Scenes

< All Topics

Scenes in DataMesh Studio are the smallest unit of a scenario, with each containing various roles such as 3D models, pictures, videos, music, light sources, and cameras.

Scenes allow you to customize the structure of your scenarios, and you can easily switch between different scenes to ensure consistency and smooth transitions. In addition, you can group scenes together to form chapters, which can help you better organize your scenario.

To manage scenes in DataMesh Studio, you can perform the following operations:

    • Create a new scene: Click the + button in the timeline to add a new scene at the end, or right click on a scene in the timeline and select Add Scene to add a new scene to the right of the selected scene.
    • Delete a scene: Right-click on the scene in the timeline and select Delete Scene.
    • Rename a scene: Select a scene in the timeline and click the edit button in the attributes pane to rename the scene.

In DataMesh Studio, the workspace offers various functions to help you adjust and explore scenes efficiently.

You can change your view of the workspace by dragging and zooming. Here are some fundamental operations:

Orbiting

To change your view of a scene around a central point, follow these steps:

1. Press and hold the right mouse button anywhere in the workspace. The cursor will change to a magnifying glass, and a blue highlight will appear.

2. Move the mouse in any direction to rotate your view around a central point. This allows you to observe models from different angles, providing a comprehensive view of the scene.

Panning

To move your view on a horizontal plane without changing its angle, follow these steps:

1. Click on an empty space within the workspace.

2. While holding down the left mouse button, drag the mouse to the left, right, up, or down on the screen.

3. Alternatively, you can press and hold the mouse wheel instead, leaving your left click free to perform other actions.

View height

To raise or lower your view, follow these steps:

1. Press and hold the Shift key on your keyboard.

2. Click and hold the left mouse button in an empty area of the workspace.

3. Move your cursor up to raise your view or down to lower your view.

Zoom

To zoom in or out of a scene, you can use the scroll wheel on your mouse. Here are the steps:

1. Place the mouse cursor over the workspace.

2. Scroll up to zoom in on the scene.

3. Scroll down to zoom out of the scene.

Focus

The focus function is used to center your view on a specific role, or on the very center of the virtual environment.

The focus function includes the following operations:

  • Scene focus: When there is nothing selected, click the Focus button located in the top right corner of the workspace to return your view back to its original starting position, which is centered at the very middle of the virtual environment.
  • Role focus: After selecting a role, click the focus button in the top right corner of the workspace to focus your view on the role from the front, and at a slightly elevated position. You can also do this by double-clicking the role in the roles pane at the bottom left of the screen, and focusing on an already focused subject moves your view even closer.

View cube

The View Cube is in the top right corner of the workspace and consists of six sides representing view angles from the front, back, left, right, top, and bottom. This allows users to quickly center their view on selected roles from different directions. In addition, the cube provides an intuitive visual reference for which direction you are facing, ensuring that users can easily reorient themselves when they need to.

The view cube allows you to center your view on either the scene, or a selected role:

    • Centered on the scene center: If no role is selected, clicking on any face of the cube will focus your view onto the scene center from the direction that the face corresponds to.
    • Centered on the role: If a role is selected, clicking on any face of the cube will focus your view onto the role from the direction that the face corresponds to.

Projection modes

DataMesh Studio supports two projection modes: perspective projection and orthographic projection.

To switch the projection mode of the scene, you can click the projection toggle button in the workspace.

1. Perspective Projection (Default)

Perspective projection is a projection mode where objects appear smaller when they are farther away from your view, and larger when they are closer.

2. Orthographic Projection

Orthographic projection is a projection mode where objects are the same size regardless of the distance away from your view. This provides a more technical view of the scene and is helpful when you want to easily access roles that are far away.

In scenarios with consecutive scenes in different locations, or if you would like to utilize dynamic camera movement, scene transitions are crucial for controlling the flow of the scenario.

In DataMesh Studio, there are several different ways to set scene transitions:

1. Attributes pane: You can configure scene transitions directly in the attributes pane. This allows you to define the transition type and specify the target scene. For more information, please refer to Set scene attributes.

2. Buttons: This allows viewers to navigate between scenes while the scenario is playing. For more details, please refer to Button.

3. Roles: Links allow you to give roles navigational properties when interacted with. For more details, please refer to Link.

When you click the empty space in the workspace, the attributes pane will display the scene attributes.

The attributes of a scene will be shown as follows:

A. The scene name, along with a button  that allows you to rename the scene

B. Scene Switch:

a). When you Tap: When the user clicks on the scene, it will transition to the next scene.

b). Auto Switch, After: This allows you to set a timer that every scene will follow, which is useful when you want every scene to be the same length. Once the timer runs out, the scenario will automatically progress to the next scene.

c). After checking: The scenario will automatically transition to the next scene once the specific checkbox is checked by the user.

C. Ground opacity: Change the opacity of the ground in the scene.
