Detailed Description

The SoPointCloud class is used to display a set of 3D points.

When a point is closer to the camera than a specified distance, it will be rendered as a cube/sphere/diamond (specified by the 'shape' field).

This node either uses the coordinates currently on the state (typically set up by a leading SoCoordinate3 node in the scene graph) or from a SoVertexProperty node attached to this node to render a set of 3D points.

The SoPointCloud::numPoints field specifies the number of points in the coordinate set which should be rendered (or otherwise handled by traversal actions).

Member Data Documentation

numPoints

SoSFInt32 SoPointCloud::numPoints

Used to specify number of points in the point cloud. Coordinates for the points will be taken from the state stack's set of 3D coordinates, typically set up by a leading SoCoordinate3 node.

If this field is equal to -1 (the default value) all coordinates currently on the state will be rendered or otherwise handled by traversal actions.

SoPointCloud inherits the field SoNonIndexedShape::startIndex, which specifies the start index for points from the current state set of coordinates. Please note that this field has been obsoleted, but is still provided for compatibility.
