Basics
Concepts
Digital Twin Template
A digital twin template defines a category of digital twins. Each template includes Metadata, Simulation logic, and Roles for a specific type of digital twins, allowing the creation of similar digital twins using the template.
Metadata represents abstracted structures and their properties. It is derived and summarized from real objects, serving as structured data to describe various characteristics and content of real objects.
Simulation logic or operational logic refers to a series of decision-making processes to realize the operational logic of the digital twin. The simulation logic supported by FactVerse Designer is based on behavior trees to enable discrete simulation. It allows the digital twin to make decisions based on various environmental data.
Roles refer to 3D resources such as models, constituting the three-dimensional appearance of the digital twin template. Digital twins created from a template will inherently possess the appearance defined by this template.
Digital Twin
Digital twin is an equivalent mapping of a specific entity in the physical world in the information world. Each digital twin is a specific instance of a digital twin template.
Digital twin attributes
Attributes refer to the collective nature and features of a digital twin, covering various aspects such as production information, appearance attributes, status information, and purpose-related attributes.
-
- Production information attributes: Used to describe the production information of the digital twin, such as model, batch, manufacturer, production date, etc.
- Appearance attributes: Used to define the visual characteristics of the digital twin, including color, material, size, position, etc.
- Status attributes: Used to express the operational status of the digital twin, indicating whether it is in operation, experiencing malfunctions, undergoing maintenance, etc.
- Purpose attributes: Describe the performance and characteristics of the digital twin under specific purposes, such as production and processing efficiency, energy consumption, decibels, temperature during operation, etc.
- Relationships between digital twins: Additionally, through the attribute pane, you can define relationships between digital twins. For example, specifying production relationships, processing relationships, transportation relationships, storage relationships, and disposal relationships between digital twins.
These attributes need to be defined using appropriate data types, including the following:
|
Type |
Definable attributes |
|
Int |
Quantity, frequency, speed, etc. |
|
Double |
Temperature, humidity, power consumption, balance, mass, area, etc. |
|
String |
ID, model, etc. |
|
Bool |
Operational status, check status, execution results, etc. |
|
Vector3 |
Placement position, placement angle, path positions, etc. |
|

|
Path |
Moving paths, transfer paths, transport paths, etc. |
|
Date |
Production date, maintenance date, etc. |
|
Time |
Start time, landing time, stop time, etc. |
|
Color |
Appearance colors, status colors, etc. |
|
Enum |
Error codes and error types, product codes and product categories, etc. |
Behavior Tree
A behavior tree is a structure similar to a decision tree used to select appropriate actions based on environmental data. The behaviors in most behavior trees are driven by digital twin data, with the aim of modifying digital twin data. Behavior trees can be bound to digital twins or scenes. The execution process of a behavior tree involves traversing the tree, following a top-down, left-to-right execution sequence.
Behavior tree nodes
In FactVerse Designer, a behavior tree is composed of different types of nodes, including Root Node, Composite Nodes, and Action Nodes.
-
- Root Node: When creating a behavior tree, a root node is automatically generated, serving as the starting point for the execution of the behavior tree. The root node cannot be deleted and can only connect to one child node.
- Composite Nodes: Composite Nodes are used to organize and control other nodes. They act as flow control nodes, defining how the branches of the behavior tree are executed based on specific rules. Composite Nodes can be nested within each other. Composite Nodes cannot act as leaf nodes and can have two types of return values: success and failure.
- Action Nodes: Action Nodes represent specific behaviors or tasks of the digital twin, such as moving along a path or waiting. Action Nodes are the leaf nodes of the behavior tree, where complex logic can be implemented. When an action node is executed, it performs a specific action and returns one of the following three return values:
-
-
- Success: Indicates that the node has been executed successfully.
- Running: Indicates that the node is still running, and it will continue to run when the behavior tree is called again.
- Failure: Indicates that the node has failed to execute.
-
Node execution rules
-
- The behavior tree is executed from top to bottom and from left to right.
- When the behavior tree reaches a terminal state, it returns to the Root Node and starts executing again.
- The Root Node can only have one child node.
- When a node has child nodes, it executes its child nodes first, from left to right. After all the child nodes have been executed, it moves on to the next node.
- The behavior tree runs in a continuous loop according to the specified sequence unless it is in idle mode or has been deleted.
Node operations
Add nodes
Drag and drop nodes from the Node Menu into the Editing area.
Delete nodes
Select the node to be deleted in the Editing area and click the delete button on the toolbar.
Rename nodes
Select the node to be renamed in the Editing area and enter the new name in the node name area above the Attribute Pane.
Connect nodes
To connect Node A with Node B, drag a yellow connection line from the bottom of Node A and connect it to the top of Node B. Release the mouse to complete the connection.
Organize nodes
Select the Root Node and press the “L” key to automatically organize the tree’s format.
Node condition
Conditions
Node conditions refer to the criteria that must be met for a node to be executed. If the conditions are met, the node is executed; if not, it will not be executed and will return to its parent node.
The icon of conditions in the Behavior Tree Editor: 
Condition groups
A condition group consists of multiple conditions within the group, and they are combined with the “AND” relationship. This means that all conditions within the condition group must be met for the node to execute.
The icon of condition groups in the Behavior Tree Editor: 
Multiple condition groups
A node can have multiple condition groups. The relationship between two condition groups is “OR.” This means that as long as one of the condition groups is satisfied, the node can execute.
The icon of condition groups in the Behavior Tree Editor: 
Digital twin scene
A digital twin scene is a virtual view of a business environment composed of instances of digital twins. It may also include customized business logic and 3D decorative elements. The core of a digital twin scene is its layout, primarily focusing on how to organize digital twins.
Key functions of a digital twin scene include:
- Positions of digital twins
- Connection relationships between digital twins
- Path planning
- Global operational logic

