Applying Eye Shadow to Google Earth
This is an update for my London Eye, time animation, adding an animated shadow.
SketchUp has an extremely useful built-in Heliodon, simulating the precise location of the sun for any time of the year, and enabling shadow rendering. With a reasonably accurate model, it’s possible to get a good alignment match between SketchUp shadows and those in Google Earth’s imagery .
What I’ve done here is use screenshots of my wheel’s SketchUp shadows to create a time series of ground overlays in Google Earth. These move in step with the original animated 3d model of the London Eye .
The shadow images still need a bit of work (and possibly higher resolution) to make them blend in better with the rest of the ground photography. But I’ll leave that for another day… in other words, I’m not completely sure how to do it at the moment 🙂

(The viewing tips for the original animation apply to this one too.)
Here’s a basic outline of how I got the shadows from SketchUp into Google Earth:
- Copied the model into 20 separate SketchUp layers, rotating the wheel by slightly different amounts in each layer.
- Toggled on SketchUp shadow rendering, with the appropriate date and time setting – January 29, 11:30.
- Switched to SketchUp’s overhead view.
- Flipped between the layers taking screenshots of each.
- I cropped the screenshots, and added alpha transparency in PS Pro.
- Aligned a single one of these pictures in GE and created a Ground Overlay time series with the 20 pictures.
- The original GE wheel shadow is Photoshopped out with a further image overlay.
