Since the 3D graphics is recently very powerful and interesting, there are many systems of the character modelling to create the hierarchical structure of 3D human figures. Those systems have been developed for modelling the parts of the human respiratory internal organs with the critical names. In the system development, standards from the fundamental building blocks for the development by establishing consistent standard protocol that can be universally understood and adopted. Thus, this international standard defines the scope and key concepts to provide the respiratory organ model architecture of the human body. The relevant terms and definitions, and a generalized system architecture, generally serve as a reference model for human respiratory modelling and structure of a humanoid. This International Standard describes a standard way of representing humanoids that, when followed, will allow human skeletal hierarchical structure created with modelling tools from each organ and then apply those structures with their surfaces of the 3D object model. Also, it defines a set of principles, concepts, and functionalities for the respiratory organs to improve and upgrade the current standards. This reference model establishes the set of required modules and their minimum functions, the associated information content, and the information models that shall be provided and/or be supported by H-Anim, the modelling for representing of three dimensional human figures. This International Standard includes (but is not limited to) the following content:

The objectives of this work are as follows:

This International Standard has the following document structure:

In the prologue, the Foreword identifies the organization, and its nature, responsible for the establishment of the standard and the pertaining document publication. The Introduction gives a brief overview of the purpose and content of the document. This standard is comprised of:

  1. Scope defines the extent which this standard intends to cover.

  2. Normaltive references lists the normative standards referenced in this International Standard.

  3. Terms, definitions, and Abbreviated terms deifines the glossary of terminology and abbreviations used in this International Standard.

  4. Concepts of Structure Classification of the Human Respiratory Internal Oragans shows the hierarchical structure of internal organ based on Upper and Lower respirtory tracts.

  5. 3D Respiratory Organ Modelling Based on Hierachical Structure provides a way to make a system modelling or categorising by using hierachical structuring method.

  6. Comformance makes statements regarding any conformance related issues of a Internal Respiratory System.


This standard res. Moreover, it will provide functionalities and features including the concept and technique to create a structure as the architecture of the organs by using a tree structure. Another purpose is to provide a visualization method which gives critical names of the internal respiratory organs and tissues of the human body’s cells in a 3D scene with textures. Currently, the structure and hierarchy of humanoid are only represented partially in the human body such as hand, feet, and face of body’s components. This standard proposes to add a respiratory system part of humanoids to construct in the body architecture.
