拿到一组数据在mars3d上渲染报错排查思路

前景提要：

1.拿到一组数据，不知道怎么在mars3d上渲染

 positions: [[117.13736237725986, 46.36744915831693],[117.11316348752415, 46.37920796263987],[117.11150051793469, 46.37579082835441],[117.11934329709531, 46.37197672713472],[117.11996556958685, 46.37325882304401],[117.11828114232527, 46.37407421458465],[117.11853863439075, 46.37460529196966],[117.13658453664544, 46.36583983290777]],

2.翻了api文档，用了PolygonPrimitive方法，正常渲染了

    const graphic = new mars3d.graphic.PolygonPrimitive({positions: [[117.13736237725986, 46.36744915831693],[117.11316348752415, 46.37920796263987],[117.11150051793469, 46.37579082835441],[117.11934329709531, 46.37197672713472],[117.11996556958685, 46.37325882304401],[117.11828114232527, 46.37407421458465],[117.11853863439075, 46.37460529196966],[117.13658453664544, 46.36583983290777]],style: {color: "#00ffff",opacity: 0.4},attr: { remark: "示例1" },flyTo: true})graphicLayer.addGraphic(graphic)

3.加上材质之后报错了

    style: {height: 50,diffHeight: 300,materialType: mars3d.MaterialType.PolyGradient,materialOptions: {color: "#3388cc",alphaPower: 1.5},vertexFormat: Cesium.MaterialAppearance.MaterialSupport.TEXTURED.vertexFormat,textureCoordinates: {positions: [new Cesium.Cartesian2(0, 1),new Cesium.Cartesian2(0, 0),new Cesium.Cartesian2(0.5, 0),new Cesium.Cartesian2(1, 0),new Cesium.Cartesian2(1, 1)]},label: {text: "Mars3D平台",font_family: "楷体",color: "#ffff00",font_size: 18,setHeight: 400}},

4.注释部分材质代码，发现又能够渲染了

const graphic = new mars3d.graphic.PolygonPrimitive({positions: [[117.13736237725986, 46.36744915831693],[117.11316348752415, 46.37920796263987],[117.11150051793469, 46.37579082835441],[117.11934329709531, 46.37197672713472],[117.11996556958685, 46.37325882304401],[117.11828114232527, 46.37407421458465],[117.11853863439075, 46.37460529196966],[117.13658453664544, 46.36583983290777]],style: {height: 50,diffHeight: 300,materialType: mars3d.MaterialType.PolyGradient,materialOptions: {color: "#3388cc",alphaPower: 1.5},label: {text: "Mars3D平台",font_family: "楷体",color: "#ffff00",font_size: 18,setHeight: 400}},attr: { remark: "示例9" },flyTo: true})graphicLayer.addGraphic(graphic)

问题：

1.但是没有示例的效果，渐变材质的中心点无法在边界点的内部

解决方案：

1.暂无，只能先注释解决报错
