info window

[geraldstanje]

Hi @brendankenny,

in your presentation you showed an info window: https://youtu.be/aZJnI6hxr-c?t=2009

could you post your canvas event listener code and how you store all lat/long points for lookup?

Thanks

My hunch is that the lat/longs along with the other information from ships are stored on a file, loaded into an array that gets loaded on the Canvas Layer (webgl). When clicked he just gets the index number from webgl (if I were using Three.js I'd get the index number using raycasting), and then open an infowindow on Google Maps looking up the info on the array loaded from the file.

@caioiglesias a point is on the map is represented by: the coordinate (x,y) of the point, size of the point, an off screen color, and an on screen color. what is the off/onscreen color used for? how are they stored and rendered?
