This is a project using Unity and Vuforia engine, simulating the famous scene “Execute order 66” in Star War III when the storm troopers receiving order through hologram from Palpatine. To simulate the scene, I added two shaders in the scene. The first one is the hologram shader. Sampling a stripe texture and and making it scroll over time could simply create the effect. To make it look even cool, I added some frenel component at the surface. The second one is the rain ripple shader, I created it by using an animation sheet already created. Then I also do time sampling on it to create rain ripples. To make it look more realistic and avoid obvious repetitive pattern, I mix two of them with different tiling parameter and offset. At the end of the demo, I added two physical buttons on phone to let users rate the experience.
