Visualizing and Manipulating Temporal Information

Once you start drawing any path for one of the vehicles, the temporal information is automatically generated in parallel (see Animation 1). Thereby, the velocity profile is calculated in a way to drive as fast as possible on the drawn path. Any desired modifications can be inserted manually.

Visualize a specific timestamp

When moving the cursor above the temporal window, the corresponding vehicle poses are highlighted in the main window, as shown in the animation below. That way it is possible to visualize the vehicle arrangement at any timestamp.

Modify the velocity profile of an entity

In order to modify the velocity of a certain vehicle manually, first select the vehicle in the ‘Scenario GUI’ window. The corresponding temporal plots in the ‘Temporal Plot’ window will be highlighted with a bold stroke. Furthermore, the spacial velocity profile will hold black dots that can be dragged up and down with the mouse in order to alter the velocity profile. When holding and dragging a point sideways it is possible to batch process multiple points in a linear manner. The velocity and acceleration profile is updated, once the mouse button is released. This process is demonstrated in the animation below.

Static visualization of temporal information

Use the checkboxes ‘All Poses’ and ‘Add Text’ in the main window to display poses of the vehicles with a fixed temporal spacing (default: every 1s - change this parameter in the config). Thereby, the ‘Add Text’ checkbox toggles the text description next to every pose (NOTE: Due to performance issues, the text is displayed only for vehicles not currently selected in the entity selector).

In order to plot the information displayed in the main window, it is possible to open with the button ‘Open Plot’ an external window with the plot axis only (all GUI elements are removed) - e.g. useful for presentations or publications.
