<!-- Previous ray-based neural 3D shape representations show rapid inferences in diverse scenarios, but the learned structures are inferior due to the lack of
multi-view geometry consistency. Our RayDF addresses the limitation and learns to efficiently and accurately represent continuous 3D shapes.
It is illustrated above by comparing the reconstruction results along smoothed camera paths from our method and previous approach. -->

In this paper, we study the problem of continuous 3D shape representations. The majority of existing successful methods are coordinate-based implicit neural representations. However, they are inefficient to render novel views or recover explicit surface points. A few works start to formulate 3D shapes as <b>ray-based</b> neural functions, but the learned structures are inferior due to the lack of <b>multi-view geometry consistency</b>.<br>
</p>
<p>
To tackle these challenges, we propose a new framework called <i>RayDF</i>. It consists of three major components: 1) the simple <b>ray-surface distance field</b>, 2) the novel <b>dual-ray visibility classifier</b>, and 3) a <b>multi-view consistency optimization</b> module to drive the learned ray-surface distances to be multi-view geometry consistent. <br>
</p>
We extensively evaluate our method on three public datasets, demonstrating remarkable performance in 3D surface point reconstruction on both synthetic and challenging real-world 3D scenes, clearly surpassing existing coordinate-based and ray-based baselines. Most notably, our method achieves a <b>1000x faster</b> speed than coordinate-based methods to render an 800 x 800 depth image, showing the superiority of our method for 3D shape representation.
