1      Definition

3D Model Qualifier is a set of Data providing additional information on 3D Model Data for potential use by a machine.

The combination of 3D Model Data and 3D Model Qualifier is called 3D Model Object, specified by MPAI-OSD V1.3.

2      Functional Requirements

3D Model Qualifier allow the expression of the following Elements:

  1. Sub-Types
  2.  Formats
    1. Content
    2. Transport

Users needing additional entries in the3D Model Qualifier or support of new Qualifiers should make a documented request to the MPAI Secretariat. Requests will be considered by the appropriate MPAI committee.
