Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. Each member body interested in a subject for which a technical committee
has been established has the right to be represented on that committee. International organizations,
governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely
with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO document should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

related to conformity assessment, as well as information about ISO's adherence to the World Trade
Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www.iso.org/iso/foreword.html.

Introduction
0.1  PDF: ISO 32000
ISO 32000-2 can embed 3D Computer-aided design (CAD) models as either 3D or RichMedia annotations.
3D node, stream and view dictionaries can only reference data saved in either the ECMA-363 [Universal 3D
(U3D) file format] or ISO 14739-1 [the Product Representation Compact (PRC) file format]. This can require
the authoritative CAD data to be translated to either U3D or PRC solely to embed the data in a PDF file.
0.2  glTF: ISO/IEC 12113
glTF is an open, royalty-free 3D asset delivery format designed and managed by the Khronos Group, which is
a Standards Developing Organization (SDO).
The specification for glTF 2.0 is published as ISO/IEC 12113:2022.
0.3  Extending PDF to support glTF
The purpose of this document is to extend the PDF specification to allow RichMedia annotations to include
3D artworks saved in the glTF format.

RichMedia annotations conforming to glTF assets
1 Scope
This document specifies how to extend the ISO 32000-2 specification by adding the ISO/IEC 12113 (glTF)
format as a valid format for 3D artworks contained in a RichMedia annotation. It is intended for:
— developers of software that creates PDF files (PDF writers);
— software that reads existing PDF files and usually interprets their contents for display (PDF readers);
— software that reads and displays PDF content and interacts with the computer users to modify and save
the PDF file (PDF processors);
— PDF products that read and/or write PDF files for a variety of other purposes (PDF processors).
NOTE PDF writers and PDF readers are more specialized classifications of PDF processors.
This document does not specify the following:
— specific processes for converting paper or electronic documents to the PDF file format;
— specific technical design, user interface implementation, or operational details of rendering;
— specific physical methods of storing these documents such as media and storage conditions;
— methods for validating the conformance of PDF files or PDF processors;
— required computer hardware or operating systems.
