Behind The Matrix Shader Source Code

Shader code used in boths matrix video

Shader Library

XPARCommon.ginc

Useful functions to be to be reused in shader

• Depth to Distance
• Depth to World Position
• UNITY_EDITOR emulation : when the #define is used, a rendertexture can be used to simulate a depth camera. In that case, the texture contains the depth (and not the distance as it is for a physical camera) but the library does the conversion between the two modes

PortalCommon.ginc

Specific functions to display a portal in the scene

• PORTALDOOR : outside view
• PORTALWALL : inside view
• _Portal : rendered texture of the portal frame

Shaders

Depth Buffer Shader	Worlspace Shader	Triplanar Shader
Display the depth buffer	Display a grid on top of the mesh in the worldspace coordinate	Display a triplanar texture on top of the mesh, with portal support

Sample Unity Project

Sample Unity project using the Universal Render Pipeline and ARFoundation. (Using a light version of the Triplanar shader)
