 [Playerstage-users] newbie question for player stage for modeling slope map From: logicalguy - 2011-05-30 11:51:59 ```Hi, I'm a newbie to player/stage/gazebo, so please be patient with me and help me out, thanks :) What I'm trying to achieve is analyse a slope map and create a world in stage which I can use for path planning algorithms, like A*. or the built in VFH. Is there any way to represent height/elevation in a stage world? If I have a canvas with regions indicating obstacles, is there any way to indicate the height/slope of the obstacles in any way? Colour coding is impossible, I believe. Would gazebo be able to do this? Sorry if this seems like a naive question - we all have to begin somewhere! Thanks, and hoping for quick replies. -- View this message in context: http://old.nabble.com/newbie-question-for-player-stage-for-modeling-slope-map-tp31732721p31732721.html Sent from the playerstage-users mailing list archive at Nabble.com. ```

You can use Gazebo instead, which is a 3D simulator.

 Re: [Playerstage-users] newbie question for player stage for modeling slope map From: logicalguy - 2011-05-30 13:29:27 ```Thank you for quick response. I also got a response to this question in my email and this is what it is: You CAN represent height/elevation in a stage world, but unfortunately you can't represent slope. Stage is intended as a 2.5D simulation. So your robots are all driving on a 2D plane, and the obstacles in the environment can have varying height. If you wanted a robot to be able to change elevations based on what they're driving on you'd need to modify it some how. I think Gazebo is what you're looking for. Tyler ----------------------------------- Is there any one who has represented height in a stage world who is willing to show me how its done? Can I query this information programmatically? Thanks again for your answers. -- View this message in context: http://old.nabble.com/newbie-question-for-player-stage-for-modeling-slope-map-tp31732721p31733310.html Sent from the playerstage-users mailing list archive at Nabble.com. ```
