FlyTo with Roll

Jun 24, 2010 at 9:20 AM
Hi I see that the FlyTo does not contain a parameter for Roll, so I assume I should just change the Roll seperately. I code :- VEMap.FlyTo(New VELatLong(LATITUDE, LONGITUDE), PITCH, YAW, ALTITUDE) then VEMap.Roll = ROLL but, the roll angle is just correct for a flicker and the horizon goes horizontal again. I've tried doing the Roll first, but the same thing happens. How do I FlyTo and set my current Roll at the same time?? Thanks in advance. Jason.

Jason, When you do FlyTo it overwrites the camera parameters until the animation is complete. VEMap.FlyTo just calls the GlobeControl.FlyTo: this.globeControl.Host.Navigation.FlyTo(lla, pitch, yaw, false, cam); That method does not take a roll parameter, so you have two options: 1) Pass an event handler for a callback to FlyTo and it will be called when the animation is complete. At that point either set the roll or animate the roll using a storyboard or timer. 2) If you really need the roll to animate at the same time as the FlyTo, you'll have to get your hands dirty and write a custom camera controller.
