Public Attributes

Exposed Fields
A field that is capable of receiving events via an eventIn to change its value(s), and generating events via an eventOut when its value(s) change.

Detailed Description

Here is the documentation for this node type, from the ISO standard.

+6.54 PointSet

The PointSet node specifies a set of 3D points, in the local coordinate system, with associated colours at each point. The coord field specifies a Coordinate or GeoCoordinate node (or instance of such a node). The results are undefined if the coord field specifies any other type of node. PointSet uses the coordinates in order. If the coord field is NULL, the point set is considered empty.

PointSet nodes are not lit, not texture-mapped, nor do they participate in collision detection. The size of each point is implementation-dependent.

If the color field is not NULL, it shall specify a Color node that contains at least the number of points contained in the coord node. The results are undefined if the color field specifies any other type of node. Colours shall be applied to each point in order. The results are undefined if the number of values in the Color node is less than the number of values specified in the Coordinate or GeoCoordinate node.

If the color field is NULL and there is a Material node defined for the Appearance node affecting this PointSet node, the emissiveColor of the Material node shall be used to draw the points. More details on lighting equations can be found in 4.14, Lighting model.


Constructor & Destructor Documentation

PointSet ( const char *  name = ""  ) 

Construct a node with all its fields set to default value, which is equivalent to the code below:

~PointSet (  )  [virtual]

Virtual destructor, does nothing


Member Function Documentation

unsigned int nbFields (  )  const [inline, virtual]

Returns the number of fields (exposed or not) for this node type.

Implements Node.

wrl::Node::FieldHandle field ( const std::string &  n  )  [virtual]

Return a handle on the field named n of the node or a "unknown" typed handle if there is no such field. Valid names are:

Implements Node.

wrl::Node::FieldHandle field ( unsigned int  n  )  [virtual]

Return a handle on the i th field of the node or a "unknown" typed handle if there is no such node. Here is how i is related to fields:

Implements Node.

bool isSetToDefaultValue ( unsigned int  i  )  const [virtual]

Implements Node.

unsigned int nbEventsIn (  )  const [inline, virtual]

Returns the number of events in for this node type.

Implements Node.

wrl::Node::EventInHandle eventIn ( const std::string &  n  )  [virtual]

Return a handle on the event in named n of the node or a "unknown" typed handle if there is no such event. Valid names are:

Implements Node.

wrl::Node::EventInHandle eventIn ( unsigned int  n  )  [virtual]

Return a handle on the i th event in of the node or a "unknown" typed handle if there is no such node. emarks This class has no eventIn. This function is useful, with nbEventsIn() if you want to traverse all events in of a Node.

Implements Node.

unsigned int nbEventsOut (  )  const [inline, virtual]

Returns the number of events out for this node type.

Implements Node.

wrl::Node::EventOutHandle eventOut ( const std::string &  n  )  [virtual]

Return a handle on the event out named n of the node or a "unknown" typed handle if there is no such event. Valid names are:

Implements Node.

wrl::Node::EventOutHandle eventOut ( unsigned int  n  )  [virtual]

Return a handle on the i th event out of the node or a "unknown" typed handle if there is no such node. Here is how i is related to fields:

Implements Node.

const char * typeName (  )  const [inline, virtual]

Returns "PointSet". Useful for printing.

Implements Node.

wrl::Node * duplicate (  )  const [virtual]

Returns a deep copy of this node, that is a fully independant node with all children (if any) also copied. This is mainly useful for instanciating protos.

Implements Node.

virtual Node* duplicate ( std::map< const Node *, Node * > &   )  const [virtual]

Implements Node.
