Considering how .svg editing has Bezier curves, there should be a 3D vector system that works with Bezier curves. Since 3D models are still always polygonal, maybe we can make our own 3D vector system as a Scratch project.

Features I want it to have:

• Redundantly, Bezier curves for models.
  

• The option to switch to points as in this website's vector editor.
  

• Rendering with raycasting.
  

• Vector based textures a mappings.
  

• More to come in the future…
