Detailed Description
Implements the SignedDFInterface for common 2-D geometric objects.
This file provides signed distance functions for common 2-D geometric objects:
- Circle
- Rectangle
- Note
- The signed distance functions should be the shortest distance between a point and any point on the surface. This is hard to calculate in many cases, so we use contours here. The surface layer may not be equally thick around all points on the surface. Some shapes have the exact shortest distances, which will be noted on a class-by-class basis. Serious usage of the contour-based signed distance functions is not recommended.
