2d-sdf-net

This is a neural network approximating the two-dimensional signed distance functions of polygons. The network structure references DeepSDF: https://github.com/facebookresearch/DeepSDF.

Intro

• The signed distance function determines the minimum distance of a point to the boundary of a curve.
• The function is negative inside and positive outside.
• The zero-contour is the boundary of the curve.
