This is a partial implementation of the ASAM Open Drive specification, it is purely done for educational purposes, it is not designed to be fast, complete and/or efficient. There are some example files included as well as a Jupyter Notebook to visualize the resulting mesh.
The coverage of the spec is far from complete, but the basic features are implemented and it can be further extended for complete coverage.
Notable short commings:
- For reference line geometry, only line/spiral/arc geometry is implemented, not the (legacy?) poly geometry
- Road height and superelevation is implemented, but there is no support for road shapes
- Lane width implemented using lane width only, border implementation for mesh generation not supported (not hard to do)
- Basic road marker support, the more detailed implementation is not supported
- No support for signals, objects, controllers, etc.
The mesh generation process uses a fixed step and samples each lane independently. This is necessary, since each lane can have individual height offsets, lane type and materials. A basic color coding is used to distinguish the lane types. The lane markers are also converted to a mesh individually and layed slightly above the road surface.
Support to convert to convert to an .obj or some other 3d modelling format is not yet implemented.
