Mapping model SHADOW BALL IN PERSPECTIVE

摘要

Training model display shadows of the ball in the long term is for visual examination and demonstration display of its own and the falling ball shadows on the plane in linear perspective. Based on (1) perpendicular to the utility model fixed plate (2) with clamps (12) for the elastic yarns (13). Due to set the ball (4) on the rack (3) in which (6) is mounted a spherical ring (5) with holes, through which elastic threads, and the introduction of additional interchangeable plates (10) with clamps for elastic threads with a different arrangement of clamps along the curve of the second order (circle, ellipse, parabola, hyperbola), and a telescopic rocker (8) which is fixed at one end thereof in a spherical joint (7) on the base and a clamp (9) on the second end thereof are fixed the elastic yarns is achieved possibility NOSTA visual study and demonstration display in the linear term eigenvectors and falling ball shadows on the image plane position at a different point of view, the 1-yl.
