Create a workspace (if you do not have one yet), clone this repository and compile it:

mkdir ws && cd ws && mkdir src && cd src
git clone https://github.com/jtorde/planning_worlds_gazebo.git
#cd planning_worlds_gazebo && git checkout -b feature/melodic origin/feature/melodic && cd .. #run this ONLY if you are using ROS Melodic or ROS Noetic
cd ..
catkin build
source devel/setup.bash 

roslaunch planning_worlds_gazebo start_world.launch

(the world name is specified can be modified in the launch file or in the command line)

In one terminal:

roslaunch gazebo_ros empty_world.launch

And in other one:

rosrun planning_worlds_gazebo create_random_forest

The cylinders will start to populate the world with the density specified in create_random_forest.cpp.
