The Polygon Fill style PATTERN and HATCH, which are quite successful in 2D graphics standards as GKS 1 and CGI 2 have proved to be less suitable for 3D graphics standards as GKS‐3D 3 and PHIGS 4 . However, the emerging standard PHIGS PLUS 5 offers a unique chance to successfully employ these Interior Styles (under another name and in a slightly different form), because PHIGS PLUS supports a.o. topologically rectangular parametric surfaces In this article it is shown how these Interior Styles could be efficiently applied to curved surfaces in PHIGS PLUS. In addition, the possible interaction between the tessellation method and the patterning is shown.
