Industrial automation systems and integration — Product data representation and exchange — Part 46: Integrated generic resources: Visual presentation

Specifies the integrated resources for the visualization of displayable product information and the generic resources required to describe the desired visual appearance of product information in its picture. Covers association between product data and presentation data; support of graphics functionality in compliance with current ISO graphics standards; definition of presentation style attributes; control of approximation tolerances for geometric presentation elements; methods for defining the appearance of characters and symbols in fonts; support of externally defined character fonts and symbols; image control by a layer mechanism; nesting of presentation areas. Does not cover: Definition of product information and of the contents of character font and symbol libraries; exchange of purely graphical information without any relationship to product information.

Introduction
ISO 10303 is an International Standard for the computer-interpretable representation and ex-
Change of product data. The objective is to provide a neutral mechanism capable of describing
product data throughout the life cycle of a product independent from any particular System.

This International Standard is organized as a series of Parts, each published separately. The
description methods, integrated resources,
Parts of ISO 10303 fall into one of the following series:
application protocols, abstract test suites, implementation methods, and conformance testing.
The series are described in ISO 10303-1. This part of ISO 10303 is a member of the integrated
resources series. Major subdivisions of this International Standard are:
-
Present ation organization
-
Presentation definition
- Present ation
-
Present ation resources
This part of ISO 10303 specifies the integrated resources for the visualization of displayable
properties of products.
The information given in all four Schemas of this part together is sufficient to describe in detail
how product information shall be visualized by a receiving System. The present ation information
contained in this part tan be used only in conjunction with product informaDtion suitable for
display. Presentation information as contained in this part cannot be displayed by itself without
reference to product information.
The presentation organization Schema describes the hierarchical alnd partially recursive structure
of the presentation Sets, areas and views in which images of the product information are dis-
played. It also explains how the components of the product information image and its annotation
are organized as displayable objects and how these are placed into the context of presentations.
This Schema also accounts for the definition of the projective process for geometry by means of
a Camera model and for the specification of lighting and shading models.
The presentation definition Schema serves to define how the individual geometric and non-
geometric components of the product information are selected, assembled into presentation
groups, and associated with presentation styles.
The presentation appearance Schema defines the appearance attributes that ca,n be Chosen to
describe the desired visual appearance of the displayable elements of the product information
by enumerating the available graphical presentation styles.
The presentation resource Schema provides basic graphical capabilities such as text font defini-
tion, Symbol definition, and colour definition.
The visual presentation characteristics described in this part arc often associated with informa-
tion from other generic resource Parts, especiallv with geometric and topological representations
c
xiv
c ISO
(ISO 10303-42). The Appl ication Protocols determine which resource Parts are used together.
Applications which make use of the generic resources in this part provide both the product
information to be visually presented and the semantic meaning of the presentation. Possible
applications include rendered views of product shape, results of scientific visualization, technical
drawings, diagrams, Charts, and graphics for technical publications.
Relation to graphics Standards
The integrated resources specified in this part of ISO 10303 support the visual presentation
of the properties of products. The generation of visual images using data specified by these
integrated resources requires the use of an appropriate display System. This part of ISO 10303
specifies the input data to such Systems, together with the necessary structures and constraints
that relate presentation data to other aspects of product data.
Many display Systems conform to existing ISO Standards for Computer graphics, such as GKS-
and PHIGS/PHIGS PIUS (ISO/IEC 9592). This part of ISO 10303 takes
3D (ISO/IEC 8805)
into account the concepts and terminology of these Standards. Input data specified by this part
of ISO 10303 is therefore intended to be suitable for further processing by displays conforming
to graphics Standards.

data and are exchanged together between Systems with the aim that the receiving System tan
construct one or several pictures of the product information suitable for human perception.
This part specifies the generic resources required to describe the desired visual appearance of
product information in its picture. The actual generation of the picture from the product
infornmation and its presentation data is left to the receiving System. The actual depiction may
deviate from this target because of limitations in the capabilities of graphics Systems.
Product information tan be visualized in two ways, either by realistic, life-like images according
to the rules of projective geometry and light propagation and reflection, or by symbolic presen-
tations that conform with draughting Standards a,nd conventions. This part supports both types
of present ations. The two types of visualization processes require different kinds of graphical
transformations and these may be combined in the Same picture.
The following are within the scope of this part of ISO 10303:
- Association between product data defined by other Parts of ISO 10303 and presentation
dat a;
- Support of graphics functionality in compliance with current ISO graphics Standards;
-
Definition of presentation style attributes for realistic and symbolic visualizations of
geometric and non-geometric displayable elements in the product information;
-
Control of approximation tolerantes for geometric presentation elements;
-
Methods for defining the appearance of characters and Symbols in fonts;
-
Support of externally defined Character fonts and Symbols;
- Image control by a layer mechanism;
- Nesting of presentation areas.
The following are outside the scope of this part of ISO 10303:

-
Definition of product information;
-
Exchange of purely graphical information without any relationship to product informa-
tion;
-
Definition of the contents of Character font and Symbol libraries.
