Earcut triangulation

WebEar cutting (or ear clipping) applies constrained triangulation by successively 'cutting' triangles from a polygon defined by path/s. Holes are supported, the earcut library works with single-island-with-holes polygons, analogous to the POLYGON type in simple features.

Use the vertices returned from Clipper and feed it into a triangulation algorithm. Use the triangles returned from the triangulation algorithm, and the vertices from Clipper, to construct a mesh, along with its normals and UVs.

WebAfter getting a triangulation, you can verify its correctness with Phaser.Geom.Polygon.Earcut.deviation: var deviation = earcut.deviation(vertices, holes, dimensions, triangles); Returns the relative difference between the total area of triangles and the area of the input polygon. 0 means the triangulation is fully correct.

Webear – a set of three consecutive vertices of the polygon that form a triangle containing no other vertex than those three. The algorithm goes as follows: For a simple polygon, find an ear, remove it from the shape and proceed until there is only one final triangle left.
