MultiPolygonData

多面数据结构

new YS.MultiPolygonData(array)

multipolygon

Name	Type	Description
`array`	Array.<PolygonData>	多面数组

Examples:

//两个面组成多面
//直接使用json数据：
[{
    line: [{ x: 114,y: 35,z: 0 }, { x: 114,y: 25,z: 0 }, { x: 110,y: 25,z: 0 }, {x: 110,y: 37,z: 0 }],
    holes: []
},{
    line: [{ x: 115,y: 35,z: 0 }, { x: 115,y: 25,z: 0 }, { x: 120,y: 25,z: 0 }, {x: 120,y: 37,z: 0 }],
}]

//使用MultiPolygonData构造函数
var xyz = [{x:100,y:20,z:10},{x:100,y:20,z:10},{x:100,y:20,z:10}];
var holeLine = [{x:100,y:20,z:10},{x:100,y:20,z:10},{x:100,y:20,z:10}];
var holes = [new YS.PolygonData(holeLine)];
var data = new YS.PolygonData(xyz, holes);
var mp = new YS.MultiPolygonData([data, data2]);
