SoState
The SoState class manages the Coin scenegraph traversal state data.The SoState class is used by actio...
Definition: SoState.h:35
SoMField
The SoMField class is the base class for fields which can contain multiple values.All field types which may contain more than one member value inherits this class. SoMField is an abstract class.
Definition: SoMField.h:32
SoAccumulatedElement
The SoAccumulatedElement class is an abstract class for storing accumulated state.This is the superclass of elements where new element data accumulates with older data.
