参数

参数	类型	描述
poly	Feature <Polygon>	the polygon to tesselate

返回

FeatureCollection <Polygon> - a geometrycollection feature

示例

var poly = turf.polygon([[
  [11, 0], // 注意：polygon首尾坐标要一致 
  [22, 4], 
  [31, 0], 
  [31, 11], 
  [21, 15], 
  [11, 11], 
  [11, 0]]
]);
var triangles = turf.tesselate(poly);
