为了对3维复杂树木场景进行真实感强的建模和动画制作,在"桃林"和"毛白杨"两项场景建模及动画制作研究工作的基础上,探讨了一种适合3维复杂树木场景建模及动画制作的优化方法.该方法首先把复杂树木场景,根据对视觉影响大小的不同分解为近景和远景;然后在建模和动画制作过程中,采用不同的技术进行处理,其中,对近景树木可基于粒子系统进行建模和动画制作,而对远景则根据需要分别采用树木层叠环形柱状背景,以及约束平面贴图的方法进行建模和动画制作.由此建立的复杂树木场景,不仅近景生动逼真,而且远景也能获得理想的视觉效果,从而实现了简化模型与视觉效果之间的平衡.

This paper analyzes the application of an optimized method in the modeling and animation of 3D complex forestry scenarios of peach and Chinese white poplar.The paper divides the forestry scenarios into close views and distant views respectively according to different visual impacts,and applies different modeling and animation procedures.The particle system is employed in the close views while the methods of multi-layer circle cylinder baekground and the plane-mapping constrains model are adopted for the distant views.The complex 3D forestry scenarios created have vivid close views and excellent visual effects in distant views.The method well accomplishes the simplification of models and the optimization of visual effects.
