3D film viewer development and trial

Abstract

Abstract. 3D film viewer is a kind of instrument that can display flat models that can display three-dimensional models. Its simple structure, clever design, and small size are suitable for large and small-format color or black-and-white flat pictures. You can view three-dimensional pictures consisting of perspective or axonometric measurements on the H surface, V surface, and positive axonometric screen. Observed stereo models can be measured directly with a transparent ruler or indirectly with a divider. If you swap the left and right pictures, you can see the symmetry of the three-dimensional model. If you rotate the picture by 180°, you can see the opposite side of the object. The 3D picture viewer has a wide range of uses in teaching, scientific research, production, medical treatment, surveying and mapping, urban and rural general planning, and military affairs. In particular, 3D viewers are used in place of expensive teaching models, building sand tables, product displays, etc. There will be major breakthroughs, which can save a lot of raw materials and storage and transportation costs, resulting in great economic and social benefits.
