I'm trying to use the heightMap but doesn't work. I get the message:
creating /tmp/gazebo-paolo-0/graphics3d.default 112 1629744
terminate called after throwing an instance of 'Ogre::InvalidParametersException'
what(): OGRE EXCEPTION(2:InvalidParametersException): World geometry is not supported by the generic SceneManager. in SceneManager::setWorldGeometry at OgreSceneManager.cpp (line 1423)
My OGRE is 1.6.2 and well installed, and gazebo svn.
I use the following tags in the world file
but it seems to me that the map doesn't provide a 3d representation of the png image but only its extrusion with a certain threshold on the darkness of a point to consider the point wall or nothing.
Is this correct?
