根据样例http://support.supermap.com.cn:8090/webgl/examples/editor.html#addSymbols,
s3mInstanceColc = new Cesium.S3MInstanceCollection(scene._context);这一句出现
- t
- message:"options.url is required."
- name:"DeveloperError"
- stack:"Error↵ at new t (eval at <anonymous> (http://localhost:8090/webgl/Build/Cesium/Cesium.js:25:1), <anonymous>:1:3281)↵ at new k (eval at <anonymous> (http://localhost:8090/webgl/Build/Cesium/Cesium.js:25:1), <anonymous>:1:2058809)↵ at button13_click (http://localhost:8090/webgl/examples/S3MTiles.html:882:23)↵ at HTMLInputElement.onclick (http://localhost:8090/webgl/examples/S3MTiles.html:63:75)"
