Spatial Filter for Avoid Polygons

[JoStroh]

Couldn't the _get_avoid_polygons function be provided with a spatial filter? So that only features that are “near” the input points are selected. You would simply have to create a bounding box around the list of input points and add a QgsFeatureRequest to the function.

Hi, thanks for your idea here. The problem with that would be that it's not possible to know whether the route will exclusively lie within the bounding box of the input points.

If you describe your problem a little further, we can maybe still help you out. Feel free to let us know!
