User interface

The layout of DataMesh Importer user interface is as follows:

Toolbar

The toolbar includes options for File, Save, and Settings, allowing you to open local models, open cloud models, and save models.

Icon	Name	Function menu
	File	•         Open Local Model: Open a locally saved model file. •         Open Cloud Model: Open a model file from the FactVerse platform. •         Save Model: Upload the currently imported model to the FactVerse platform. •         Save As: Perform a Save As operation on the current model and specify a new name for it.
	Save	•         Save the model resource to the FactVerse platform.
	Settings	•         Language: You can switch to different interface languages. The DataMesh Importer offers four interface languages: Simplified Chinese, Traditional Chinese, English, and Japanese. After users log in, the interface language will default to the system language. If the system language is not one of these four application languages, the interface language will default to English •         Account > User account: Display current login user account. •         Account > Log out: Exit current user account •         Rendering quality: You can choose different rendering quality levels to adjust the clarity and level of detail in model rendering. o    1 (Lowest Quality): The most basic rendering level, ideal for quickly viewing the model or when the device performance is limited. o    6 (Highest Quality): The best image quality and detail display, but it may significantly impact software performance. •         Change Rendering Environment: Support modifying the rendering environment of the scene, which can include system-built rendering environments or custom rendering environments. For detailed information, please refer to the guide on Change rendering environment. •         Upload log: You can upload the latest seven log files to FactVerse. •         Performance Statistics: Displays key data such as Memory, FPS, DrawCall, Batches, Ploygons, and Vertices. •         About: View the current application version. •         Quit: Close the software.

Node directory

The Node directory is a feature in DataMesh Importer that displays the hierarchical structure and node relationships of the imported 3D models. The Node directory can help you better manage and control the structure of the imported 3D model. You can select, deselect, and merge nodes as needed to flexibly adjust the model’s hierarchical structure. This can improve the model’s operability and flexibility, making it easier for you to perform subsequent model editing and scene creation work.

In the Node directory, you can perform the following operations:

• • Smart Select All: With Smart Select All, you can quickly select or deselect all nodes for batch operations.
  • Single node selection: Each node has a checkbox that you can click to select or deselect the node. Through the checkbox, you can selectively control the components of the model. When you upload the model, the selected nodes will be uploaded as separate objects, while the unselected nodes will be merged into other nodes.
  • Select same-level nodes quickly: By double-clicking the checkbox of a node, you can quickly select or deselect all same-level nodes under that node. This feature makes it easier to select or deselect all nodes at the same level.

Note: When the number of nodes exceeds 500, you will need to manually select the nodes.

Scene area

The Scene area can load and display imported 3D models. Users can import various format model files (such as FBX, GLTF, OBJ, etc.) and present them as realistic 3D objects in the Scene area. Users can freely browse and observe the model in the Scene area.

When loading and displaying imported 3D models in the Scene area, users can use the following methods to adjust the scene perspective:

• • Rotate the scene: Hold down the right mouse button at any position in the scene and move the mouse horizontally to rotate the scene in all directions for a comprehensive view of the model.
  • Pan the scene: To move the scene to the left, right, forward, or backward in the scene, click on a blank area in the scene, hold down the left mouse button, and drag the mouse to the left, right, or up and down on the screen. You can also hold down the mouse wheel and drag the mouse in the direction you want to pan.
  • Zoom the scene: To zoom in and out of the scene, you can use the scroll wheel on the mouse. Scroll up to zoom in and scroll down to zoom out.
  • Raise and lower the scene: To raise and lower the scene, hold down the Shift key and the left mouse button, and move up and down on the blank area of the scene. Move up to lower the scene and move down to raise the scene.

Attribute area

The Model Attributes section shows how smoothly the current model runs on different platforms and provides its basic attribute details. It also includes tools for editing materials, allowing users to adjust properties like color and transparency to achieve the desired visual effects.

Attribute area features:

• • Supported Platforms: Displays how well the model performs in DataMesh applications on different platforms. Factors like texture count, resolution, and sub-node numbers can impact performance
  • Polygons: The polygons refer to the number of polygons in the model. It is an important indicator for measuring model complexity and detail level. Higher polygon counts usually mean more details and more refined appearance but may also lead to performance burdens. In DataMesh Importer, when the polygon count of the model is too large, it may affect the use of the application and give corresponding prompts.
  • Vertices: The model vertices refer to the total number of vertices in the model. Vertices are the basic building blocks of the model, forming polygons by connecting vertices, thus forming the entire model. The vertices are related to the detail and complexity of the model. A high vertex may increase rendering and computational burdens. Therefore, when using DataMesh Importer, if the vertices of the model are too large, prompts may be given.
  • Textures: The texture count refers to the number of texture images applied to the model. Textures can give the model visual effects such as color, texture, and reflection. Increasing the number of textures may increase memory usage and render burdens. In DataMesh Importer, the textures can provide an evaluation of the model’s texture usage, allowing users to understand the details of the model.
  • Materials: Lists the materials used in the model, defining attributes like color, transparency, metallicity, and smoothness. Users can edit these to improve the model’s appearance.
  • Information: Provides detailed attributes of the model or its nodes to help users quickly understand its status and features.
  • Animation: If the model includes animations, users can play them by clicking the animation play button.
