Summary
The Computer Graphics Standard GKS does not support complex segment structuring and editing facilities. With the dissemination of very powerful workstations and devices, there is a need for GKS-extensions with multilevel segment structures and editable objects. One approach to a specification of such a system is PHIGS, the Programmer’s Hierarchical Interactive Graphics Standard. In the following we will present an alternative to PHIGS called GEO (Graphics System with Editable Objects). GEO is upwardly compatible to GKS in a very natural way. In addition, naming of graphics objects can be provided in terms of application oriented aspects.
