Mathematical aspects of a graphical programming language and its implementationChan, Bon-boon January 1976 (has links)
This thesis describes the improvements in the mathematical aspects of the high-level programming language for interactive graphics (LIG). Improvement possibilities were investigated in three
areas: dependence on the order of transformations, arithmetic expressions
appearing in LIG statements, and the implementation to allow the programming of graphical functions. The method of implementation
of the proposed improvements is also discussed. / Applied Science, Faculty of / Electrical and Computer Engineering, Department of / Graduate

Concepts for a high level programming language for regional computer graphicsLiu, Bobby Hin Wah January 1979 (has links)
Researchers developing high-level graphics languages have, according to the literature, focused their attention towards line-drawing graphics. Little effort has been devoted to systematic investigations
of languages that handle graphical data representing line-drawings as well as solid areas. The latter type of graphical data is usually represented hy outlines, and solid area properties are visualized
by hatching or filling techniques. A study of the literature on programming languages leads to the conclusion that graphical data should be treated as a data type.
Based on the concept of treating graphical data as a data type in its own right, the mathematical and conceptual aspects of this type of data are investigated and established. Much scattered information, such as the representation of regions, has been unified using formal descriptions. Hatching, one of the many ways of achieving external representation of regions, is also investigated. A hatching algorithm is proposed and implemented that envelops the good features of others, and establishes a framework for hatching algorithms. Its implementation achieves the expected tasks. A proposal for a graphics language demonstrates
the usefulness and feasibility of this type of graphics. Some of its features have been implemented. Finally, a fairly complete bibliography serves as a gateway for further research in this area. / Applied Science, Faculty of / Electrical and Computer Engineering, Department of / Unknown

Interactive least squares surface fittingSamsom, Anthony Harm January 1980 (has links)
This thesis is concerned with the design and implementation of a surface fitting package in an interactive graphics environment. Surface fitting techniques are used to generate a smooth looking, easy to evaluate, bivariate function given a set of data points on some domain in the plane, and are thus useful for a variety of applications. We consider the implementation of a surface fitting technique using weighted least squares with tensor products of B-splines on regular data grids (i.e. the position of the data points can be represented as the cross product of two vectors). While somewhat more restrictive than other surface fitting methods, this technique, when applicable, is extremely efficient.
Knot placement and weight placement are discussed as methods of adapting the spline surface to rapidly varying regions on the domain. A disadvantage of the original method used to solve for the coefficients of the spline surface is that the domain of the function to be approximated must be rectangular. An algorithm to extend the surface fitting method to non-rectangular domains, thus removing this restriction, is presented. An interactive surface fitting package is provided, which allows a user to fit a spline surface to a set of data points on a regular grid. This provides a powerful tool which may be used to effectively modify the spline surface and indicate the accuracy of the approximation. / Science, Faculty of / Computer Science, Department of / Graduate
