I have a gmap with direction line displayed on it (2 or more points). Is there any way to get all points from map depending viewport (zoom level), only those that user can see ?

I won’t give you the tea spoon version, but here is how you do it. First of all, make sure you have all your markers available in an array.
map.getBounds(). This will return aLatLngBoundsobject, which contains the coordinates of the bottom left point of your viewport as well as the top right part.marker.getPosition()and check if they are above and to the right of the map bounds south west point, as well as below and to the left of the map bounds north east point.That array now contains all the points in your viewport. Repeat as necessary.
