VISUALIZATION OF A LIFEBOAT MOTION DURING LOWERING ALONG SHIP’S SIDE

Abstract

This paper presents description of a computer program for motion visualization of a lifeboat lowered along ship’s side. The program is a post-processor which reads results of numerical calculations of simulated objects’ motions. The data is used to create scene composed of 3D surfaces to visualize mutual spatial positions of a lifeboat, ship’s side and water waving surface. Since the numerical data contain description of a simulation as a function of time it is possible to screen a static scene showing the simulated objects in an arbitrary instance of time. The program can also reproduce a sequence of scenes in the form of animation and control its speed. The static mode allows to view an arbitrary crosssection of the scene, rotate and enlarge specific details and make the image more realistic by hiding invisible lines or shading. The application of the program is aimed at making it possible to assess and analyze numerical calculation results in advance of their experimental verification.
