Abstract
<p class="a"><span lang="EN-US">Representation of the wire line shape depending on the wire tension and temperature was considered. A method was developed for constructing a geometric threedimensional line model and synthesis of its images used in the visualization system of the simulator complex. Solution of the problem of synthesis and visualization of extended objects is hard and computationally complex because of the high detail of such objects and strong unevenness of their projection. The method makes it possible to obtain a set of triangles describing the line in real time using known sagging parameters and distance between the suspension points. To do this, one does not need the line scanning in contrast to the used methods of lidar scanning or photogrammetry. Sagging of the line wires can vary in real time depending on external conditions. The resulting set does not contain explicitly visible kinks or artifacts for any position of the observer within the simulated section of the line.</span></p><p class="a"><span lang="EN-US">The method minimizes aliasing artifacts on the wire line elements remote from the observer, automatic texturing and calculation of normals to the line surface which enables correct calculation of illumination for any line fragment when synthesizing images in the visualization system. The speed of the method was evaluated, its implementation within the visualization system has shown a functioning speed enough for realtime operation and examples of synthesized line images were given.</span></p><p class="a"><span lang="EN-US">The required computational resources for synthesis of the line image were minimized by using a flexible system of detail levels which has enabled use of cheaper hardware for constructing visualization systems and resulted in reduction of the price of the simulator complex in general.</span></p>
