Features
--------

CurviRiver takes as input a Polygon of a river segment and generates a 2D or 3D
curvilinear mesh that can be used for hydrodynamic or hydrological modeling.
The mesh is generated in three main steps:

- Determining the centerline of the input Polygon using Voroni diagram
  Dijkstra's algorithm,
- Smoothing the generated centerline with a B-spline curve,
- Computing the tangent angles of the centerline at each point along
  the centerline and generating cross-sections perpendicular to the
  centerline at given intervals,
- Generating a 2D mesh from vertices of the cross-sections,
- Generating a 3D mesh if depth data is provided, by determining the depth of
  2D mesh vertices from the depth data using Inverse Distance Weighting (IDW).
