We investigate the problem of generating 3D meshes from single free-hand
sketches, aiming at fast 3D modeling for novice users. It can be regarded as a
single-view reconstruction problem, but with unique challenges, brought by the
variation and conciseness of sketches. Ambiguities in poorly-drawn sketches
could make it hard to determine how the sketched object is posed. In this
paper, we address the importance of viewpoint specification for overcoming such
ambiguities, and propose a novel view-aware generation approach. By explicitly
conditioning the generation process on a given viewpoint, our method can
generate plausible shapes automatically with predicted viewpoints, or with
specified viewpoints to help users better express their intentions. Extensive
evaluations on various datasets demonstrate the effectiveness of our view-aware
design in solving sketch ambiguities and improving reconstruction quality.
