Detailed Description

The SoVRMLInterpolator class is an internal abstract class.

This class collects the two fields that are common for all interpolator nodes, plus common code that operates on these fields. Since this is an abstract "helper" class, it does not represent an actual node from the VRML97 specification, so don't use it as such.

For more information, a detailed discussion of interpolators is available in section 4.6.8 of the VRML97 specification:

http://www.web3d.org/x3d/specifications/vrml/ISO-IEC-14772-VRML97/part1/concepts.html#4.6.8

Member Function Documentation

◆ getTypeId()

SoType SoVRMLInterpolator::getTypeId ( void ) const

virtual

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:

void foo(SoNode * node)
{
  if (node->getTypeId() == SoFile::getClassTypeId()) {
    SoFile * filenode = (SoFile *)node;  // safe downward cast, knows the type
  }
}

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.

Implements SoBase.

Reimplemented in SoVRMLPositionInterpolator, SoVRMLColorInterpolator, SoVRMLOrientationInterpolator, SoVRMLCoordinateInterpolator, SoVRMLNormalInterpolator, and SoVRMLScalarInterpolator.

◆ getFieldData()

const SoFieldData * SoVRMLInterpolator::getFieldData ( void ) const

protectedvirtual

Returns a pointer to the class-wide field data storage object for this instance. If no fields are present, returns NULL.

Reimplemented from SoFieldContainer.

Reimplemented in SoVRMLPositionInterpolator, SoVRMLColorInterpolator, SoVRMLOrientationInterpolator, SoVRMLCoordinateInterpolator, SoVRMLNormalInterpolator, and SoVRMLScalarInterpolator.

◆ getOutputData()

const SoEngineOutputData * SoVRMLInterpolator::getOutputData ( void ) const

virtual

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.

Implements SoNodeEngine.

Reimplemented in SoVRMLPositionInterpolator, SoVRMLColorInterpolator, SoVRMLOrientationInterpolator, SoVRMLCoordinateInterpolator, SoVRMLNormalInterpolator, and SoVRMLScalarInterpolator.

◆ getKeyValueIndex()

int SoVRMLInterpolator::getKeyValueIndex	(	float &	interp,
		int	numvalues
	)

protected

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.

Member Data Documentation

◆ key

SoMFFloat SoVRMLInterpolator::key

This field contains a set of floating point values which the interpolation will run over. The key values should be monotonically non-decreasing.

The field is inherited from it's declaration in the abstract SoVRMLInterpolator class into a range of different VRML interpolator nodes.

See the class documentation of the non-abstract VRML interpolator node you want to use for information on what the key values represent in that specific context.

◆ set_fraction

SoSFFloat SoVRMLInterpolator::set_fraction

The set_fraction field gets an input signal that triggers a calculation of the next value_changed eventOut value.

The field is inherited from it's declaration in the abstract SoVRMLInterpolator class into a range of different VRML interpolator nodes.

The documentation for this class was generated from the following files:

SoVRMLInterpolator.h
Interpolator.cpp
