摘要

在本文中,我们阐述了一种通过绘制稀疏的2D笔画来交互生成具有丰富细节的3D模型的新方法。我们的新方法是泊松矢量图(PVG)的自然扩展。我们设计的新算法与其他现有的基于草图的设计系统有三个独特的特点:(1)一种新颖的基于泊松方程的草图隐喻来创建自由曲面,简单、直观、无歧义;(2)方便灵活的用户界面,用户可以通过简单的草图输入,为表面添加丰富的细节;(3)使用稀疏笔画快速创建模型,使新手用户能够享受我们系统的实用程序来创建预期的3D模型。我们通过一个大型的交互式草图示例库验证了所提出的方法。我们的实验和生产结果证实,我们的新方法是一种简单而有效的设计工具,可以通过简单直观的2D草图输入来建模自由形状。•计算方法→基于草图的建模;

RegionSketch: Interactive and Rapid Creation of 3D Models with Rich Details
In this paper, we articulate a new approach to interactive generation of 3D models with rich details by way of sketching sparse 2D strokes. Our novel method is a natural extension of Poisson vector graphics (PVG). We design new algorithms that distinguish themselves from other existing sketch-based design systems with three unique features: (1) A novel sketch metaphor to create freeform surface based on Poisson’s equation, which is simple, intuitive, and free of ambiguity; (2) Convenient and flexible user interface that affords the user to add rich details to the surface with simple sketch input; and (3) Rapid model creation with sparse strokes, which enables novice users to enjoy the utilities of our system to create expected 3D models. We validate the proposed method through a large repository of interactively sketched examples. Our experiments and produced results confirm that our new method is a simple yet efficient design tool for modeling free-form shapes with simple and intuitive 2D sketches input.
