However, if the portions are too small, UE will have too many objects to manage, and performance will be affected too. The smaller the portions, the more probably they are discarded. If a portion is not visible, UE will not render it. The mesh is divide in portions to reduce rendering overhead. max_road_length (default 50.0 meters) - Maximum length of a portion of the mesh.However, if the distance is too small, the resulting mesh will be too heavy to work with.
The bigger, the distance, the more inaccurate the mesh will be. vertex_distance (default 2.0 meters) - Distance between the vertices of the mesh.Parameters is a carla.OpendriveGenerationParameters containing settings for the generation of the mesh. opendrive is the content of the OpenDRIVE file parsed as a string.This will generate the new map, and block the simulation until it is ready. Open an OpenDRIVE file is just a matter of calling client.generate_opendrive_world() through the API. Any issues in it will propagate when running the simulation. It is especially important to double check the OpenDRIVE file. This could be an issue especially at junctions, where many lanes are mixed. xodr directly, any issues in it will propagate to the simulation. All of these elements, and every detail on the road, are based on the OpenDRIVE file. Pedestrians will navigate over the sidewalks and crosswalks that appear in the map. Traffic lights, stops and yields will be generated on the fly. Visible walls are created at the boundaries of the road, to act as a last safety measure.Lanes are a bit wider at junctions, where the flow of vehicles is most complex.In order to prevent vehicles from falling off the road, two measures have been taken. All the elements will correspond with the OpenDRIVE file, but besides that, there will be only void. The resulting mesh describes the road definition in a minimalistic manner.
#OPENDRIVE BANDWIDTH SIMULATOR#
To this end, the simulator takes an OpenDRIVE file and procedurally creates a temporal 3D mesh to run the simulation with.
#OPENDRIVE BANDWIDTH FULL#
This mode runs a full simulation using only an OpenDRIVE file, without the need of any additional geometries or assets. In order to do so, the simulator will automatically generate a road mesh for actors to navigate through.
