2D Objects

Part of the Springer Tracts in Mechanical Engineering book series (STME)


Geometric elements are categorized as points, lines, surfaces, and solids. Surfaces and solids also have many subcategories. Points, lines, circles, and arbitrary curves are the basic 2D geometric primitives, or generators, from which other, more complex geometric objects can be derived or algorithmically produced. For example, by taking a straight line and moving it through a circular path lying in a plane normal to the line, while keeping the line normal to the plane, one can create a cylinder. This chapter defines, illustrates, and describes how to create points, lines, circles, polygons, polygonals, and arbitrary curves in the plane. The concept of rigid body in the plane and its properties is given due attention.
