Here is what the finished product might look like with saved snapshot views. Now when you double-click on the folder in the Places panel, Google Earth will fly to that saved view, or perspective. To do this, right-click on the folder in the Places panel, and choose Snapshot View. You can also assign a Snapshot View to a folder. Now, when you double-click on that placemark in the 3D viewer or in the Places panel, Google Earth will fly to that saved view, or perspective. Go to the View tab, and click the Snapshot Current View button. To open the Properties, right-click on the placemark in the 3D viewer or in the Places panel, and choose Properties (on a PC) or Get Info (on a Mac). You can also set the Snapshot View in the Properties window click on the Snapshot current view button, as shown below. Using Snapshot Views can be very effective for telling stories and guiding users through your Google Earth layer in a controlled manner, helping them get the unique perspectives you want them to see. This will save your unique camera angle, or perspective, for this placemark. Right-click on the “Flirt” placemark in the Places panel, and select Snapshot View. Below the navigation controls on the right, you’ll see Pegman. For example, zoom into the placemark labeled “Flirt”, and tilt and rotate the Earth to a unique perspective. Zoom in on the location you want to see using: Your mouse or touchpad. If youre already in 3D view, you’ll find 2D instead. Use the mouse or the navigation tools to orient the Earth to a unique perspective for a placemark. Make use of Google Earths detailed globe by tilting the map to save a perfect 3D view or diving into Street View for a 360 experience. Switch between top-down view and orbiting 3D view: At the bottom right, click 3D. And scroll through the dates to see all the satellite images from different days of the year. Look for the date the picture was taken from the bottom left hand corner of the screen. how there is no unique camera angle, or perspective, set for the placemarks - when you double-click on a placemark, the Earth doesn't tilt or rotate to a unique perspective. To move from an aerial view to a view as if looking from the Earth, use the horizontal bar in the right hand corner. const camRadiusTilStart = 60 // Camera radius (i.e zoom) at which the tilt effect beginsĬonst camRadiusTiltEnd = 10 // Camera radius at which the tolt reaches its maximumĬonst cameraBetaStart = camera.beta // Controls the tilt effect when camera is zoomed outĬonst cameraBetaEnd = camera.beta * 2.2 // Controls the tilt effect when camera is zoomed in It modifies the camera’s beta property based on its radius (i.e the current zoom level). Make use of Google Earths detailed globe by tilting the map to save a perfect 3D view or diving into Street View for a 360 experience. Hi a solution that uses the onBeforeRenderObservable to run an update loop. These are just a couple of things that come to mind so hopefully, this gives you a starting place. If you want to that behavior to be with left-click instead, you could just change your attachControl call to something like // First param doesn't matter, second is for noPreventDefault, third is for using ctrl for panning, and the fourth is to change your panning button to left clickĬamera.attachControl(canvas, true, false, 0) įor adding a limit, you may need to either use a custom solution that checks for the target’s position before moving or possibly add an observer/callback to one of the camera’s observables like onViewMatrixChangedObservable to zero out the inertialPanningX and/or inertialPanningY values if the target gets to a specific boundary (these inertial panning values are used to smoothly move the camera with inertia if input is received zero-ing them is effectively the same as cancelling any remaining movement). By default, panning is handled with a Right-click drag. You can also use your upper and lower beta limits to prevent the camera from moving to an undesired angle.įor panning, the ArcRotateCamera does have built-in panning and I believe also has a flag for map panning, which should eliminate any vertical movement. You could even use a Scalar.Lerp to a smoother transition. The tilting as you zoom in could be as simple as modifying your camera’s beta with respect to your camera’s radius. Since you’re using an ArcRotateCamera, it shouldn’t be too difficult to accomplish what you’re trying to do.
