Effects of virtual remodelling in descriptive geometry

摘要

In descriptive and projective geometry, the conceptsof modelling or remodelling cannot be simplistically defined and appliedthrough graphic operations based only on formal results or visualisation. Thediscussion of a scientific result as concerns descriptive drawing has the scopeof obtaining an image or more than one image projected on planes and in space,as they derive from specific and regulated geometric operations and from in–depthreports related to the investigation of the object of study. The graphic–geometricaspect concerns a question that first and foremost is regulated by a methoddefined by the main bi–univocal relation between projection and section and,consequently, by an application of the procedure related to the system ofrepresentation. To draw or represent scientifically signifies penetrating intothe knowledge of an entity or an object, while respecting its intrinsic rules.There can be no scientific basis if the procedure is not preceded and supportedby an acquired and codified methodology. Modelling signifies going back toknowledge, a fundamental condition for representing the entire graphic–geometricprocess that also implies the knowledge itself of the investigated object. Tothe concept of remodelling is also juxtaposed that of virtuality and in thisway it is possible to discuss in scientific terms in order to determine therelationships referring to the investigation carried out on an object in thedual relationship of model: the first understood as technical – scientificstructure acquired also from its history of codification, the second the resultof a process of experience in which the model itself becomes concrete andexplicit in its image projected on planes or in space. The scientific nature ofa program of research and of consequent operations of study cannot be such ifthe graphic and geometric terms are not compatible with all of the steps of amethodology and subsequently of a procedure. This is a question of necessity tounderstand and know through the image, the form and, consequently, the objectacquired through an introspective process determined also by the unification ofthe methods of representation, as well as by the type of investigation that hasallowed us to understand, know, and draw how the object is constituted in itsvarious parts and in its entirety.
