Non-rendering mode

[juaxix]

Changes to enable or disable rendering of the world (Unreal render) and CARLA HUDs (Unreal HUD rendering) using a property of the server settings.

The changes involve:

• Clients can use the DisableRendering flag
• Added the option in : Carla.Settings.ini -> [CARLA/Server] -> DisableRendering
• Added the argument for runtime : "-disable-rendering"
• Tests needed

Example

Using the code for manual_control.py, with this modification:

def make_carla_settings(args):
    """Make a CarlaSettings object with the settings we need."""
    settings = CarlaSettings()
    settings.set(
        SynchronousMode=True,
        SendNonPlayerAgentsInfo=True,
        NumberOfVehicles=15,
        NumberOfPedestrians=30,
        WeatherId=random.choice([1, 3, 7, 8, 14]),
        QualityLevel=args.quality_level,
        DisableRendering=True)
    settings.randomize_seeds()
    if args.lidar:
        lidar = sensor.Lidar('Lidar32')
        lidar.set_position(0, 0, 2.5)
        lidar.set_rotation(0, 0, 0)
        lidar.set(
            Channels=32,
            Range=50,
            PointsPerSecond=100000,
            RotationFrequency=10,
            UpperFovLimit=10,
            LowerFovLimit=-30)
        settings.add_sensor(lidar)
    return settings

we are removing all the sensors except for the lidar. We can launch the client with a command like this:

PythonClient$ python manual_control.py -a -l

Screenshot of the result :

Where has this been tested?

• **Platform(s): Windows and Linux
• **Python version(s): ** 2.6, 3
• Unreal Engine version(s): 4.18.3

Possible Drawbacks

You may want to draw huds?
