Abstract

This paper proposed a new anti-aliasing algorithm based on delay coloring and dynamic target light effect to solve the problem of aliasing in aerial simulation. Firstly, for the macro static scene, it extracted the edge region of the scene by using the normal information and position information, and smoothed the edge by jitter sampling, and optimized the anti-alia-sing result by using certain multiple of super-sampling. Secondly, on the basis of the previous step, for the dynamic target in the scene, it established the mathematical model of geometric transformation and light effect. The final display effect was determined by calculating the pseudo-distance and the position coordinates of dynamic targets in the virtual scene, so as to solve the problem of aliasing and pixel loss in the real-time motion of dynamic targets. Finally, it verified the algorithm in a flight simulation platform. Experimental results show that the algorithm can solve the problem of aliasing in static scene and dynamic target in aviation simulation, and it is suitable for aviation simulation training.
