The anglr package is about data structures and 3D visualization.

Key aspects of data structures are:

• mesh-topology with a common vertex-pool for connected shapes.
• line segments.
• path-based geometry.
• triangulated surfaces.
• high-quality triangulations, meshes.
• relational vs. structural forms.
