about

Boolean operations on groups of meshes

  
   

Features:

  • 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:

https://github.com/digitalwannabe/vvvv-sdk/tree/develop/vvvv45/addonpack/src/nodes/plugins/3d/3dConstructiveSolidGeometryTree

   

Licenses:

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

          
     

Changelog:

v1.0 :

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

Great!

thank you :) it's again from the lib i've shown you....

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

@letoast let me know which version you are using and i'll check!

..this doesn't work, does it? Tried it in 35.8 x86 & 64bit. There's no output from Boolean Geometry Node, Ex9 & DX11. Same with help patches.. help!

same error on 35.18 and 35.12

seems not working anymore in recent vvvv version

I have tried to use the digital wannabe nodes, but they don't produce any output. Has anyone got them to work? Thank you

ravazquez: @levi not sure bout the ImagePack, but I believe VL.OpenCV should give you the same tools and should work with beta just fine
