Abstract : Most surface textures convey useful information about the slant curvature, and depth of the surface, as geometric consequences of perspective projection (primarily foreshortening and scaling). For the visual system to correctly interpret two-dimensional (2D) evidence of foreshortening and differential scaling as suggesting three-dimensional (3D) slant and depth, certain assumptions must hold regarding the regularity or homogeneity of the physical texture as well as its statistical isotropy. Recommendations are given regarding the selection of textures for flight simulation which match the perceptual assumptions and thereby permit 3D percepts.
