Hello!
I’ve noticed strange navigation behaviour if you open map with terrain: camera rotates around itself (not around a point on the ground), pans and zooms slowly.
It looks like that picked point is very close to display, not ground. You can see this in https://d3h9zulrmcj1j6.cloudfront.net/Marseille_Cesium/App/index.html
or in sandcastle on examples with terrain. If you wait until terrain fully loaded this bug will disappear
Especially it’s noticable if you use Firefox (for example in v.53.0.3 )
Hi Andrey!
Thanks for sharing this problem. I’m having some difficulty reproducing the issue. Would you mind sharing a screen capture? Also, what OS, video card and release version are you using?
Thanks,
Thank you Rachel,
It is very noticable especially if you see area with mountains.
I can reproduce it in Cesium 1.33
OS: Windows 10, Windows 7
Video card Radeon RX 460
CPU Core i5-7400
I’ve recorded behaviour for pressed left and middle buttons for https://d3h9zulrmcj1j6.cloudfront.net/Marseille_Cesium/App/index.html:


Hi Andrey,
Thank you for providing specifics! However, we’re still having some trouble reproducing the issue on our systems. Can you provide a working Sandcastle example? To do that, following the “Sharing” instructions here: http://cesiumjs.org/tutorials/Sandcastle-Tutorial/
Thanks,
