New visual representation software from Transas, named Seagull_Vis 4000, represents the synthetic environment with much higher level of realism. It includes a number of advanced effects designed specifically for marine applications and developed to further improve the efficiency of simulator-based training. This new system incorporates a high quality three-dimensional sea model with dynamic bump- mapping surface texturing. The simulated sea surface realistically reflects sky, clouds, sun, moon and stars, while the natural light sources, such as the sun and moon, are reflected with their lighting paths.
The color palette of the water surface, as well as, a wide range of other visual presentation parameters can be pre-set or dynamically changed from the instructor workstation. The simulated star globe is based on a true mathematical model of stars and planetsí positioning and angle size, depends on the observerís geographical position, time, date; and changes dynamically during the course of an exercise. In Seagull_Vis 4000, the visibility of space objects is naturally influenced by pre-set general meteorological visibility conditions, such as fog, rain, and snow; as well as the pre-set cloud density. Atmospheric precipitation now includes realistic 3D rain and snow models with pre-set or dynamically changed speed and density.
