Scenarios

A scenario is a .dirpkg file created and edited in DataMesh Studio that consists of multiple scenes, each containing user-added models, pictures, attachments, text, and tools etc. In a scenario, not only you can compose and structure each scene, but also animate dynamic transitions in between the scenes. Scenario management is available in the Digital Assets module of the DataMesh FactVerse platform.

Change rendering environment

The rendering environment refers to the background lighting effects used to simulate light propagation, reflection, and refraction in the virtual environment. It influences the appearance, lighting, and shadow effects of objects, enhancing the overall realism and fidelity of the scenes.

In DataMesh Studio, you can choose either the built-in rendering environment or customize the rendering environment for scenario creation, making the virtual scene realistic and immersive.

To change the rendering environment of a scenario, you can follow these steps:

1. Click on the Scenario menu and select Change rendering environment from the dropdown menu. You can open the Change rendering environment window.

2. In the Change rendering environment window, you can choose the system-built rendering environments. When you choose “None”, there is no specific environment rendering effects.

You can also create a custom rendering environment to suit the scenario’s background and sky effects for different scene requirements and creative purposes.

Steps for custom reflection environment:

1. Prepare six images: These images should correspond to the front, back, left, right, top, and bottom directions of the rendering environment. The images should be in PNG format and follow English naming conventions (Front, Back, Left, Right, Top, Bottom).

2. Compress these images into a zip file and change its extension to .dmcm.

3. Upload this .dmcm file to the resource library on the DataMesh FactVerse platform.

4. In DataMesh Studio, click on the Scenario menu and select Change rendering environment from the dropdown menu to open the Change rendering environment window.

5. In the Change rendering environment window, select the Custom tab and click Select rendering environment.

6. In the window for Select rendering environment, find the uploaded .dmcm file.

7. After selecting the file, click the Confirm button to complete the customization of the rendering environment.

Manage scenario structure

In DataMesh Studio, the table of contents is used to display a list view of the structure of scenes chapters in the current scenario.

By clicking the table of contents button , you can browse the entire scenario, grasp the overall structure and chapter contents, and quickly jump to the desired chapters and scenes.

The following are the basic operations on the scenario structure:

• • Start New Chapter: Each chapter in the table of contents represents a group of scenes. To start a new chapter, you can right-click on a scene in the timeline, select New Chapter, and a window will appear. Type in the chapter’s name, and this will make the selected scene a starting point for a new chapter.

Keep Elements: This option is a checkbox found in the New Chapter window that toggles whether or not you keep the elements from the previous scene. When checked, all the elements remained where they were. When unchecked, this converts the scene into a completely blank slate by removing all of its elements.

• • Delete Chapter: To delete a chapter, right-click on the chapter name in the timeline and select Delete Chapter. This will remove the chapter and all its associated scenes from the table of content.
  • Rename Chapter: To rename a chapter in the scene catalog, right-click on the chapter name in the timeline and select Rename Chapter.
