Only values < 0.5 have any effect.
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.
Shape Antialiasing type is OIV.Inventor.Nodes.SoShape.ShapeTypes.POINTS.
Limitations:
By default, OIV.Inventor.Nodes.SoPointSet ignores the vertex ordering set on the state by OIV.Inventor.Nodes.SoShapeHints nodes in order to avoid a performance hit on some GeForce cards. However, this default behavior can be changed using the environment variable OIV_POINT_SET_USE_VERTEX_ORDERING (see OIV.Inventor.SoPreferences).

ACTION BEHAVIOR
OIV.Inventor.Actions.SoGLRenderAction Draws points based on the current coordinates, normals, materials, drawing style, and so on.
OIV.Inventor.Actions.SoRayPickAction Picks points based on the current coordinates and transformation. Details about the intersection are returned in an OIV.Inventor.Details.SoPointDetail.
OIV.Inventor.Actions.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.
OIV.Inventor.Actions.SoCallbackAction If any point callbacks are registered with the action, they will be invoked for each point in the set.
