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.
FUNCTIONSSoPointSet * SoPtSetCreate()
Creates a point set node with default settings.
SoType SoPtSetGetClassTypeId()
Returns type identifier for this class.
Page 2SoPointSet(3IV)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.
