The 3D companies in the Metaverse consortium like Autodesk are ALL polygons and Nurbs software vendors.
So in terms of the actual 3D design/modeling techniques used the Metaverse probably won’t change much initially.
What will change the most will likely be that they port their software to ru in a VR-like immersive 3D space.
So instead of seeing stuff in a OpenGL viewport, you’ll be standing around it or walking around it in VR.
