Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical
Commission) form the specialized system for worldwide standardization. National bodies that are members of
ISO or IEC participate in the development of International Standards through technical committees
established by the respective organization to deal with particular fields of technical activity. ISO and IEC
technical committees collaborate in fields of mutual interest. Other international organizations, governmental
and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information
technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of the joint technical committee is to prepare International Standards. Draft International
Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as
an International Standard requires approval by at least 75 % of the national bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights.
ISO/IEC 14496-27 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology,
Subcommittee SC 29, Coding of audio, picture, multimedia and hypermedia information.

Introduction
This part of ISO/IEC 14496 (MPEG-4) contains the description of all conformance bitstreams developed for
the synthetic 3D graphics tools published in the following four other parts of MPEG-4: ISO/IEC 14496-11:2005,
ISO/IEC 14496-16:2006, ISO/IEC 14496-21:2006 and ISO/IEC 14496-25:2009. This part of ISO/IEC 14496
also describes how tests can be designed to verify whether compressed data (i.e. bitstreams) and decoders
meet the requirements specified for synthetic 3D graphics tools by those four International Standards.

INTERNATIONAL STANDARD ISO/IEC 14496-27:2009(E)

Information technology — Coding of audio-visual objects —
Part 27:
3D Graphics conformance
1 Scope
This part of ISO/IEC 14496 specifies how tests can be designed to verify whether compressed data
(i.e. bitstreams) and decoders meet the requirements for the synthetic 3D graphics tools specified in
ISO/IEC 14496-11:2005, ISO/IEC 14496-16:2006, ISO/IEC 14496-21:2006, and ISO/IEC 14496-25:2009.
This part of ISO/IEC 14496 does not specifically address encoders. As far as synthetic 3D graphics are
concerned, an encoder can be said to be an ISO/IEC 14496 encoder if it generates compressed data
compliant with the syntactic and semantic bitstream payload requirements specified in ISO/IEC 14496-11,
ISO/IEC 14496-16, ISO/IEC 14496-21, and ISO/IEC 14496-25.
Characteristics of coded bitstreams and decoders are defined for ISO/IEC 14496-11, ISO/IEC 14496-16,
ISO/IEC 14496-21, and ISO/IEC 14496-25. The characteristics of a bitstream define the subset of the
standard that is exploited in the bitstream. Examples are the applied values or range of the bitrate. Decoder
characteristics define the properties and capabilities of the applied decoding process. An example of a
property is the applied arithmetic accuracy. The capabilities of a decoder specify which coded bitstreams the
decoder can decode and reconstruct, by defining the subset of the standard that may be exploited in
decodable bitstreams. A bitstream can be decoded by a decoder if the characteristics of the coded bitstream
are within the subset of the normative references.
This part of ISO/IEC 14496 describes procedures for testing conformance of compressed data and decoders
to the requirements defined in ISO/IEC 14496-11, ISO/IEC 14496-16, ISO/IEC 14496-21, and
ISO/IEC 14496-25; given the set of characteristics claimed, the requirements that shall be met are fully
determined by these parts.
This part of ISO/IEC 14496 summarizes the requirements, cross references them to characteristics, and
defines how conformance with them can be tested. Guidelines are given on constructing tests to verify
decoder conformance.

4.1.2.4 Tolerance
There is no tolerance. The diagnosis is pass or fail.
4.1.3 Rendering conformance
4.1.3.1 Conformance requirements
All tools with non-trivial algorithms shall be tested for rendering conformance.

Procedural textures are a function of the supplied parameters.
While rendering is not required to be color exact - color depth will vary between terminals - the texture
structure must be pixel exact. In particular the (distorted) cell outline, cell positioning, and the interior of
plasma based textures must be preserved.

4.2.2 Geometry bitstreams
4.2.2.1 3DMC extension
The 3D mesh object is a 3D polygonal model that can be represented as an IndexedFaceSet in BIFS. It is
defined by the position of its vertices (geometry), by the association between each face and its sustaining
vertices (connectivity), and optionally by colours, normals, and texture coordinates (properties). Properties do
not affect the 3D geometry, but influence the way the model is shaded.
3D mesh coding (3DMC) extension addresses the efficient coding of 3D mesh object. It comprises a basic
method and several options. The basic 3DMC extension method operates on manifold model and features
incremental representation of single resolution 3D model. The model may be triangular or polygonal – the
latter are triangulated for coding purposes and are fully recovered in the decoder. Options include: (a) support
for error resilience; (b) vertex order and face order preserving; (c) efficient texture mapping; and (d) support
for non-manifold and non-orientable model.
4.2.2.1.1 Conformance points
4.2.2.1.1.1 Covered functionalities
The conformance points for compression of 3DMC extension cover basic compression, backward
compatibility, forward compatibility, error resilience support, backward compatibility with error resilience,
forward compatibility with error resilience, vertex order and face order preserving, support of non-
manifold/non-orientable model (stitch), and efficient texture mapping. These functionalities relate to the
compressed representation of the IndexedFaceSet node carried by the BitWrapper node as described in
7.2.2.23 of ISO/IEC 14496-11:2005.
As for carriage of compressed representation by the IndexedFaceSet node using the BitWrapper node, it can
be carried either in a separate stream or within the scene stream (BIFS stream). Therefore, compression of
3DMC extension shall also be tested together with this node.
The following Subclauses specify the normative tests for verifying conformance of 3DMC extension
compressed bitstreams and 3DMC extension decoder. Those normative tests make use of test data
(bitstream test suites).
4.2.2.1.2 Bitstream conformance
4.2.2.1.2.1 Conformance requirements
BIFS streams shall comply with the specifications for compression of 3DMC extension in
ISO/IEC 14496-16:2006/Amd1:2007 and 7.2.2.23 of ISO/IEC 14496-11:2005.
4.2.2.1.2.2 Measurement procedure
Syntax of the BIFS stream shall meet the requirements of compression of 3DMC extension in
ISO/IEC 14496-16:2006/Amd1:2007 and 7.2.2.23 of ISO/IEC 14496-11:2005.
4.2.2.1.2.3 Tolerance
There is no tolerance for bitstream syntax checking. The diagnosis is pass or fail.

4.2.2.1.3 Terminal conformance
4.2.2.1.3.1 Conformance requirements
A compliant decoder shall implement a decoding process that is equivalent to the one specified in
ISO/IEC 14496-16:2006/Amd1:2007 and meets all the general requirements, defined in the document, which
apply for the functionalities considered. The decoder shall decode bitstreams with any options or parameters
with values permitted for the functionalities. In the case of using BIFS for scene representation, the decoding
process that is specified in Clause 8 of ISO/IEC 14496-11:2005 shall also be implemented.
