Migration of GKS/GKS‐3D and PHIGS Discussed under the View of the Computer Graphics Reference Model

The Migration Problem of GKS‐3D and PHIGS is discussed in this report under the view of the graphics reference model's description technique: the component and framework concept. Therefore the components of GKS‐3D and PHIGS are defined. The common and different concepts are indicated and the mapping from PHIGS to GKS‐3D and from GKS‐3D to PHIGS is done. This mapping is performed only on the components which have been proved as a description technique suited for such purposes. The migration has two different aspects. One is the theoretical approach to prove that such a migration is possible. The other one is more practical. It gives guide‐lines for the use of PHIGS and GKS‐3D and shows under which circumstances both can be used together.
