Perceiving perpendicular and parallel contours in the frontoparallel plane
2019, Vision ResearchCitation Excerpt :A perpendicular junction in a 3D scene can be projected to a junction with any angle in the 2D image, but this depends on the orientation of the junction in the scene. It has been shown that the perception of a 3D shape from a 2D contour drawing is biased to make the 3D shape have perpendicular junctions (Erkelens, 2015), and to make the faces of the 3D shape form perpendicular corners (Perkins, 1972, 1976; Sugihara, 1997, 2005, 2014b, 2014c; Griffiths & Zaidi, 2000). Note that in this study, we did not distinguish the perception of contours in a 2D retinal image from the perception of contours on the frontoparallel plane in a 3D scene.
Design of solids for antigravity motion illusion
2014, Computational Geometry: Theory and ApplicationsCitation Excerpt :This way, the system of (5) and (6) helps us to construct actual solids that look impossible. Many other examples of such “impossible objects” can be found in [13]. It has been known that the endless loop of stairs can be constructed if we use a discontinuous structure, which looks connected when we see it from a special vantage viewpoint.
