Abstract base class for each state element whose value may be accumulated when it is set.
Abstract base class for all database nodes.
Definition SoNode.h:145
Traversal state.
Definition SoState.h:74
Stores the current volume transform(s).
static void get(SoState *state, std::vector< SoVolumeTransform * > &)
Get the current list of transform functions stored in the state.
static void set(SoState *state, SoNode *node, SoVolumeTransform *m_volumeTransformNode)
Add a volume transform to the state.
static void get(SoState *state, SoVolumeTransform *&m_volumeTransformNode)
Returns most recently traversed volume transform from the state.
virtual void push(SoState *state)
Overrides push() method to copy values from next instance in the stack.
