Abstract
A mathematical support of target layout animation on the image of the shooting range with shielding by nearby objects and without flickering for the optical-electronic shooting simulator'Inhibitor' developed at Institute of mechanics UdmFRC UB RAS and at Computer facilities department of Kalashnikov ISTU jointly with JSC «Kalashnikov» Concern» is described. The tactical and technical task for the implementation of realistic target layout animation is given: support for all exercises from the Shooting Course with emerging-disappearing and moving targets on the surface of the shooting range with local objects that shield them, as well as folds of the area and other targets. Movements should be realistic in speed and angular dimensions of targets, smooth without jerking and correspond to the exercise scenario from the Firing Course: targets up to 2 m/s, armored vehicles up to 4 m/s at an angle of 15-20 from maximum ranges to minimum ones. The animation frequency should be maintained at least 25 frames/s, with the priority of the target layout (at least up to 32 at the same time) over special effects and local objects. The conducted studies of the animated target positioning accuracy with strong reduction in their size at longer ranges to ensure the realism of aiming at such images confirmed compliance with the requirements of TDP (significantly less than 0.3 thousandth range or 1.5 mm). Based on the prospects for further research and development of electronic shooting simulators and thanks to the improvement of computing tools and the development of software graphic libraries, it is necessary to expand the functional capabilities of simulators and reduce the cost, so as to increase competitiveness, for example, due to the realism of the animation of the target environment.
