Visualizing quaternion rotation
Hart J. (ed), Francis G., Kauffman L. ACM Transactions on Graphics (TOG) 13(3): 256-276, 1994. Type: Article
The authors discuss the fundamentals of quaternions, their use in computer graphics for specifying rotations, and the mathematical modeling of a quaternion demonstrator. Section 2 begins with a short review of definitions and other mat...

Refinement methods for geometric bounds in constructive solid geometry
Cameron S., Yap C. ACM Transactions on Graphics (TOG) 11(1): 12-39, 1992. Type: Article
The idea of using boxes to bound complex shapes and prune costly geometric computations has been used in several fields for over a decade (see my work with N. Badler [1]). Within solid modeling, bounding “has passed into the ...

Hierarchical Data Structures and Algorithms for Computer Graphics. Part I.
Samet H., Webber R. IEEE Computer Graphics and Applications 8(3): 48-68, 1988. Type: Article
The authors first draw a distinction between the data formats of raster graphics (2-dimensional arrays) and vector graphics (linked lists of line segments). The two models in turn give rise to a discussion of the well-known image space...

Geometrical transformations on pictures represented by leafcodes
van Lierop M. Computer Vision, Graphics, and Image Processing 33(1): 81-98, 1986. Type: Article
An algorithm is described for generating nonsingular affine transformations of black and white quadtrees represented as linear trees. The linear representation used, called the leafcode, is an ordered sequence of encoded BLACK l...
