1      Definition

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

3D Model is specified by MMM-PAF V1.4.

2      Functional Requirements

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

  1. SubTypes
  2.  Formats
    1. Content
    2. Transport

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