Cubism Effect in Shader in Unity 3D

In the repo you will find code for achieving a cubist like effect on meshes. The effect is done in vertex shader by adjusting camera view matrix per voronoi segment (created based on world space coordinates), so that each segment is viewed from different perspective.

The mesh is not in the repo, you can grab it on sketchfab.The mesh used for show case the shade is from The Hallwyl Museum, scanned by ErikLernestal.
