   Classes
       class SoBoolOperation
           The SoBoolOperation engine evaluates expressions of boolean logic.

       The multivalue fields SoBoolOperation::a and SoBoolOperation::b are combined according to
       the operations set in SoBoolOperation::operation, with the resulting TRUE or FALSE value
       set on SoBoolOperation::output. "
   class SoCalculator
       General purpose calculator for floats and 3D float vectors.

       The SoCalculator uses the values from the input fields (which are either single floating
       point values or vectors) as variables in the free-form engine expressions and places the
       results on the output fields. "
   class SoComposeMatrix
       The SoComposeMatrix class is used to compose a matrix from miscellaneous transformations.
   class SoComposeRotation
       The SoComposeRotation class is used to compose rotations from angle and axis.

       Simple usage example: "
   class SoComposeRotationFromTo
       The SoComposeRotationFromTo class is used to compose rotations based on from and to
       vectors.

   class SoComputeBoundingBox
       The SoComputeBoundingBox class is used to calculate a bounding box.

       This engine is simply a wrapper around the SoGetBoundingBoxAction, for a convenient way of
       having automatic updating of some data in the scene graph which is dependent on the
       bounding box of some other part of the scene. "
   class SoConcatenate
       The SoConcatenate class is used to concatenate several inputs into one output.

       Takes all the values from the 10 input multivalue fields in turn and concatenates them
       into the multivalue output. "
   class SoCounter
       The SoCounter class is an integer counter engine.

       The engine counts from its min value to its max value, adding the value of step each time
       trigger is touched. "
   class SoDecomposeMatrix
       The SoDecomposeMatrix class is used to decompose a matrix into simple transformations.
   class SoDecomposeRotation
       The SoDecomposeRotation class is used to decompose a rotation into angle and axis.
   class SoDecomposeVec2f
       The SoDecomposeVec2f class is used to decompose 2D vectors into two floats.
   class SoDecomposeVec3f
       The SoDecomposeVec3f class is used to decompose 3D vectors into three floats.
   class SoDecomposeVec4f
       The SoDecomposeVec4f class is used to decompose 4D vectors into four floats.
   class SoElapsedTime
       The SoElapsedTime class is a controllable time source engine.

       The additional functionality provided by this engine versus just connecting to the
       realTime global field is the ability to control the speed of the time source plus logic to
       reset, stop and restart it. "
   class SoEngine
       SoEngine is the base class for Coin engines.

       Engines enables the application programmers to make complex connections between fields. "
   class SoEngineOutput
       The SoEngineOutput class is the output slots in SoEngine instances.

       SoEngineOutput has methods for convenient handling of the connections made from SoEngine
       objects to SoField objects. "
   class SoFieldConverter
       The SoFieldConverter class is the abstract base class for field converters.

       When fields of different types are attempted connected, the Coin library tries to find a
       field converter class which can be inserted between them, acting as a filter converting
       values from the master field to values matching the type of the slave field. "
   class SoGate
       The SoGate class is used to selectively copy values from input to output.

       This engine will forward values from the SoGate::input field to the SoGate::output field
       when the SoGate::enable field is TRUE. "
   class SoHeightMapToNormalMap
       Engine for computing a normal map from a height map.
   class SoInterpolate
       The SoInterpolate class is the base class for all interpolator engines.

       Interpolators are used to linearly interpolate between two values. "
   class SoInterpolateFloat
       The SoInterpolateFloat class is used to interpolate two floating point values.
   class SoInterpolateRotation
       The SoInterpolateRotation class is used to interpolate between two rotations.
   class SoInterpolateVec2f
       The SoInterpolateVec2f class is used to interpolate between pairs of 2D vectors.
   class SoInterpolateVec3f
       The SoInterpolateVec3f class is used to interpolate between pairs of 3D vectors.
   class SoInterpolateVec4f
       The SoInterpolateVec4f class is used to interpolate between pairs of 4D vectors.
   class SoNodeEngine
       SoNodeEngine is the base class for Coin node engines.

       Node engines have the same functionality as normal engines, except that they inherit
       SoNode, which makes it possible to insert node engines in the scene graph. "
   class SoOneShot
       The SoOneShot class is a timer that runs for a configurable time and then stops.
   class SoOnOff
       The SoOnOff engine is a simple on/off switch.
   class SoEngineOutputData
       The SoEngineOutputData class is a container for a prototype set of outputs.

       This class is instantiated once for each class of objects which use outputs, and which
       needs to be able to import and export them. "
   class SoSelectOne
       The SoSelectOne class is used to select one value from a set of values.

       The output field will be the index'th value of the input multivalue field. "
   class SoTexture2Convert
       Abstract base class for texture filtering engines.
   class SoTimeCounter
       The SoTimeCounter class is an integer counter engine.

       The SoTimeCounter engine is by default connected to the realTime global field, and does
       stepwise updates on the SoTimeCounter::output field according to the field settings. "
   class SoTransformVec3f
       The SoTransformVec3f class transforms 3D vectors by a matrix.
   class SoTriggerAny
       The SoTriggerAny class is a fan-in engine for triggers.

       When any one of the input triggers are 'pulsed', any field connected as a slave to the
       engine output will be notified. "
   class SoEngineList
       The SoEngineList class is a container for SoEngine objects.

       As this class inherits SoBaseList, referencing and dereferencing will default be done on
       the objects at append(), remove(), insert() etc. "
   class SoEngineOutputList
       The SoEngineOutputList class is a container for SoEngineOutput objects.

Detailed Description

       Engines are scene based objects that convert between field values of various types or
       performs computations on them. The most versatile engine is the SoCalculator engine, which
       you can write your own mathematical expressions to to get it to do almost anything. The
       other engines are more custom-tailored for specific purposes.
