摘要： 研究了点采样模型的多样性编辑与绘制，将模型分解成不同的部分，将各部分按照层次关系组织，作为多样性编辑的基础。对模型各部分点元的颜色、几何特征、材质等属性进行编辑，构造层次多样性点模型。通过对层次多样性点模型进行实时处理，实现点模型的多样性绘制。实验表明，该方法能够产生并绘制复杂多变的点模型，且压缩比高。该方法可应用于网络游戏、战场视景仿真、数字城市、电影制作等领域。

Abstract: A point-sampled model is divided into some parts, and these parts are organized in hierarchy. The model acts as base model of variety editing. Through editing color, geometry, material attributes of point primitives of every part, a variety hierarchy model is constructed. Through real-time operating the variety point model, variety rendering of dynamic scenes is implemented. Experiments show the method can create and render variety point models, and the data compression ratio is high. The method can be used in the fields of network games, war field environments simulation, urban environments simulation etc.

Key words: Point based modeling and rendering, Point primitive, Variety
