Webb22 maj 2024 · The MATLAB contours function creates coordinate data that (when the shape is closed) has a coordinate point that starts and ends on the same point. The decsg function, however, only asks for the coordinate point at the beginning point of the edge for a polygon, this was causing problems when run iteratively - but was fine when run for …WebbOptimizable Geometry - Python API. This section covers the details of shape and topology based inverse design using lumopt. As prerequisite please familiarize yourself with photonic inverse design and understand the basics of the lumopt workflow. The following examples can help provide context to the information presented here.
