Part 46:
Integrated generic resource:
Visual presentation
This document specifies the integrated generic resource constructs for
visual presentation.
Presentation data as provided in this part of ISO 10303 are combined with product data and are exchanged
together between systems with the aim that the receiving system can construct one or several
pictures of the product information suitable for human perception.
This part of ISO 10303 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 information and its presentation data is left to the receiving system.
The actual depiction can deviate from this target because of limitations in the capabilities of graphics systems.
Product information can 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 presentations that conform with
draughting standards and conventions.
This part of ISO 10303 supports both types of presentations.
The two types of visualization processes require different kinds of graphical transformations and these can be combined
in the same picture.
The following are within the scope of this document:
- association between product data defined by other parts of ISO 10303 and presentation data;
- 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 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;
- external image association to tessellated geometry;
- association of colour information with vertices of tessellated geometry.
The following are outside the scope of this document:
- definition of product information;
- exchange of purely graphical information without any relationship to product information;
- definition of the contents of character font and symbol libraries.
