3D standards have been developed throughout the years for many different purposes: visualisation (fast and realistic), data management (efficient storage), modelling (validity and topology) or data exchange (platform independence). The developers also vary from companies to international standardisation organisations that originated from CAD/BIM, GIS or Web domains. Being developed with different goals, the information in them (such as type of geometry, textures, semantics, relationships) varies significantly and this makes the integration of data in a single 3D environment almost an impossible task. Many problems can be experienced when converting data from one standard to another: information may be lost or models may be improperly converted, validity of objects may not be ensured, relationships might be diminished, etc. This paper presents a comparative study of 3D standards with respect to a number of characteristics such as type of geometry, relationships, semantics, possibilities for realism, etc. The paper compares several well-known international and de facto standards. The characteristics of them are then discussed in the context of 3D models (and needed functionality) for (facilitating) emergency response.
