基于手绘的3D概念模型建模

摘要

以笔画为基础,使用变分隐式曲面方法,构造形式自由的3D模型。文中描述了建模的具体步骤,并讨论了每一步骤中需要注意的问题,设计出了可以进行自由绘制的程序。程序运行结果表明,使用变分隐式曲面绘制的模型具有光滑、封闭的特性,而且可以方便地进行融合和其他后续操作。%This article presents a 3D modeling approach that uses the varational implicit surface as a geometric representation for free-form shapes.The modeling processes are described in detail and the problems that deserve special attention in each step are pointed out.A robust program for sketching free-form silhouette is designed.Program running tests show that the varational implicit surface modeling is smooth and closed,and convenient for fusion and other follow-up operations.
