%global _empty_manifest_terminate_build 0 Name: python-mapbox-earcut Version: 1.0.1 Release: 1 Summary: Python bindings for the mapbox earcut C++ polygon triangulation library. License: ISC URL: https://github.com/skogler/mapbox_earcut_python Source0: https://mirrors.nju.edu.cn/pypi/web/packages/97/f9/38f72877be0a5bf35c04a75c8ceb261589f2807eeaffaa22055079f53839/mapbox_earcut-1.0.1.tar.gz Requires: python3-numpy Requires: python3-pytest %description # mapbox_earcut Python bindings for the C++ implementation of the Mapbox Earcut library, which provides very fast and quite robust triangulation of 2D polygons. Original code: [earcut.hpp](https://github.com/mapbox/earcut.hpp) Original description: > The library implements a modified ear slicing algorithm, optimized by > [z-order curve](http://en.wikipedia.org/wiki/Z-order_curve) hashing and > extended to handle holes, twisted polygons, degeneracies and self-intersections > in a way that doesn't _guarantee_ correctness of triangulation, but attempts to > always produce acceptable results for practical data like geographical shapes. Provided functions (depending on dtype of vertex data): ```python triangulate_float32 triangulate_float64 triangulate_int32 triangulate_int64 ``` Example: ```python import mapbox_earcut as earcut import numpy as np # A Nx2 array of vertices. Must be 2D. verts = np.array([[0, 0], [1, 0], [1, 1]]).reshape(-1, 2) # An array of end-indices for each ring. # The first ring is the outer contour of the polygon. # Subsequent ones are holes. # This implies that the last index must always be equal to the size of verts! rings = np.array([3]) result = earcut.triangulate_float32(verts, rings) # Result is an np.ndarray with dtype np.uint32 and shape (3,) # containing indices into the verts array. print(verts[result]) # [[1 0] # [1 1] # [0 0]] ``` %package -n python3-mapbox-earcut Summary: Python bindings for the mapbox earcut C++ polygon triangulation library.
