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.

MFFloat key
MFVec3f keyValue
Events In
EventIn< SFFloatset_fraction
EventIn< MFFloatset_key
EventIn< MFVec3fset_keyValue
Events Out
EventOut< MFVec3fvalue_changed
EventOut< MFFloatkey_changed
EventOut< MFVec3fkeyValue_changed


Detailed Description

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

+6.15 CoordinateInterpolator

This node linearly interpolates among a list of MFVec3f values. The number of coordinates in the keyValue field shall be an integer multiple of the number of keyframes in the key field. That integer multiple defines how many coordinates will be contained in the value_changed events.

4.6.8, Interpolator nodes, contains a more detailed discussion of interpolators.

Constructor & Destructor Documentation

CoordinateInterpolator ( const char *  name = ""  ) 

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

~CoordinateInterpolator (  )  [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. 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 "CoordinateInterpolator". 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.
