7.3.1 Introduction

In ASAM OpenMATERIAL 3D, an object class is a collection of similar objects. Examples of object classes are vehicles, humans, and road networks. Each instance of an object class is described by the same properties, but has individual property values.

The ASAM OpenMATERIAL 3D standard supports the following object classes:

If a human is clearly distinguishable from a vehicle, then both the human and the vehicle are represented by two different objects respectively. Examples are bicycles, motorbikes, or scooters, where the human and the vehicle are perceived as separate entities.

The other object class comprises all objects not yet specified by ASAM OpenMATERIAL 3D. It includes all objects that aren’t specified by type specific object classes. Definitions in type specific object classes overwrite the specifications in the other object class.
