Specifies the integrated resources for the visualization of displayable product information. This information is combined with product data such that a receiving system can construct one or several pictures of the product information suitable for human perception. Annexes A and C are contained in a diskette which accompanies this Standard. It is identical with and has been reproduced from ISO 10303-46:1994.

Scope

This part of ISO 10303 specifies the integrated resources for the visualization of displayable product information. Presentation data as provided in this part 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 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 may 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 supports both types of presentations. 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 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.
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 information;
– Definition of the contents of character font and symbol libraries.