Users can drag nodes into the editing area, organizing them into a tree-like structure, and define the relationships and order between nodes. Users can adjust the positions of nodes and connect the lines between nodes. By working in the Behavior Tree Editing Area, users can intuitively build and modify the structure of the behavior tree.
Attribute Pane
The Attribute Pane is located on the right side of the Behavior Tree Editor interface and is used to set the attributes and execution conditions of behavior tree nodes. When a user selects a node, the Attribute pane displays the relevant attributes and conditional parameters of that node, which the user can set and adjust. The Attribute Pane also allows users to define the execution conditions of nodes, i.e., under what circumstances the node should be executed or skipped. By setting the execution conditions of nodes, users can control the behavior and execution logic of nodes based on specific conditions.
Virtual Factory DLC
The Virtual Factory DLC is a digital twin content expansion package introduced by DataMesh, primarily targeting discrete manufacturing factories. By leveraging digital twin technology, it aims to improve the efficiency of execution in different business processes, including production planning, operation supervision, and layout planning, while also reducing overall manufacturing operational costs.
The Virtual Factory DLC includes common factory elements such as source, conveyor belts, converters, AGV carts, and operator. Subscribers to FactVerse Designer can use these preset factory elements directly when creating scenes or customize them based on this DLC to meet specific requirements.
Virtual Factory DLC content
Models
The models in the Virtual Factory DLC serve as background and decorative elements in scenes, enhancing the realism of digital twin scenes. These models can also serve as the foundation for customized digital twin templates, allowing users to create specific types of digital twins, such as equipment and operators.
The Virtual Factory DLC includes several types of models:
-
- Background models: These three-dimensional models serve a decorative or background role in scenes or environments, enhancing the realism and visual appeal of the setting without serving as the primary interactive elements. Examples include factory backgrounds, storage boxes, stacks, and operating stations.
- Product models: Representing different types of products, each color and shape signifies a different product category. Examples include yellow balls, red cubes, and finished plastic boxes.
- Production equipment models: These models represent various production and transport equipment, including conveyor belts, robot, AGV, etc., used to simulate and display the actual equipment used in factories.

- Primary logistics line: This scene allows users to simulate and learn basic logistics line operations and management, including processes such as raw material generation and transport.
- Conditional sorting scene: This scene focuses on simulating the conditional sorting process, enabling users to understand and optimize material sorting operations under specific conditions. Users can configure the behavior tree of the sorting equipment through drag-and-drop, understanding the ability to sort based on the coordination of the behavior tree and digital twin attributes.
- Robot sorting scene: In this scene, users can delve into the operation of robot in the sorting process, including precise grasping and placing of materials. By dragging and dropping the behavior tree mechanism of the robot, users can understand the ability to express actual motion actions of the device through model animations.
- Transparent factory: A digital twin transparent factory refers to the real-time monitoring, analysis, and visual representation of a factory’s production process, equipment status, product quality, etc., through digital technology. This comprehensive transparency enables the entire factory’s production and operations to be visualized. The foundation of a digital twin transparent factory lies in digital twin technology, which precisely corresponds the physical factory to a digital model, allowing for comprehensive simulation and optimization of the factory’s production.
