Research On Visualization Method Of Solar System's Invarable Plane

When studying the dynamic evolution of the solar system,the invarable plane of the solar system is a natural reference plane.Due to the accuracy of the invarable plane and it's basic dynamic significance,the invarable plane provides a permanent natural reference plane.The study of the invarable plane of the solar system is of great significance to the exploration of the space environment.However,the application of invarable planes in computers is relatively small,and it's visualization is an urgent problem to be solved.To intuitively understand invarable plane and accelerate the application of invarable plane in aerospace field,the invarable plane visualization based on OpenGL is completed.Meanwhile,in order to improve the realistic effect of celestial simulation,the existing texture mapping algorithm is studied and improved.The main contents include:(1)An invarable plane visualization method based on angular momentum calculation is proposed.Firstly,under the development platform VS 2017,the starry sky background and celestial bodies are draw by OpenGL.Secondly,using the theory of star position calculation to complete the motion of the solar system and using viewpoint control technology to realize roaming interaction.Finally,the invarable plane of the solar system is visualized based on the angular momentum calculation results.At the same time,the visual simulation and verification of the invarable plane is completed by Blender modeling software.(2)A texture mapping algorithm based on five parameters is proposed to enhance the realistic effect of celestial body simulation.It applied to the simulation of celestial bodies.The results show that this algorithm has an average improvement of25% in terms of visualizations compared with the algorithm based on area or angle.(3)Aiming at the problem of using traditional algorithms for texture mapping will produce large distortion rates,a spherical texture mapping algorithm is improved.Experiments show that this algorithm has a good anti-aliasing effect.(4)Based on the above research,we have completed the visualization system of invarable plane of the solar system,which is used to realize the visualization and interactive operation of invarable plane.
