%description
Provides tools for weighted spatial tessellation using Euclidean and
geodesic distances within constrained polygonal domains. The package can
generate complete and connected spatial partitions that respect complex
boundaries, heterogeneous point weights, and optional resistance or
terrain effects. The methods extend weighted Voronoi tessellations to
constrained domains and graph-based cost-distance surfaces. For background
