Detailed Description

Indexed point set shape node.

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.

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 SoVertexProperty or 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.

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 SoDrawStyle field pointSize.

Automatic simplification (by skipping points) is controlled by the 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 SoShape::POINTS.

Limitations:

The OpenGL VBO (vertex buffer object) rendering model only allows one set of indices for a primitive. Therefore it is not possible to use VBO rendering (and performance may be lower) if indices are set in the materialIndex, normalIndex or textureCoordIndex fields.

ACTION BEHAVIOR

SoGLRenderAction

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 vertices of the point 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 successive point in the set.
