TLDR
In this paper, an algorithm for clipping and capping polyhedrons and a display system for three-dimensional finite element math models to facilitate viewing internal surfaces in the form of continuous tone computer generated color images.Abstract:
This paper describes an algorithm for clipping and capping polyhedrons and a display system for three-dimensional finite element math models to facilitate viewing internal surfaces in the form of continuous tone computer generated color images. A plane is passed through the model with the result that the elements (or portions thereof) on one side of the plane may be eliminated. A new grid is generated for the cutting plane to include the prediction of such quantities as displacements, stresses, and temperatures. The Cutting plane is colored and/or warped to indicate the variation of selected scalar functions.read more

A subdivision algorithm for computer display of curved surfaces.
TL;DR: A method for producing computer shaded pictures of curved surfaces using three-dimensional curved patches, which can be 'mapped' onto patches thus providing a means for putting texture on computer-generated pictures.

Reentrant polygon clipping
TL;DR: A new family of clipping algorithms is described, able to clip polygons against irregular convex plane-faced volumes in three dimensions, removing the parts of the polygon which lie outside the volume.
Illumination for computer-generated images.
TL;DR: In this paper, a new model for the shading of computer-generated images of objects in general and polygonally described free-form curved surfaces in particular is described, where the shading function is determined by a linear interpolation of the curvature of the surface.
