Standard mode

In this chapter, we’ll delve into the user interface of DataMesh One in standard mode, as well as the features it contains. You’ll learn how to navigate and use DataMesh One in standard mode, including resource positioning, resource editing, and opening resources and scenes.

User interface

Main interface

Resources

The Resources tab contains all the folder directories and resource files that your account has access to. These resource files include 3D models, scenarios, images, PDF files, and more. The resource type of each file is indicated in the top-right corner of its respective resource file.

The following figure shows the toolbar found in the Resources tab:

• • Filter: Users can filter resources by tags. After selecting a tag, the resource list will display all resources associated with that tag.
  • Scan: Users can quickly view a resource by scanning the QR code for the resource using the DataMesh One standard mode (the QR codes for resources are provided on the FactVerse platform). Note: Users must have access permissions for the corresponding directory. For more details, please refer to the section Scan QR code to open resources.

Events

The Event tab is used to manage all the events that the current account has access to. In the Event tab, you can browse the event list, view event details, participant information, and scenarios. If you are the creator of the event, you can also edit the event.

The following figure shows the toolbar of the Events tab:

• • Refresh: Click the Refresh button to update the event list.
  • Add: Click the Add button to create a new event.

Scenes

DataMesh One provides access to scene files that are created in FactVerse Designer. A user who has permission for the Digital Twins module can view the scene interface directly in the application. The scene tab contains all folder directories and scene files the current account can access.

Settings

Clicking on the gear icon on the top right takes you to the application’s settings, where you can find general settings like account, browse mode, appearance, language, watermark, cache, and features such as uploading logs to our servers.

Browse Mode: If the user has permission for both Standard Mode and Training Mode, they can switch between modes in the settings. If the user only has permission for one mode, this option will not be displayed in the settings.

Language:  DataMesh One supports Simplified Chinese, English, Japanese and Traditional Chinese.

Appearance: This option allows the user to swap between the light mode and dark mode interface. The default appearance is Light.

Rendering Quality: To adapt to different device performance, DataMesh One provides six different rendering quality options. Increasing the quality can optimize screen aliasing, ripple, and shadow effects.

Position Reference: The position reference setting aligns the content displayed by DataMesh One in positioning mode with the target object in the real world to achieve positioning effects. Note: this option will not be displayed on the PC side.

• • Current Frame: Positioning is based on the current playback content of the scenario.
  • First Frame: Positioning is based on the first frame of the first scene of the scenario. For example, if A model is added in the positioning mode of the DataMesh Studio scenario, A model will be displayed for positioning under the initial positioning settings.

Watermark: Supports turning the watermark on/off. (Trial accounts and demo mode do not support turning off the watermark).

MR: This toggles the viewing modes between Mixed Reality (MR) and 3D. When using DataMesh One on mobile devices, MR mode is enabled by default, and you can switch to 3D viewing mode by turning off the MR switch in the settings. When using DataMesh One on a PC, only 3D mode is supported, and MR mode is not supported.
