Parent object	An object in the hierarchy that is directly above other objects (sub-objects). The position, rotation, and scale of sub-objects are influenced by the parent object.
Action Sequence	A panel that manages all actions to be added in the scenario. The list is arranged in the order the actions are added and allows users to manage and edit them.
Appear	The initial action automatically generated for each element when added to a scene. This defines the element’s initial performance in the scene, including how it appears and its related settings.
Move	Actions that allow an element to transition from its original pose to a target pose within a specified time. These are used to adjust the position, rotation, and scaling of a model for dynamic changes or transitions.
Disassemble	This action evenly spreads out the sub-objects of the selected model. It’s commonly used to create dynamic effects.

Marker	A QR code used for virtual content localization. In the scenario, it stores position and rotation information, and scanning the code in the real world matches the virtual content to its real-world location.
Move	An operation assist tool used in scenario construction. When activated, the selected model or element displays three arrows pointing along the X, Y, and Z axes, allowing users to drag and move the object along these axes.
Hot Zone	An interactive area set after linking an action to an element. It’s typically a cube centered on the character. Users can adjust the size of the hot zone to define the interaction trigger area. When users click within this area, the preset action (such as scene transition) is triggered.
Central Location	When multiple elements are grouped together, this is the center point of the group. The system calculates the common center based on the positions of all elements, and rotations or movements are performed relative to this center.
Central Element	In a group of elements, selecting a specific element sets its center point as the reference for the group. Operations like rotation or movement are then performed based on this selected element’s center.
Projection Type	The method used in 3D design tools to render and display the scene. Common projection types are orthographic and perspective.
Orthographic Projection	A projection where all lines are parallel and perpendicular to the projection plane. It maintains the actual size of objects regardless of distance, which is useful for precision tasks.

Story node	The basic unit of a storyline, containing a scenario chapter and defining how nodes connect with each other. These nodes enable flexible control over the playback order, supporting nonlinear transitions.
Connection point	Key elements used to define the order in which story nodes are played. There are input and output connection points. When a node’s outgoing point connects to another node’s incoming point, it triggers an automatic transition from one node to the next.
Incoming point	A function point in a story node that defines the start of its playback. When another node’s outgoing point connects to an incomingt point, it triggers the start of that node’s content.
Outgoing point	A function point in a story node that defines the exit of playback. When the outgoing point connects to another node’s incoming point, it initiates a transition to the next node.
Transition point	A function point in a story node that allows for manual trigger jumps during playback. Unlike automatic connection points, transition points allow users to switch nodes during playback through interactive hot zone, enabling flexible control.
Canvas	The workspace for editing the storyline. Users can create, arrange, and organize story nodes visually, connecting them with connection points or transition points to define playback relationships and interactions.
Transition point name	Configurations for interactive objects (such as buttons or links) to initiate jump actions. These allow objects to trigger specific jumps, like switching to a story node and playing its associated chapter, enabling dynamic and interactive playback.
