About This Item
ISO/IEC 9593-4:1991 defines the C language binding for Programmer’s Hierarchical Interactive Graphics System (PHIGS), helping developers and technical teams align software interfaces with a recognized graphics programming model. As part of the ISO/IEC 9593 series, it is relevant when engineering documentation, procurement review, or technical validation depends on consistent application programming behavior across systems. For organizations managing legacy graphics software or interoperability checks, ISO/IEC 9593-4:1991 can serve as a focused compliance reference.
Purpose of ISO/IEC 9593-4:1991
The purpose of ISO/IEC 9593-4:1991 is to specify how PHIGS is accessed from the C programming language, supporting consistent implementation and documented evaluation of graphics-related software interfaces. It is intended to help programmers, reviewers, and test teams confirm that a C-based application follows the expected binding conventions within the PHIGS framework. In practice, that makes it useful for technical review, system integration planning, and operational consistency in software development workflows.
Compliance applications of ISO/IEC 9593-4:1991
Organizations may use ISO/IEC 9593-4:1991 during product evaluation, software conformity assessment, and laboratory evaluation of graphics applications that rely on PHIGS and C language integration. It can also support procurement decisions where compatibility with a defined programming interface is required, particularly in environments that maintain older engineering or visualization systems. For teams preparing technical documentation, the reference may help structure verification activities and reduce ambiguity during implementation checks.
Benefits of ISO/IEC 9593-4:1991
This document supports clearer engineering documentation and more repeatable testing workflows by defining a specific language binding for PHIGS in C. That can reduce integration risk, improve technical validation, and make it easier to compare implementations during conformity assessment. For procurement and compliance workflows, it offers a focused reference point when evaluating whether a software product or development platform aligns with the expected interface behavior. It may also help preserve consistency across long-lived systems and legacy code bases.
