Add a Trajectory Model

Instructions for use

The Trajectory Model function is used to add third-party Model Data to the specified KML layer, which can dynamically demonstrate the process of model movement along the specified trajectory by drawing or selecting a route. The format of the third-party data model that can be loaded into the scene is: *.fbx, *.3ds, *.obj, *.dae, *.x, *.osgb, *.stl, *.off, *.gltf, *.glb, *.s3mb, *.osg, *.s3m.

Function entrance

  • Object Drawing Tab-> Model Object Group-> Track Model Button
  • Layer Manager->KML LayerContext Menu- > Add- > Trajectory Model

Operation steps

  1. If a KML Layer has been added to the current scene, make sure the KML Layer is editable. If there is no Add KML Layer in the current scene, you can right-click Normal Layer under Layer Manager . Select "New KML Layer" "or" Add KML Layer "" in the pop-up menu to create or add KML Layer.
  2. Add a dynamic model to a KML Layer in three ways:

    • On the Object Drawing tab Model Object group, click the Trajectory Model button and open the 3D Model Data File "dialog. In the Open 3D Model Data File "dialog box, select the Model File to which you want to add third-party data, and then click the Open button in the dialog box.

    • Right click on the KML Layer, and in the pop-up Context Menu, select the Track Models.. In the Add menu. The Open 3D Model File "dialog box pops up. In the Open 3D Model Data File" dialog box, select the Model File to which the third-party data is to be added, and then click the Open button in the dialog box.

    • In The Layer Manager ", select an object in KMLLayer, right-click, and select the Attribute item in the pop-up Context Menu. Select the Track Management "in the pop-up KML Properties" panel to add an object motion trail.

  3. Move the mouse to the scene, change the mouse status, click the left mouse button to start drawing a line in the scene as the trajectory, and click the right mouse button to end the drawing.
  4. After adding the Trajectory Model, the Application will pop up the KML Properties "panel automatically, and the Track Management" of the panel provides the relevant settings for trajectory and animation playback.
  5. The toolbar in the Track Management "panel provides operations related to track drawing, selection, visibility, and deletion, as described below:
    • Draw Track: Click the button in the toolbar and move the mouse to the scene to draw a polyline as the model motion track.
    • Select Track: Click the button in the toolbar to select a 3D line in the scene as the model motion track.
    • Show: Click the button in the toolbar to control the display of the motion track in the scene.
    • Delete: Click the button in the toolbar to delete the motion trajectory of the selected model in Layer Manager.
  6. The distance at the Track Info "that shows whether the model creates tracks and motion trails. Distance unit is meters.
  7. "Play Settings" provides settings such as playing time, speed and Loop Valid of the animation. The specific operation instructions are as follows:
    • Duration: It is used to display and set the playing time of node animation. The unit is second, and the default duration is 10 seconds.
    • Speed: used to display the movement speed of and Set Model from the start point to the end point of the trajectory, in m/s.
    • Loop Valid: When this check box is selected, the Playback operation will be repeated until the user stops playing when the track motion playback is executed; if this check box is not selected, the playback will be stopped after one playback when the Playback operation is executed.
  8. Playback controls are provided at the bottom of the panel to start, pause, or stop playback:
    • " Start/Pause" button: Click the button to play the effect of the model running according to the set track; click the button to pause the play.
    • " Stop" button: Click the button to stop the playback of the model track, and the model in the scene will switch to the starting position of the path.
Caution:
  • If you add a track by drawing lines in the scene, the default is not Show, you need to click the Track Visible button in the Track Management "to make it visible.
  • If Method 3 is used to add the result Model Data of 3D Optimal Path Analysis result saving, the KML Layer Settings should be set to editable state first, and then select Model Object in Layer Manager. You can set the trajectory to be visible in the Track Management "panel, and then you can dynamically demonstrate the movement of the model along the trajectory.
  • Currently, 3D Scene Rendering Engine V2 does not support adding Trajectory Model to KML Layer.
