Mesh Boolean (plugin)

Introduction

This plugin can be used to perform Boolean operations on meshes (also called CSG = Constructive Solid Geometry).

It is based on the libigl library.

Procedure

Its usage is pretty straightforward:

• select two meshes (meshes should be ideally closed, otherwise the output might be wrong)
• click on the plugin icon (or the equivalent entry in the 'Plugins' menu: 'Plugins > Mesh Boolean Operations')
• when the plugin dialog appears (see above):
  • assign each mesh to a role (A or B)
  • then select the operation to apply:
    • union: A + B
    • difference (symmetric or not): A - B
    • intersection: A n B

The plugin will create a new mesh corresponding to the operation output:

This plugin is very similar to the Cork plugin. It is however slower but supposedly more robust.
