I would like to tilt the Earth,so I use GlobeControl.Host.BindingsManager.NavControl.NavTilt method to tilt, but It is very difficult to control the Earth's tilt。

Have you seen the VEMap.Roll .Pitch and .Yaw properties?

Set VEMap.Roll. Pitch and. Yaw properties and calling NavTilt method, not the same as the Earth display

set map.Pitch = angle; (-90<angle<=180)

then zoomin or zoomout , the direction would change 180.

why???

i've been able to set the map pitch, and I've confined the pitch between -90 and 0.  but as the pitch approaches 0 the globe moves off the bottom of the screen.  how can I prevent this?

Sorry, I'm not sure about these behaviors.  They're just how VE3D processes things. 

As for pitch = 0, that's the same as if you are standing on the Earth looking towards the horizon.  Pitch = -90 is looking towards the center of the Earth.  The same applies when your altitude puts you way up in space.  Imagine you are standing on Earth looking at the horizon, but then you move 1000 miles straight up without moving your head.  The Earth would indeed be below your field of view.
