论文摘要
我们通过从看不见的观点提供视觉脚手架来提出一个用于剪贴画设计的辅助系统。受艺术家的创作过程的启发，我们的系统通过首先合成输入剪贴画的参考3D形状并从所需的角度构造视觉脚手架。构建此视觉脚手架的关键挑战是生成一个参考3DShape，该参考将用户的期望与对象大小和定位相匹配，同时保留输入剪贴画的几何样式。为了应对这一挑战，我们提出了一种用户辅助曲线挤出方法，以获取参考3D形状。我们将综合参考3D形状具有一致的样式，以一致的方式进入视觉脚手架。通过遵循生成的视觉脚手架，用户可以通过所需的观点有效地设计剪贴画。由直观的用户界面和我们生成的视觉脚手架进行的用户研究表明，用户能够从不同的角度设计剪贴画，同时保留原始几何样式而不会失去其原始形状。
We present an assistive system for clipart design by providing visual scaffolds from the unseen viewpoints. Inspired by the artists' creation process, our system constructs the visual scaffold by first synthesizing the reference 3D shape of the input clipart and rendering it from the desired viewpoint. The critical challenge of constructing this visual scaffold is to generate a reference 3Dshape that matches the user's expectation in terms of object sizing and positioning while preserving the geometric style of the input clipart. To address this challenge, we propose a user-assisted curve extrusion method to obtain the reference 3D shape.We render the synthesized reference 3D shape with consistent style into the visual scaffold. By following the generated visual scaffold, the users can efficiently design clipart with their desired viewpoints. The user study conducted by an intuitive user interface and our generated visual scaffold suggests that the users are able to design clipart from different viewpoints while preserving the original geometric style without losing its original shape.
