Hi there,
I'm trying to do something that I can see others have tried to do, but i can't
find a working solution.
I have a layer with vector polygons, generated programmatically in the
JavaScript. My map is global, in 3857 proj, with dateline wrapping.. hence i
would like for the polygons to be represented multiple times when appropriate.
I have tried adding 'mirror' features, i.e. ones where the geometry is shifted
right and left by 2*2.003750834E7 meters.. however the new features are
rendered on top of the old, despite the fact their geometries are not the same.
I have tried defining the map extent to be and extra globe wide on each side.
for e.g.:
var new_feature1 = feature.clone();
var new_feature2 = feature.clone();
new_feature1.geometry.move(20037508.34*2,0);
extent_layer.addFeatures(new_feature1);
new_feature2.geometry.move(-20037508.34*2,0);
extent_layer.addFeatures(new_feature2);
console.log(new_feature1.geometry.getBounds());
console.log(new_feature2.geometry.getBounds());
the console shows the geoms are different, but they all render on top of each
other.
Is there a way to achieve this, i.e. render vectors beyond the logical extent
in order to avoid not drawing features where they indeed exist ?
(note in order to get sufficiently zoomed out with wrapDateLine=true i had to
override OpenLayers.Map.adjustZoom)
i am using OpenLayers 2.13-dev
thanks for any ideas,
-i
