    In this article we propose algorithms that address the two basic problems encountered in generating continuous-tone images by ray tracing: speed and aliasing. We examine previous approaches to the problem and then propose a scheme based on the coherency of an auxiliary data structure imposed on the original object domain. After investigating both simple spatial enumeration and a hybrid octree appr... View full abstract»

    A system of Constructive Solid Geometry (CSG) enables an engineering designer to compose threedimensional shapes by combining simpler ones. Definitions of such objects are represented by tree structures or directed acyclic graphs. Most existing systems convert this representation to a more conventional boundary representation of the solids in order to render pictures from the model. More recently,... View full abstract»

    This article describes a method of representing a solid design procss using a tree structure. This representation supposrts UNDO and REDO operations for regenerating any solid in a previous stage of the design. The implementations of invertible set operations is also given in detail.

  • Special Cinematographic Effects with Virtual Movie Cameras

    Publication Year: 1986, Page(s):43 - 50

    The term "virtual camera" is often used in computer graphics, but it usually represents a mere abstraction for labeling the projection mechanism from 2D to 3D. We believe that a virtual camera should be a software entity that can be manipulated in the same way as cameramen manipulate real cameras. This article presents a model of a virtual movie camera and describes typical effects used by cameram... View full abstract»

    We discuss in this article the need for a minimum suite of raster display routines, the design requirments for such a suite of routines, and the specifications for a package satisfying these design requirements. Finally, we outline our experience with the implementation and use of the resulting package in an educational environment. In the Appendix we give a detailed specification of the actual pa...

  • An Interactive Procedure for Constructing Line and Circle Tangencies

    Cited by:  Papers (2)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (2264 KB)

    This note describes a procedure that enables a designer or draftsperson with limited mathematical training to discover interactively the construction of a wide variety of tangency and intersection problems. Requiring very little code to implement, it supplements the standard tangency constructions available on commercial turnkey computer-aided-design systems with a flexibility unavailable even thr...
