MATLAB Functions for Scene Authoring

R2026b

Create and modify RoadRunner scenario elements, such as actors, logic phases, and waypoints, using MATLAB^®

Automated Driving Toolbox™ offers functions that enable you to programmatically author scenes in RoadRunner, such as by adding roads, modifying road geometry, and adding lanes and junctions, from the MATLAB command-line interface. By authoring scenes programmatically, you can quickly build scenes without switching between applications, automate repetitive authoring tasks, and generate scene variations for automated tests.
