This is a showcase of a projection mapping helper tool called Chaser ( http://chaser.hybridvisuals.nl/try/ )
The app loads the input mapping you’ve made in Arena’s Advanced Output. You can then create bumps and chasers by toggling your slices on and off. The plugin is used as an effect on your content. It can play the chasers you've just created in the app and will show the content using the patterns you created there.
