<div dir="ltr">I took this particular road only to have a gui to draw in. This was an interactive musical project, where people equipped with a smartphone would trigger different sounds or events by visiting a city. The patch i've sent could be easily reduced to a single object taking the polygon's points coordinates and a position, only telling if the point is inside the polygon or not.<br></div><div class="gmail_extra"><br><div class="gmail_quote">2017-04-20 12:53 GMT+02:00 patrice colet <span dir="ltr"><<a href="mailto:colet.patrice@free.fr" target="_blank">colet.patrice@free.fr</a>></span>:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> If it's about mouse binding in [gemwin], the math is really heavy, particulary if the camera is moving.<br>
<br>
It can be solved differently by rendering the polygons in an hidden frame or another gemwin, and set a different color for each new polygon, the binding will be about detecting color under mouse cursor with the help of [pix_snap] and [pix_data] and it will work even if the camera is moving.<span class=""><br>

I think so for point in polygon, see attached. It's an old attempt of mine, with a mechanism to draw polygons in Gem and then tell in which polygon your mouse pointer is.<br>

Did someone here solve this in Pd before?<br>
