Surface4D

4D surface shader for Unity

How to play the demo scene

Create an empty 3D project in Unity.
From Package Manager, install the Mathematics package.
Drag and drop the downloaded Surface4D folder to Assets in the project browser.
In Project Settings -> Player -> XR Settings, tick Virtual Reality Supported.
Open Scenes/Hypercube or Scenes/Hypercube_Klein by double clicking the icon in the project browser.
(optional) Add the definition of a triangulated mesh in the 4D space that is written in C# as Scripts/GenerateHypercube.cs and Scripts/GenerateKleinbottle.cs. To render the newly added mesh, first duplicate the scene's Hypercube object, and assign the script to it as a component. Then, turn off Generate Hypercube (Script).
Put on your HMD and start the game engine by pressing play button.
