- Abstract
- In describing graphics description with electronic tools, solid modelling is the application in which several techniques (2 and 3 dimensional CAD, image processing, animation) act together. Solid modelling is therefore a very important topic, both from methodological and practical aspects. This paper deals with the process of generating a digital model, and discusses the following statements: A. The analysis of archaeological evidence is based on the description of a real (and therefore continuous) and complex space through the identification and coding of its components; this activity is then undertaken through a modelling process. The models used for the analysis must have at least the basic requirements for the electronic description of the objects: a quantitative requirement – to be able to describe numerically and analytically the objects in space (vector data); a qualitative requirement – to able to describe their physical/optical features (visual/raster data); a synthesis requirement – to be able to consider the codes and the rules of union of the components (text and topological data). B. The data collected have to be acquired, worked out and edited coherently with the need of their subsequent use within the software devoted to the virtual elaboration of the shape (i.e. the sample rate must be the same during the acquisition of visual and numerical data ). C. The electronic reassembly of the shape must take into consideration all the different levels used in the coding, in order to have both a topographic and topological description of the object.
