Installing

Note: A working catkin workspace is required for installation. For more information, see catkin.

Make sure you have sourced the correct setup.bash file for your ROS distribution already

Go to workspace src directory

cd /path/to/your/catkin_ws/src

Checkout the perlin_noise_filter repository

git clone https://github.com/jakedex/perlin_noise_filter

Then make sure you have all dependencies installed

cd /path/to/your/catkin_ws
rosdep install --from-paths src --ignore-src --rosdistro indigo

Now build

catkin_make

After sourcing /path/to/your/catkin_ws/devel/setup.bash you should now be able to use the perlin_noise_filter package.
