For *2.79*, see [special installation instructions](https://github.com/nortikin/sverchok/wiki/Sverchok-for-Blender-2.79-installation). **License**: [GPL3](http://www.gnu.org/licenses/quick-guide-gplv3.html) **Prerequisites**: Some optional nodes require additional libraries. See this [wiki page](https://github.com/nortikin/sverchok/wiki/Dependencies) for a list of dependencies and installation instructions. [**Documentation**](http://nortikin.github.io/sverchok/docs/main.html): If anything is unclear or missing in this document, please ask on the [Issue Tracker](https://github.com/nortikin/sverchok/issues).

Mesh and geometry programming involves combining basic elements such as: - Lists of indexed vectors representing coordinates (Sverchok uses zero-based indexing) - Lists of grouped indices representing edges and polygons - Matrices (user-friendly rotation-scale-location transformations) - Curves - Surfaces - Scalar and vector fields - Solids - Insolation and solar heating calculations ### Features With over 600 nodes for creating and manipulating geometry, combining these nodes enables you to: - Create parametric constructions - Easily adjust parameters using sliders and formulas - Utilize powerful nodes including: Profile parametric, UVconnect, Generative art, Mesh expression, Proportion edit, Wafel, Adaptive Polygons (tissue vectorized), Adaptive edges, ExecNodeMod, Vector Interpolation series, List manipulators, CSG Boolean, Bmesh operations, Bmesh properties, and more - Perform cross-sections, extrusions, and other modifications with flexible, parameterized, and vectorized node tools - Calculate areas, volumes, and perform other geometric analysis - Create or import CSV tables and custom formats - Work with vector/scalar fields—create them and visualize data - Perform solid modeling - Code custom nodes in Python using the Scripted node - Create custom 'addons' based on node layouts and integrate them into your workflow via Sverchok's 3D View panel - Access Blender's Python API (bpy) with specialized *Set* and *Get* nodes - Update Sverchok with a single click - Incorporate genetic algorithms into your workflow - Perform insolation/radiation calculations - Export SVG/DXF drawings directly from node trees - Exchange BREP/NURBS/IFC data - And much more! ### Installation Install Sverchok like any other Blender addon. - **Installation from Preferences** Download the Sverchok [archive (zip) from GitHub](https://github.com/nortikin/sverchok/archive/refs/heads/master.zip) - Do not unpack the archive after downloading — Blender will handle this - Mac OS users may need to [recompress the folder](https://support.apple.com/guide/mac-help/zip-and-unzip-files-and-folders-on-mac-mchlp2528/mac) if Safari automatically extracted and deleted the `.zip` - Go to Edit > Preferences > Add-ons - Click the `Install...` button - Browse to the zip file location, select it, and click "Install Add-on" - Blender will unpack the addon and present an option to enable it - Enable it by checking the box next to `Node: Sverchok` - Allow Blender a few seconds to complete the installation - When complete, Blender will display: - [x] Node: Sverchok By default, Blender (version 2.80 and above) will remember enabled addons for future sessions. - **Updating Sverchok** Use the `Check for new version` button in Sverchok's panel in the Node Editor (press `N` to open the panel) Click the `Update Sverchok` button Press F8 to reload addons—the new version number will appear in the N-panel - **Additional Dependencies** Sverchok provides many features out-of-the-box, but additional nodes and scripts utilize third-party libraries including: - scipy - marching cubes - geomdl - SciKit-image - shapely - circlify - freecadpython3lib Installation instructions for these dependencies are available on this [wiki page](https://github.com/nortikin/sverchok/wiki/Dependencies) ### Troubleshooting Installation Errors If installing from a release zip containing a folder named `sverchok-master.x.y.z`, rename it to `sverchok-master` since folder names with dots are invalid Python package names. If using releases from [here](https://github.com/nortikin/sverchok/releases), note that these versioned zips are intended for testing older Sverchok versions with legacy .blend files and Blender versions, not for initial installations. ##### Errors during installation or enabling If you encounter errors like: > `NameError: name 'nodes' is not defined` Exit and restart Blender, then enable Sverchok again. The addon may take up to 10 seconds to initialize depending on your system performance. ##### Other installation issues If Sverchok still fails to install, we've compiled troubleshooting solutions [here](http://nortikin.github.io/sverchok/docs/installation.html). Please report any new issues you encounter. Updating via the in-panel button may fail if you've renamed the installation folder. Follow [this guide](https://github.com/nortikin/sverchok/issues/669) for a bootstrap script solution. ### Contact and Credits **Homepage**: [nortikin.github.io/sverchok/](http://nortikin.github.io/sverchok/) **Authors**: - Alexander Nedovizin - Nikita Gorodetskiy - Linus Yng - Agustin Gimenez - Dealga McArdle - Konstantin Vorobiew - Ilya Portnov - Eleanor Howick - Walter Perdan - Marius Giurgi - Sergey Soluyanov - Ivan Prytov - Victor Doval - Dion Moult - Alessandro Zomparelli - Alex (aka Satabol) - @kevinsmia1939 **Email**: [email protected]
