50 Bouncing Google Earth Globes

September 10th, 2007 Leave a comment Go to comments

This is a belated follow-up to my bouncing globe in Google Earth animation.  With forty-nine additional globes , and bounce collisions dampened to introduce some variety.

Here’s a video showing it running in real time in Google Earth…

…and the KML:

Bouncing Globes (1MB,  Google Earth v4.2 Required)

CAUTION.  The file is heavy on resources.  Depending on your system it may take up to a few minutes to load.  

I suggest playing it back on a slow speed setting, in bounce mode. To access the time options click the white clock face to the left of the time slider gadget – make sure ‘Clamp to beginning of Window’  isn’t selected.

Once the file has loaded into memory, it’s remarkable just how well Google Earth 4.2 copes with so much data – the KML consists of around 20,000 separate 3D Model positions plus the same number of Image Overlays (for the shadows).  However, GE will hang if the time control is widened.

For those interested in such things, the file was generated by Python script using the SUVAT equations for the physics.
