本文介绍了一项研究的结果，在该研究中，艺术家的线条画旨在传达特定的3D形状。该研究的设计使图纸可以与3D模型的渲染图像配准。支持对艺术家的线的位置与其他艺术家的线的位置、与当前计算机图形线定义以及与3D表面的潜在差异属性的相关程度的分析。在这项研究中，艺术家绘制的线条在很大程度上相互重叠（75%的线条与另一条线的距离在1 mm以内），特别是沿着物体的遮挡轮廓。大多数不与轮廓重叠的线与图像强度的大梯度重叠，并且与计算机图形学中最近的线绘制算法所做的预测强烈相关。14%的人没有很好地描述本研究中考虑的任何当地属性。我们的工作成果是一个公开的对齐图纸数据集，基于3D模型的局部属性分析线条在数据集中的位置，以及预测艺术家将在新场景中绘制线条的算法。
This paper presents the results of a study in which artists made line drawings intended to convey specific 3D shapes. The study was designed so that drawings Could be registered with rendered images of 3D models. supporting an analysis of how well the locations of the artists' lines correlate with other artists', with current computer graphics line definitions, and with the underlying differential properties of the 3D surface. Lines drawn by artists in this study largely overlapped one another (75% are within 1 mm of another line), particularly along the occluding contours of the object. Most lines that do not overlap contours overlap large gradients of the image intensity, and correlate strongly with predictions made by recent line drawing algorithms in computer graphics. 14% were not well described by any of the local properties considered in this study. The result of our work is a publicly available data set of aligned drawings, an analysis of where lines appear in that data set based on local properties of 3D models, and algorithms to predict where artists will draw lines for new scenes.
