For centuries, the use of a sketch book as an experimental space and as a spontaneous, reference resource has been widespread amongst artists and designers. This is evident from the wealth of ideas expressed in the notebooks of Leonardo da Vinci [1] and in the accounts of Delacroix who was said to have loosened up his hand by drawing from the imagination, producing a variety of sketches that provided him with ideas to be used at a later date.By sketching, a designer releases a fluid stream of visual experiences, not all of which can mentally be retained. However, single sketches give only single view point representations of objects. It is therefore necessary to translate "…the back of-the-envelope stuff…" [2] into a three dimensional scaled model in order to fully realize a form. Much creativity and enthusiasm is dissipated during this transformation. Similarly, the precise preparation needed for input to a standard CAD system for a computer generated models is not consistent with the excitement of creative exploration expressed by Henry Moore. "The act of converting an idea into line and other marks on paper often excites the mind and frees the imagination encouraging the flow of creative thought." [2]The desire to observe and create directly in a 3D space, capturing the essence of the sketch and receiving instantaneous three dimensional feedback, has inspired the development of this project.
