Overview

<p align="center"> <img src="figs/overviews.png" width="780" /> </p>

We propose GridPull to speed up the learning of implicit function from large scale point clouds. GridPull does not require learned priors or point normal, and directly infers a distance field from a point cloud without using any neural components. We infer the distance field on grids near the surface, which reduces the number of grids we need to infer. Our loss function encourages continuous distances and consistent gradients in the field, which makes up the lack of continuousness brought by neural networks.
