Google Maps在折线上获取LatLng

Question

I'm trying to get a marker (LatLon object) for a specific distance on top of a polyline on a Google Map.

Using the GetPointAtDistance function of epolys.js , I'm getting a point on the map that seems correct, but it is a little "off" the Polyline that the map generated.

Here is an example I put together to demonstrate my issue: http://jsfiddle.net/S7VPz/2/

Preferably, I would also like to use a geodesic polyline instead of a straight one.

对于此特定的折线（两点之间的测地线）， google.maps.geometry.spherical.interpolate()似乎很完美： http : //jsfiddle.net/doktormolle/2nAgr/
