Currently I use Cesium 1.19, I need to draw a polygon as a rectangle.
Until then, I can draw this polygon but using 4 points to place. (I click on the map and I recovered coordinated to draw this polygon as the figure below (Figure 1))
Now I ask you, if possible, of tutorial or code snippet showing a mouse movement polygon tracing (Figure2.swf.html)
