| summary |
This article deals with a new idea for generating plane representation figures of three dimensional objects and describes a corresponding computer program. Instead of using the classical perspective rules that govern retinal images as well as common cameras, a different projection method is elaborated based upon the use of a particular kind of curved projection rays instead of the usual straight ones. Curvature of projection lines is made depending on an index variable between zero and one. Meanwhile conical and parallel classical images are obtained for the limit values, compromise images result with intermediate values. Fundamentals, analytical procedure and program for displaying images are presented. Finally, examples are shown and the development possibility of a new type of camera with the property of producing pictures according to different indexes is raised |
