中文摘要：

结合径向基函数和隐式曲面构造原理,提出了一种保特征的隐式曲面重建算法。应用紧支撑单元产生稀疏的矩阵,降低了计算复杂度,可重建大规模的点云数据。通过几次简单调整支撑域内点的个数,获得保持原特征的重建效果。实验结果证明,算法可以保持原模型的特征。

英文摘要：

According to radical basis function combined with implicit polynomials,a new implicit surface reconstruction algorithm for holding features is presented.The use of compactly supported elements generates a sparse solution space,reducing the computational complexity and making the technique practical for large models.Through a simple adjustment to obtain the number of supported domain points,the reconstruction results can hold the original characteristics.Experimental results show that the algorithm can maintain the characteristics of the original model.
