Abstract: An interactive graphics system for the mathematical representation of physical models, comprising at least one measuring machine bidirectionally connected to a central unit to which are connected a video screen and a keyboard and including processor means adapted to receive from the measuring machine information on at least initial identification points of the model, to control the automatic detection of information on additional points of the model by means of the same measuring machine, and to process this point information to produce the mathematical representation of the model.

Abstract: An interactive graphics system for modelling physical articles, includes a measurement device connected bi-directionally with a central unit to which a video screen and a keyboard are connected, as well as processing media which are suitable for receiving from the measurement device, at least, data on initial model identification points, and for controlling the automatic collection of addition data regarding the model by means of the same measurement equipment in order to provide such data for processing for use in deriving the model.
