Geometry nodes and multiple representations

S by stephen_l on 21 Apr 2021, edited 22 Apr 2021 # +9 votes

Blender's Geometry nodes now provide a new node allowing to switch between different geometry representations (lod like)

So may be a possible solution to store multiple representations of a single object right in blender and switch on demand using python to automate the process.

Any ideas how Blender stores this internally in its data model? Right now, I simply store different bpy.data.Mesh.

You may rely to data.mesh through object info node or node based full parametric entity using nodes primitives and booleans.

This is a revolution in blender's world, providing a true support for parametric objects out of the box, without drivers, but may be a bit compicated to properly setup a node tree for complex objects.
