Flow Field Mapping Optimization Method Of Particle System Based On Map Load

With the in-depth study of particle system theory,the application of particle system to simulate dynamic ambiguity has been widely developed.In many related applications,the dynamic visualization of ocean flow field based on particle system is one of the most important applications.It uses the dynamic,fuzzy and random characteristics of particle system to visually express the flow field information and movement trend.However,for a long time,the research and Discussion on the dynamic visualization expression of ocean flow field based on particle systems have focused on the management of massive particles and the improvement of system efficiency.There are still significant problems and shortcomings in the optimization of graphical expression.In this paper,an optimization method of dynamic mapping of ocean flow field based on particle system is proposed from the point of view of improving the expression effect of dynamic mapping.Aiming at the phenomenon of dispersion and aggregation in the continuous movement of particles,this paper chooses the optimal initial layout strategy of particles through the improved uniformity evaluation method,which effectively improves the uniformity of initial distribution of particles;calculates the particle influence region of the whole dynamic map by setting the particle influence function,and adjusts the life cycle of particles according to the level of the influence region.Effective control of particle uniformity in dynamic maps.Ensure that the particle distribution in the dynamic map is always in a uniform state.Aiming at the situation of particle density after scale change of electronic map,this paper designs and implements the software of particle system suitable load survey,and obtains the suitable load range of particle system through investigation;adjusts the number of particles in the map after scale change according to the suitable load range obtained by statistics,so as to ensure that the load of particles in the map is always appropriate.Within the range of load.Finally,this paper uses Leaflet Map Development Platform to implement and validate the above methods,and evaluates the cartographic effect by questionnaire.Experiments show that the dynamic mapping of ocean flow field based on particle system is effective and achieves the goal of optimizing the mapping effect.
