  • Making Holes and Windows in Surfaces
    The Mathematica journal, 2008
    Co-Authors: Alan Horwitz
    Abstract:

    In this article, we demonstrate makehole, a program which removes points from any Graphics or Graphics3D picture whose coordinates satisfy a stated condition. We also demonstrate transparent and makewindow, programs which make an entire or a specific portion of an opaque surface into a transparent mesh. We use these programs to view the region of integration for a triple integral. This article uses Mathematica 5.2, but with minor modifications all three programs work in Mathematica 6, as well as earlier versions. The makehole program duplicates some of the functionality of the RegionPlot3D command and RegionFunction option of the ParametricPlot3D command in Version 6, while the transparent program behaves like the Plotstyle O None option of the Plot3D command (see Editor’s Note for a demonstration of the Mathematica 6 code).

  • Chapter 6 – Graphics Primitives
    Mathematica Navigator, 2020
    Co-Authors: Heikki Ruskeepää
    Abstract:

    Publisher Summary This chapter provides an overview of graphics primitives. Graphics is a command designed to build plots from graphics primitives. The primitives include line, circle, arrow, text, and rectangle. The styles of the primitives can be adjusted with graphics directives. There are such directives as point size, thickness, dashing, gray level, RGB color, and opacity. Building plots from scratch with Graphics is one use of the primitives and directives. This may also be called graphics programming. These directives can be used in enhancing usual plots with options such as Plotstyle. The importance of the primitives and directives is even clearer considering the fact that all plots in Mathematica are made up of these components. One can construct a plot directly from the primitives and directives, and the primitives and directives can be used to modify plots with options.
