Powerwall Unity package

Abstract

Small unity package with the aim to create a perspective projection on a Powerwall. Hardware is a ViveTracker and a Projector. The ViveTracker position is provided by SteamVR. Unity can access the position either through SteamVR-Plugin (Asset store) or in the future with the OpenXR package. Currently the OpenXR does only support controllers (left and right hand) but not the ViveTracker

Requirements

• SteamVR installed as app (tested with 1.20)
• Download SteamVR-Plugin and place it in the Plugin folder of the package
