Hi All, I am just starting off with Gazebo to perform some multirobot simulations. In order to keep our project relevant to the topic, I wanted to perform these simulations in a visually relevant environment rather than a box world with obstacles. We have some ground truth models created using Faro Scans of the test site. I wanted to use these models as my Gazebo world and perform the simulations in there. Does anyone know if it is possible ? Thanks Ammar

I assume the Faro scans are point cloud data. You would have to create a polygon representation out of that (for example using Meshlab) and save that as a .dae or .stl file. You can then use that inside a gazebo model and load it.

I did the same with a landscape modeled in Blender (COLLADA named "120m_landscape_smooth_tri.dae").

Here's the world file for electric's gazebo: http://code.google.com/p/tu-darmstadt-ros-pkg/source/browse/branches/electric/hector_gazebo/hector_gazebo_worlds/worlds/rolling_landscape_120m.world

and here for fuerte: http://code.google.com/p/tu-darmstadt-ros-pkg/source/browse/branches/fuerte/hector_gazebo/hector_gazebo_worlds/worlds/rolling_landscape_120m.world
