MATLAB Functions for Scene Authoring

Create and modify RoadRunner scene elements, such as roads, and lanes, using MATLAB® (requires Automated Driving Toolbox™)

MATLAB functions for scene authoring enable you to programmatically author scenes in RoadRunner, such as by adding roads, modifying road geometry, and adding lanes, 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.
