Boolean Geometry

plugin boolean csg mesh modelling
Credits: igl@ETH Zurich, lichterloh. Also makes use of Eigen, CGAL and boost.


Boolean operations on groups of meshes



  • Easily use boolean operations (union, intersect, minus, xor) on 2 or more meshes to create new objects
  • Define a complex (recursive) "tree" of operations using helper nodes, see image below
  • Resolve feature eliminates intersecting faces of 2 or more meshes by adding new triangles with shared edges along intersections in all input meshes, useful e.g. for tetgen inputs
  • including helpfile{s}

This is a wrapper around boolean functions, i.e. CSG Tree, in libigl by the Interactive Geometry Lab @ ETH Zurich: http://libigl.github.io/libigl/


Source Code:

  • the source code for the vvvv plugin plus the c++ dll can be found in my addonpack fork:




All my code is MIT where possible; always happy about credit to digitalWannabe/lichterloh
All code from libigl is MPL2

don't know how to add a second image to a plugin page, so here's an example of a tree operation as mentioned above

Hmmm,I get 0 output from any of the Help patches. The Boolean Geometry doesn't output anything.

fibo: @microdee: AWS lambda has also other limitations like a 5 minute timeout, anyway serverless is really interesting.

microdee: @fibo: vvvv is delphi in its core, it just interacts with .NET with com visible objects under the hood. VL on the other hand...
