Reconstructing 3D shape from 2D sketches has long been an open problem
because the sketches only provide very sparse and ambiguous information. In
this paper, we use an encoder/decoder architecture for the sketch to mesh
translation. When integrated into a user interface that provides camera
parameters for the sketches, this enables us to leverage its latent
parametrization to represent and refine a 3D mesh so that its projections match
the external contours outlined in the sketch. We will show that this approach
is easy to deploy, robust to style changes, and effective. Furthermore, it can
be used for shape refinement given only single pen strokes. We compare our
approach to state-of-the-art methods on sketches -- both hand-drawn and
synthesized -- and demonstrate that we outperform them.

本文提出一种基于编码器 / 解码器架构利用用户界面提供的相机参数对手绘或合成草图进行转换，将草图转化成三维网格并进行图形重塑的方法，并表明该方法易于部署，对样式变化具有鲁棒性和高效性，且具备单笔画进行形状精细化的能力。和目前最先进的方法相比，我们表现更好。
