[Blender] Sverchok and Geometry Nodes in Blender

1. M by Martin156131 on 7 Oct 2022, edited 8 Oct 2022 #

   So i do not know anything about modelling geometry with nodes, so i wanted to learn one for Blender and i found out there are already two ways:

   http://nortikin.github.io/sverchok/docs/main.html# <- Sverchok

   https://docs.blender.org/manual/en/latest/modeling/geometry_nodes/introduction.html <- Geometry Nodes

   So what is the difference?

   My endgoal is to create an ifc modell with geometry with a script or nodes not hand drawing in the gui, and for me there is the option with BlenderBIM or FreeCAD or directly trying with IfcOpenShell with PythonOCC <- I am not an expert with any of those methods -> so it would be cool to get advises, where i should first invest my time in learning :)

   Sverchok is an addon and more similar to Grasshopper, it's detailed but less performative

   Geometry nodes is built into Blender and is VERY performative but less extensive than sverchok and less precise.

   Sverchok also has some integration with Ifcnodes if I recall correctly but have not read up on it in awhile

   Good tutorials for using both Sverchok and Geometry nodes can be found here:

   There's some work on creating IFC nodes in Sverchock.

   Topologic also using sverchock i think
