Quick Reference

What Are Sverchok Extensions

Sverchok extensions are Blender add-ons that register additional nodes into Sverchok's node editor. They follow a standard pattern: a bl_info dictionary, a nodes_index() function that declares node categories and classes, and register()/unregister() functions that hook into Sverchok's menu and node discovery system.

• Sverchok-Open3d: Point cloud and mesh processing via Open3D by Victor Doval
• Mega-Polis: Urban design and GIS data integration
• Ladybug Tools: Environmental analysis (weather, radiation, comfort)
• Sverchok-Bmesh: BMesh operations within Sverchok
• TopologicSverchok: Non-manifold topology (covered in skill sverchok-impl-topologic)

Critical Warnings

NEVER assume Sverchok-Extra nodes are available without checking — they require optional dependencies (SciPy, python-sdf). Use dependency guards in code that references these nodes.
