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.

MFVec2f controlPoint
SFInt32 tessellation
MFFloat weight
Fields
A property or attribute of a node. Each node type has a fixed set of fields. Fields may contain various kinds of data and one or many values. Each field has a default value.

SFInt32 order
Events In
EventIn< MFVec2f > set_controlPoint
EventIn< SFInt32 > set_tessellation

Detailed Description

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

6.45 NurbsCurve2D

The NurbsCurve2D node defines a trimming segment that is part of a trimming contour in the u, v domain of the surface. The control points are all defined as 2D vertices in u, v domain. NurbsCurve2D are used as children to the Contour2D group.

In other respects, the NurbsCurve2D has the same functionality as defined for the NurbsCurve node.

Constructor & Destructor Documentation

NurbsCurve2D (  const char *  name = ""  ) 
 

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

  tessellation = 0;
  order = 3;

~NurbsCurve2D (   )  [virtual]
 

Virtual destructor, does nothing

Member Function Documentation

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

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.

wrl::Node::EventInHandle eventIn (  const 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.

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:

  • set_controlPoint
  • set_tessellation
  • set_weight

Implements Node.

wrl::Node::EventOutHandle eventOut (  const 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:

  • 0 : controlPoint_changed
  • 1 : tessellation_changed
  • 2 : weight_changed This function is useful, with nbEventsOut() if you want to traverse all events in of a Node.

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:

  • controlPoint_changed
  • tessellation_changed
  • weight_changed

Implements Node.

wrl::Node::FieldHandle field (  const 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:

  • 0 : controlPoint
  • 1 : tessellation
  • 2 : weight
  • 3 : knot
  • 4 : order This function is useful, with nbFields() if you want to traverse all fields of a Node.

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:

  • controlPoint
  • tessellation
  • weight
  • knot
  • order

Implements Node.

bool isSetToDefaultValue (  const 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.

unsigned int nbEventsOut (   )  const [inline, virtual]
 

Returns the number of events out for this node type.

Implements Node.

unsigned int nbFields (   )  const [inline, virtual]
 

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

Implements Node.

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

Returns "NurbsCurve2D". Useful for printing.

Implements Node.
