About CesiumFlyToController Scripts

[jh007]

I have a question about the CesiumFlyToController script. Currently, the implemented flight involves the camera flying to a certain position and setting the rotation of the X and Y axes. However, I want to focus on a specific latitude and longitude. That is, when flying over, the object at the focused latitude and longitude is exactly in the center of the screen, and the distance from the camera is set as a parameter: distance . How can this be implemented?

Hi @jh007,

I don’t think we’ve ever attempted to implement that! But, it sounds like you might need to compute the offset between your desired longitude / latitude, and the actual long / lat that the camera will fly to.

You could start with the desired long / lat, convert it to a Unity position, then subtract your desired offset from that Unity distance. Then, you can re-convert that final Unity position to long/lat. For the conversions, you could use:

• LongitudeLatitudeHeightToEarthCenteredEarthFixed and EarthCenteredEarthFixedToLongitudeLatitudeHeight on CesiumWgs84Ellipsoid
• TransformEarthCenteredEarthFixedPositionToUnity and TransformUnityPositionToEarthCenteredEarthFixed on CesiumGeoreference.

I hope this gives you a good starting point!

I also see that Kevin gave a more detailed solution here

In the future, it’s probably best to start a new thread when you’re asking a new question. There’s nothing built-in to do what you describe, but you can implement it yourself. But first you need to be clear about exactly where you want the camera to look at your target from. If you really don’t care about that, the easiest thing by far is to have the camera be directly above the target and looking straight down. To do that, call FlyToLocationLongitudeLatitudeHeight with the exact longitude and …
