Mittsu: Mesh Analysis

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.

Requirements

Ruby 3.1 or above, otherwise the same as for Mittsu itself.

Usage

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.
