Landscape in cuboid driving scenario generation

Is it possible to generate some sort of landscape based on the road geometry in cuboid driving scenario? Or do we need to self-generate using faces & vertices cuboid setting?

Hello Paul,

In a “Cuboid Scenario Simulation” in MATLAB, you can create a road network with specified road segments, lanes, and add objects like cuboids or other vehicles, generating a detailed landscape or terrain based on the road geometry is not a built-in feature.If you want to create a realistic landscape or terrain that matches the road geometry, you will typically need to use external data sources or tools to generate or import terrain data.

Here are some steps you can follow to integrate terrain with your cuboid driving scenario:

1. Terrain Data Source: Obtain terrain data from a suitable source. This could be digital elevation data (elevation maps) or 3D terrain models.
2. Import Terrain Data: Depending on the format of the terrain data, you may need to import it into MATLAB. MATLAB has functions for reading various file formats, such as “GeoTIFF” for elevation data.
3. Terrain Visualization: Visualize the terrain using MATLAB's visualization capabilities. You can use functions like ‘surf’ or ‘mesh’ to display the terrain surface.
4. Align with Road Geometry: Align the terrain data with the road geometry. You would need to position and orient the terrain so that it matches the road's location and elevation. This may involve translating and rotating the terrain data.
5. Simulation and Visualization: Finally, integrate the terrain into your cuboid driving scenario and simulate the entire environment. You can use MATLAB's visualization tools to view the combined landscape, road, vehicles, and objects.
