public class SoPointSet extends SoNonIndexedShape
SoVertexShape) or the current inherited coordinates. For optimal performance, the
vertexPropertyfield is recommended.
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
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 point sets (i.e., they are rendered with light model BASE_COLOR) unless the application explicitly sets normal vectors using
SoNormal. Note that this is specific to direct rendering of point sets. If you render polygonal geometry, e.g.
SoFaceSet, in POINTS mode (
SoDrawStyle), normal vectors are computed by Open Inventor and lighting is enabled.
Point size is controlled by the
Automatic simplification (by skipping points) is controlled by the
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.
By default OpenGL renders points as "squares". To get round points (points rendered as circles) you must explicitly enable
point smoothing, using the setSmoothing() method in the
SoGLRenderAction class. You can get the current render action object from the viewer (or from the
SoSceneManager if you are not using a viewer).
Shape Antialiasing type is
Draws points based on the current coordinates, normals, materials, drawing style, and so on.
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.
