Barnabu is at it again adding more realism to an animated ferris wheel. Previously Barnabu was shown with a 4D animation of the London Eye where he used a modified ground image to remove the projected image of the ferris wheel from the ground (from the satellite photo). Now he has also added the shadow from the ferris wheel as it animates by using a feature in Google SketchUp (a 3D modeling tool) for projecting shadows. You can view the London Eye with shadows animation (860 KBytes) directly in Google Earth.
Follow these instructions (from Barnabu):
- After the file loads look for the time slider control at the top of the screen
- Access the time control options via the white clock face to the left of this
- Set the repeat mode to ‘wrap’
- Ensure that ‘clamp beginning of time window’ is off
- Click OK
- Hit the play button (the triangular right arrow).
- If need be, the speed can be varied via the time control options
- GE takes a little while to load in all the separate parts of the animation, resulting in flickering for a few cycles
An animating 3D model like this is best viewed with the view tilted so you can see both the moving ferris wheel and the shadow. It’s even better if you move around while it is animating with something like the SpaceNavigator. See the link below for a video showing what this looks like.
