坐标转换问题：

由于控制点可以随便输入，所以本地和地理位置的转换也是可拉伸的。而navvis的转换是等比由中心展开，
所以对比两种转化方式时误差较大。

另外地理注册控制点是有参考数据集的，若参考数据集和我放置在0,0,0的数据集一致，就可直接使用，否则要转换。



---------

lonlat和空间坐标其实并非线性关系，因为lonlat其实是角度。当两个数据集在地球两端时，它们之间的夹角都相差180度了。
所以若要准确展示的话，需要将点云内所有物体，如漫游点，都先获取lonlat再去算local。或者直接将点云整体的transformMatrix考虑上在地球上相对于初始数据集的偏转。







支持ctrl+z、ctrl+Y 撤销回退的页面有：
测量、土方量、空间模型 这三个页面的点线拖拽；点云裁剪、点云下载中的裁剪 的框； 点云编辑的变换； 数据集校准；

（所有数据一旦删除则无效 ）

其他快捷键：

按alt鼠标滚轮或WS键放慢。
测量or土方量： 按Alt键可以平行拖拽点。&dragPolyBeyondPoint 后缀则可平行拖拽到无点云区域 。
按M键拖拽点可以复制出当前点 
点云按空格键+左键拖拽场景，可以不改相机位置的旋转视角
