I am trying to use the heightmap/terrains inside of Gazebo SVN, however objects seem to hover a significant distance above the actual terrain. I have traced the problem to the Ogre RaySceneQuery. It seems (at least for me) that this returns rather inexact information when the ray goes in the Z direction. In previous Gazebo revisions (R215 and before), the RaySceneQuery was oriented in Ogre's preferred Y direction, which returns usable values. Unfortunately, I have yet to find a solution other than reverting back to Ogre's coordinate system. If you have any other thoughts on the matter, I will happily explore them. Stephen Williams |

I've been able to reproduce this with the terrain.world file included with Gazebo. A screenshot of this can be seen at: http://mikeasoft.com/~mike/terrain-bug.png Cheers, Mike.

I believe the terrain problem has now been fixed. -nate On Thu, Feb 7, 2008 at 4:36 PM, Michael Sheldon <mi...@mi...> wrote: > I've been able to reproduce this with the terrain.world file included > with Gazebo.
