costmap_subscript/indexhtml_79.txt | The ` nav2_waypoint_follower ` contains a waypoint following program with a
plugin interface for specific task executors. This is useful if you need to go
to a given location and complete a specific task like take a picture, pick up
a box, or wait for user input. It is a nice demo application for how to use
Nav2 in a ... | |

costmap_subscript/3017_302.txt | I think that's out of scope of what we define as what a "costmap filter" is in
the documentation. Its a rastered map of cost. The vectorized information is
not a rastered map and there isn't the same kind of ` costmap filter info `
conversion to be done to convert costs into actions. But we could adjust that

costmap_subscript/3017_177.txt | Separate of this topic, but I also wonder if it would be nice to have a ` fill
` option, I think in some cases it wouldn't really matter to fill in the
polygon with cost, rather just make a solid costed outline so that the
planners / controllers cannot pass.
