Krive jajastog oblika u Nacrtnoj geometriji

Abstract

Tema ovog rada su krive koje imaju oblik jajeta, a koje se susreću u različitim oblastima Nacrtne geometrije. Načinjen je pokušaj da se ove krive opišu i svrstaju u nekoliko osnovnih tipova, kroz par primera sa objašnjenjima nastanka i načinima konstruktivne obrade. Sam rad nema ambiciju da pokrije sve moguće slučajeve, već daje osnovne karakteristike nekih najtipičnijih. Svrha ovog rada je, kako u pomoći edukaciji studenata i svih kojima je ova tema interesantna, tako i kao moguća osnova za dalja istraživanja.

The subject of this paper are the curves which have shape of hen's egg, and which can be found in various fields of Descriptive Geometry. The paper attempts to describe and classify some of them in several elementary types, through a few examples with explanations of origin and methods of constructive procedures. The paper itself has no ambition to elaborate all the possible cases of the egg shaped curves, but gives the main characteristics of some the most typical. The purpose of this paper is not only the education of students an to all who may find it interesting, but as well as the foundation for the further explorations.
