Inheritance diagram for SoVRMLScalarInterpolator:
ScalarInterpolator { eventIn SFFloat set_fraction # (-inf, inf) exposedField MFFloat key [] # (-inf, inf) exposedField MFFloat keyValue [] # (-inf, inf) eventOut SFFloat value_changed }
This node linearly interpolates among a list of SFFloat values. This interpolator is appropriate for any parameter defined using a single floating point value. Examples include width, radius, and intensity fields. The keyValue field shall contain exactly as many numbers as there are keyframes in the key field. A more detailed discussion of interpolators is available in 4.6.8, Interpolator nodes (<http://www.web3d.org/technicalinfo/specifications/vrml97/part1/concepts.html#4.6.8>).

Constructor. |
|
Destructor. |
|
This static method returns the SoType object associated with objects of this class. Reimplemented from SoVRMLInterpolator. |
|
Returns the type identification of an object derived from a class inheriting SoBase. This is used for run-time type checking and "downward" casting. Usage example:
For application programmers wanting to extend the library with new nodes, engines, nodekits, draggers or others: this method needs to be overridden in all subclasses. This is typically done as part of setting up the full type system for extension classes, which is usually accomplished by using the pre-defined macros available through for instance Inventor/nodes/SoSubNode.h (SO_NODE_INIT_CLASS and SO_NODE_CONSTRUCTOR for node classes), Inventor/engines/SoSubEngine.h (for engine classes) and so on. For more information on writing Coin extensions, see the class documentation of the toplevel superclasses for the various class groups. Reimplemented from SoVRMLInterpolator. |
|
Returns the SoFieldData class which holds information about inputs in this engine. Reimplemented from SoVRMLInterpolator. |
|
Returns a pointer to the class-wide field data storage object for this instance. If no fields are present, returns Reimplemented from SoVRMLInterpolator. |
|
Returns the SoEngineOutputData class which holds information about the outputs in this engine. Reimplemented from SoVRMLInterpolator. |
|
This API member is considered internal to the library, as it is not likely to be of interest to the application programmer. Reimplemented from SoVRMLInterpolator. |
|
Sets up initialization for data common to all instances of this class, like submitting necessary information to the Coin type system. Reimplemented from SoVRMLInterpolator. |
|
The keyValue vector. |
|
The eventOut which is sent every time the interpolator has calculated a new value. |
