yeah that's what the example does, but the fixed displacement is in mercator units (map pixels) and the polylines are stored in latlngs, so there's large overhead reprojecting the data. To remove the reprojection overhead, I'll do an example with the data in mercator using raw SVG/VML. This will also give a performance comparison with the V3 google.maps.Polyline, which is a heavyweight implementation. I am sure that javascript will be quick enough for the parallel calculations. -- You received this message because you are subscribed to the Google Groups "Google Maps JavaScript API v3" group.
