supermapol的版本 面不能贴原生3Dtiles对象

0 投票

同样的代码,若引用http://www.supermapol.com/earth/Build/Cesium/Cesium.js,面不能贴原生3dtiles对象,只能贴地形。

若引用10i sp2版本的Cesium.js则既能贴3dtiles也能贴地形。

另外,在量算贴地面积时,supermapol的版本不能贴3dtiles对象,但10i sp2版本可以,但sp2版本也存在问题,就是在量算时会影响已有polygon对象,清除量算结果时会报异常。总之,2个版本各有各的问题。

测试3dtiles下载地址:

链接: https://pan.baidu.com/s/1gFJxdlldqvr9nO4ZngYSiQ 提取码: 5yie

解压后放到\SuperMap_iClient3D_10i(2020)_sp2_for_WebGL\examples\webgl\data\3dtiles目录下。本地部署运行。

另外吐个槽,标题限制40个字符实在太少了,含英文单词的标题就写不了几个汉字了。

经验证,3D模式下,面可以贴3dtiles了。但切换到2D或哥伦布视图时仍然只能贴地形,对比Cesium官网例子不管哪种视图都能自由设置贴地形或贴对象,https://sandcastle.cesium.com/?src=Classification%20Types.html,请帮忙修复。
