MarkerClusterer & Google Maps API v3

[Solo]

Do anybody knows about plans to create MarkerClusterer version for
Google Maps API v3?

[Björn Brala]

Im currently working on it, but it still has some bugs and im a bit short on time. It will be ported tho.

Great. I just ported my application to version 3. Was planning to
implement MarkerClusterer later but at the moment I have to postpone
it due lack of v3 support.

Cheers,
Espen

Any updates on how porting is going?

Is there anything we can do to help complete it?

This is just my assumption. I haven't discussed with Björn but I think
he would like people starring the feature request concerning LatLng-to-
pixel method.

Hi, yes I'd also like to understand when marker clusterer will be
ready. Really need it! Thanks.

Björn:
Why don't you check the code into SVN, maybe other folks can help out.

The file:

www.polyarc.us/adjust.js

contains conversion functions.

var offset=268435456;
var radius=offset/Math.PI;

function LToX(x)
{
return Math.round(offset+radius*x*Math.PI/180);
}

function LToY(y)
{
return Math.round(offset-radius*Math.log((1+Math.sin(y*Math.PI/180))/
(1-Math.sin(y*Math.PI/180)))/2);
}

function XToL(x)
{
return ((Math.round(x)-offset)/radius)*180/Math.PI;
}

function YToL(y)
{
return (Math.PI/2-2*Math.atan(Math.exp((Math.round(y)-offset)/
radius)))*180/Math.PI;
}

For a specific zoom level, you can shift the results of LToX & LToY by
(21-z).

xPixel = LToX(lng)>>(21-z);
yPixel = LToY(lat)>>(21-z);

The absolute pixel postions can be converted to relative pixel
positions with fixed X & Y offsets without repeated use of
"fromLatLngToDivPixel" which requires a new LatLng object for each
call. Just do it once for a known position like the center of the
map. The difference between absolute position & relative position
will not change unless the "offset" changes which will trigger another
event.

I just came back from vacation.

It has been checked in before my vacation, also, please star the issue earlier in this thread!

Has there been any progress with the MarkerClusterer for V3?

If not, then I'd be happy to take a look at getting it done and into
SVN. Is there any source code (incomplete or buggy is fine so long as
there are some comments/todos) that anyone can offer in this
direction?

Cheers,

Gary

[websiteman]

Is there still some development and can this be shared? We would love
to help develop it further.

[Huan Erdao]

Ive already shared to websiteman via twitter,

I've made some of it working for my app.
it does not provide rich api as markerclusterer for v2, but if you
want to hack on it,
this is what I did.

http://code.google.com/p/android-playground-erdao/source/browse/#svn/trunk/markerclusterer_for_v3_api

hope this ifo help.

[Earthware]

Has any one ported the ability to keep an marker as a normal marker
when there is only one marker in a cluster?

I just discovered the Fluster project, which does the same job as
MarkerClusterer but for v3: http://sourceforge.net/projects/fluster/

Did anyone try ?
