代码：
export function showDraw(isFlyTo) {
removeLayer()
graphicLayer = new mars3d.layer.GeoJsonLayer({
data: {
type: "FeatureCollection",
features: [
{
type: "Feature",
geometry: {
type: "Point",
coordinates: [121.453893, 29.888391],
},
properties: {
gid: "1",
code: "1718850737365",
type: 'circleP',
style: {
radius: 1693.63
}
},
id: "fid--45368680_1902ac1ce0f_-7fde",
},
],
},
symbol: {
styleOptions: {
color: "#FF0000",
},
},
flyTo: true
});
map.addLayer(graphicLayer);
}
效果：
报错：
Cesium.js:15236 An error occurred while rendering. Rendering has stopped.
DeveloperError: normalized result is not a number
Error
处理办法：
设置下 merge为true即可，
正确代码：
export function showDraw(isFlyTo) {
removeLayer()
graphicLayer = new mars3d.layer.GeoJsonLayer({
data: {
type: "FeatureCollection",
features: [
{
type: "Feature",
geometry: {
type: "Point",
coordinates: [121.453893, 29.888391],
},
properties: {
gid: "1",
code: "1718850737365",
type: 'circleP',
style: {
radius: 1693.63
}
},
id: "fid--45368680_1902ac1ce0f_-7fde",
},
],
},
symbol: {
merge: true,
styleOptions: {
color: "#FF0000",
},
},
flyTo: true
});
map.addLayer(graphicLayer);
}
正常效果：
原因：
1.内置的style与symbol配置冲突，需要合并并覆盖json中已有的style
