Collision Issue about leaflet.pixioverlay HOT 9 CLOSED

Hi. Nice pictures!
Can you try to decrease the size of the markers? (i agree though that this is not a good solution...)

from leaflet.pixioverlay.

Can you upload the 2k dataset that crashes the fix collision function? (so that i can test it and see what can be done).

Here is zip file of the json file with the data that crashes browser when attempting to create zoom level between 5 and 16. I can get it to render the page if i only put one zoom level but not really a solution considering the density of the points.

Any feedback on the density of points when trying to calculate the collision positions

Hi. Sorry for the delay but i think that i found the root of the problem.
Can you tell if the problem happens randomly on the 2k dataset? (Sometimes the computation succeeds in a few seconds and sometimes it fails after a much longer times.)

from leaflet.pixioverlay.

I've pushed a new circles.js file that fixes the crashes with the 2k dataset. Can you check on your side?

I've added a demo with the 2k dataset here.

@manubb no worries the areas where i had issues with small amounts of points rendering due to density of the points, now seems fixed when using the new circle.js file, they render all the points with out the browser crashing. It was always crash would only render once i reduced the number of points to around 500

7k points rendered at a position was previously crashing

Thanks for your help my next option was cluster at the postgis database api and then only render one cluster point out for those areas that had issues

The collision fix function was not designed to handle efficiently many points sharing same position. If you still have performance issue with the 477k dataset, you can consider doing some preprocessing to fix collisions on the same position clusters.
