Computer Technology Truth One’s Feelings Imitate For Snow Generating And Snowflakes Are Swirling In The Air Roaming

Natural landscape in Snowflakes are swirling in the air scene, you need to take intoaccount the irregular shape snowflakes, no regularity and movement by environmentalfactors such as the impact, which it describes modeling and motion are more difficult. Toimprove the realism of simulated snow scene, particle effects system and the need tointroduce snow particles and wind field generating real-time interaction.Firstly, the fractal method to draw lines and draw three-dimensional snow flake.Previous snow scene snow models are constructed two-dimensional, cannot meet thereality of snowflakes in the wind field simulation of rotating movement, and the use ofthis method can not only ensure snowflake simulation scene rendering speed can meet itsown rotary motion simulation, while changing drawn segments attributes that makedrawing with snowflakes look flash, and enhance the realism of snowflake shapes.Secondly, by reading and analyzing a large number of domestic and foreignreferences summarize the basic principles of particle system, the basic model of theparticle. Then come to the particle system’s general structure, this general structure andsnow particles combined with the actual situation of the snow particles eventually come toeasy control subsystem model, and thus more realistic to achieve natural snowingsnowflakes scattered effects.Finally, the analysis of the process of falling snowflakes in the force, simplifying theforce suffered in no wind condition, we assume that it is only by gravity. By adding a gridof wind farms, we can control the direction and magnitude of the wind to achievereal-time interaction with snow flake. You can simulate more realistic snowflakes in thegravitational field and wind farm movement. This approach not only can be more realisticsimulation of snow sports, and you can easily control the scene.Based on the above design and implementation of a snow scene simulation system,the proposed algorithm is simulated snowflakes and experimental verification in the sceneroaming, rich content of the scene, so that the operator can be used as the first person inthe scene move around to watch.
