中文摘要: 由已有模型构造新的模型是数字娱乐领域的重要造型方法,提出了一种基于RBF(径向基函数)的点模型布尔运算方法。该方法首先将输入点模型进行空间八叉树划分,然后采用RBF将点模型隐式化生成隐函数表示的符号距离场,最后通过隐式曲面的布尔运算方法剔除多余的点,得到需要的新点模型。对点模型进行空间八叉树划分加速了点模型的RBF隐式化过程。该方法可由多个简单的点模型快速构造出复杂的点模型。

Abstract:To construct a new model from the existing models is an important modeling method in digital enter- tainment. Boolean operation method for point models based on RBF (Radial Basis Function) is proposed in this paper. Firstly, it divides the input point models by octree. Then it transforms the models to implicit function represented signed distance field. Finally through the implicit surface Boolean operation method to exclude the extra point, a wanted new point model is obtained. The process of RBF implicitization for point model is accelerated by space octree division. A complex model can be constructed form several simple point models with this method.
