Sensor Visualizers

When in a non-Headless Simulation, sensor visualizers can be toggled from the menu. To visualize a sensor, click the "eye" next to the sensor name.

Sensors are identified by the name parameter from the JSON configuration. For full details on the possible JSON parameters see Sensor Parameters Not all sensors have visualizations available, only sensors who have will show their visualizations.

Cameras top#

When a camera is visualized, the image the sensor see is visualized in a window. This window can be resized by clicking-and-dragging the icon in the bottom right corner and can be made full-screen with the box icon in the top right corner. The window can be moved by clicking-and-dragging the top bar. To close the window, either click the X or click the "eye" again.
