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.

6.49 NurbsTextureSurface

The NurbsTextureSurface node is a NURBS surface existing in the parametric domain of its surface host specifying the mapping of the texture onto the surface. 

The parameters are as specified for the NurbsSurface node with the exception that the control points are specified in (u, v) coordinates.

The tessellation process generates 2D texture coordinates. If the NurbsTextureSurface is undefined, texture coordinates are computed by the client on the basis of parametric step size. Conventional vertex parameters do not apply on NURBS because triangles are only available after polygonization, but the conventional texture transform may be used.

NurbsTextureSurface nodes are accessed through the texCoord field of the NurbsSurface node. A NurbsTextureSurface node separately encountered is ignored.

Constructor & Destructor Documentation

NurbsTextureSurface (  const char *  name = ""  ) 
 

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

  uDimension = 0;
  uOrder = 3;
  vDimension = 0;
  vOrder = 3;

~NurbsTextureSurface (   )  [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_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 : 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
  • 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 : weight
  • 2 : uDimension
  • 3 : uKnot
  • 4 : uOrder
  • 5 : vDimension
  • 6 : vKnot
  • 7 : vOrder 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
  • weight
  • uDimension
  • uKnot
  • uOrder
  • vDimension
  • vKnot
  • vOrder

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 "NurbsTextureSurface". Useful for printing.

Implements Node.
