Mesh analysis methods for Mittsu.
Adds three methods:
Mittsu::Object3D#manifold?: Detects if a mesh is a single valid surface; i.e. it has no holes, and faces are consistently oriented.Mittsu::Object3D#solid?: Detects if the faces of a manifold mesh are correctly oriented, giving the mesh a sensible inside and outside.Mittsu::Face3#flip!: Flips the vertex order, and thus orientation of a particular face.
Ruby 3.1 or above, otherwise the same as for Mittsu itself.
Just install:
bundle add mittsu-mesh_analysis
Then require in your code:
require 'mittsu/mesh_analysis'
The methods above should then be available for use.
This code was originally written for Manyfold, supported by funding from NLNet and NGI Zero.
