(FR) DISPOSITIF DE DESSIN TRIDIMENSIONNEL
Abstract:
(EN) A three-dimensional drawing device comprising a transparent hollow globe (12), a powder material (86) disposed within the globe which adheres to the inner surface of the globe, a scribe (44) disposed within the globe which can be used to draw upon the inner surface of the globe by scraping off the powder material, and controls (14, 16) for manipulating the scribe. The device can be used to form three-dimensional sketches and is primarily intended for use as a teaching aid and toy.
