Abstract

One of the most difficult problems in the marine trainer development is visualization of the moving boat. This problem consists of two separate subtasks: • development of the realistic physical model of a moving boat • modeling of various phenomena accompanying boat movement such as water foam arising in the stern part of the boat The significance of the realistic physical model of the boat movement is intuitively clear while the importance of the second problem requires some explanation. The boat movements along water surface looks quite unnaturally without water foam even though it is based on the exact physical model. Therefore the problem of visualization of water effects accompanying boat movement is as important as boat movement modeling itself. The article presents an algorithmic approach to a problem of visualization of water foam arising in the stern part of a boat. The foam is not a conventional object for 3D graphics technology. As most other natural phenomena such as fire smoke, etc. it could be hardly represented with a bounding surface, as it is usual for solid shapes. The frame rate in marine trainers should be greater then 20 frames per second so strong time restrictions should be applied to the visualization algorithms. Due to this restrictions it is impossible to use a straightforward physical processes modeling. Instead the new approaches are needed aimed on visual similarity rather then physical accuracy.
