Geometria descrittiva - Volume I - Metodi e costruzioni

Descriptive geometry is the science that studies the geometric shapes of space using their models. Unlike analytic geometry and differential geometry, which use symbolic languages, descriptive geometry uses a visual language and this is the reason why it is an essential tool in engineering projects, as well as in architectural and design projects. Up until only a few years ago, descriptive geometry was carried out exclusively hand drawing on paper, in two dimensions; nowadays it uses the computer, too, which offers the possibility to draw in space and with a much better accuracy of representation. This book proposes the ancient science of Monge in a renewed form: besides the methods codified by the tradition, we will deal with the methods that nowadays are used in the digital modelling applications, namely the mathematical representation and the polygonal representation. These same methods are then applied to the constructions and to the problems typical to descriptive geometry. The reader will be guided towards the solution through procedures that itemize, step by step, the operations to be carried out and, in many cases, the commands to be used
