public class SoIndexedPointSet extends SoIndexedShape
SoVertexShape) or the current inherited coordinates. For optimal performance, the
vertexPropertyfield is recommended.
Each point consists of one vertex, which is denoted by an integer index (from the
coordIndex field) into the current coordinates. The number of values in the coordIndex field defines the number of points. Depending on the current material and normal binding values, the materials and normals for the vertices may be accessed in order or indexed. If they are indexed, the materialIndex and normalIndex fields are used.
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
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 vertices of the point 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 successive point in the set.
