Abstract
Two
dimensional ( 2D drawings of impossible figure s are typified by the lithographs of the Dutch artist M.C. Escher , such
as Waterfall Belvedere and Ascending and Descending Impossible figure s are mental images of solid object s. I n
other words, a three dimensional ( 3D figure that is visualized intuitively from a 2D drawing of an impossible figure ca n not
be constructed in 3D space. Thus , in reality , a 3D model of an impossible figure has an unexpectedly disconnect ed or
deform ed structure, but the 3D figure corresponds to the 2D figure from a specific viewpoint, although not from other
viewpoints. Methods for representing 3D model s of impossible figure s have been studied in virtual space The shape s and
structure s of impossible object have also been studied in real space , but the effects of physical illumination by light and
appropriate texture s have not been considered. Thus, t h is paper describes the mimetic surface color and texture adjustment
( method for producing naturally shaded and appropriate ly textured 3D impossible object s under physical light
sources. And some creative work s applying this method are shown , including a new structure with impossible motion.
