A Very Simple Approach for 3-D to 2-D Mapping

Abstract. Many times we need to plot 3-D functions e.g., in many,scientific experiments. To plot this 3-D functions on 2-D screen it requires some,kind of mapping. Though OpenGL, DirectX etc 3-D rendering libraries have made this job very simple, still these libraries come,with many,complex,pre-operations that are simply not intended, also to integrate these libraries with any kind of system is often a tough trial. This article presents a very simple method,of mapping from 3-D to 2-D, that is free from any complex pre-operation, also it will work with any graphics system where we have some primitive 2-D graphics function. Also we discuss the inverse transform and how to do basic computer,graphics transformations using our coordinate mapping,system. 76,S. Dey, A. Abraham, S. Sanyal
