The Visualization Toolkit (VTK) is an open source library for scientific data visualization. BVTKNodes is a Blender addon to create and execute VTK pipelines in Blender Node Editor. The add-on is based on automatic generation of Blender Node classes from VTK Python classes. A manually programmed node class can supercede automatically generated code where needed.
BVTKNodes provides Blender users access to data readers for many scientific data formats, along with capability to convert VTK data into a Blender mesh. For VTK users, the add-on provides access to high quality rendering and many kind of mesh editing tools. The add-on was presented at Blender Conference 2018

BVTKNodes add-on requires VTK version 8.2.0 and VTK python wrappers compatible with the python version used in Blender. Another VTK version (>7) may be alternatively used, if generated class definitions (gen_VTK*.py files) are also updated (by running populate_db.py and generate.py. Warning: Modifications may be required). See VTK building instructions for Linux.
