本文介绍了一项研究结果，其中艺术家制作了旨在传达特定 3D 形状的线条图。这项研究的目的是让绘图可以与 3D 模型的渲染图像进行配准。支持分析艺术家的线条位置与其他艺术家的线条位置、当前计算机图形线条定义以及 3D 表面的底层微分属性的关联程度。在这项研究中，艺术家绘制的线条大部分相互重叠（75% 与另一条线的距离在 1 毫米以内），特别是沿着物体的遮挡轮廓。大多数不与轮廓重叠的线条与图像强度的大梯度重叠，并且与计算机图形学中最新线条绘制算法所做的预测密切相关。本研究中考虑的任何当地属性都没有很好地描述 14%。我们的工作成果是一个公开的对齐绘图数据集，根据 3D 模型的局部属性分析该数据集中线条出现的位置，以及预测艺术家将为新场景绘制线条的位置的算法。
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.
