NAME SoPointSet SoPtSet "" { point set shape node }
INCLUDE nodes/SoPointSet.h
DESC {
This node represents a set of points located at the
coordinates specified by the \vvertexProperty\. field (from \cSoVertexShape\.)
or the current inherited coordinates. For optimal performance,
the \vvertexProperty\. field is recommended.
\p
\cSoPointSet\. uses the coordinates in order,
starting with the first one. The
number of points in the set is specified by the \vnumPoints\. field.
\p
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 \kFILLED\. and \kLINES\. are
treated as \kPOINTS\.).
\p
Treatment of the current material and normal binding is as follows:
\kPER_PART\., \kPER_FACE\., and \kPER_VERTEX\. bindings bind one
material or normal to each point. The default material binding is
\kOVERALL\.. The default normal binding is
\kPER_VERTEX\..
}
FIELD numPoints { Number of points. }
METHOD "" SoPointSet() { Creates a point set node with default settings. }
METHOD "" static SoType getClassTypeId() {
Returns type identifier for this class.
}
ACTION SoGLRenderAction {
Draws points based on the current coordinates, normals, materials,
drawing style, and so on.
}
ACTION SoRayPickAction {
Picks points based on the current coordinates and transformation.
Details about the intersection are returned in an \cSoPointDetail\..
}
ACTION 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.
}
ACTION SoCallbackAction {
If any point callbacks are registered with the action, they will be
invoked for each point in the set.
