NurbsPositionInterpolator describes a 3D NURBS Curve using dimension, keyValue, keyWeight, knot, and order as described for the NurbsCurve node.
The fields set_fraction and value_changed have the same meaning as in the base VRML PositionInterpolator.
Sending a set_fraction input computes a 3D position on the curve, which is sent by value_changed. The set_fraction value is used as the input value for the tessellation function. Thereby, the knot corresponds to the key field of a conventional interpolator node; i.e., if the set_fraction value is within [0;1] and the knot vector within [0;2], only half of the curve is computed.

Virtual destructor, does nothing
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. Here is how i
is related to fields:
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 "NurbsPositionInterpolator"
. 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.
