DELPHI FMX: 3D modeling-simulation activities

Abstract

This paper describes the main coordinate transformations upon which the design of 3D scenes on a 2D plane (a computer screen) is based. We provide examples of projecting 3D geometric figures onto the computer screen using Pascal programming code. For the design of 3D scenes of any nature, with textures and lighting effects, the use of the Delphi FMX programming environment is recommended, which incorporates 3D graphics components implemented on the OpenGL graphics engine. Based on the examples detailed in this paper, users can perform interactive 3D modelling/simulation activities with a high-quality graphical interface and concise programming code.
