What are the best math for understand edge loops 3D models?

To understand edge loops in 3D models, basic mesh topology and graph theory fundamentals are most helpful—they explain how edges connect into loops and shape a model’s structure. Mesh topology clarifies how edge loops follow a model’s form (e.g., around a character’s eye) to support smooth deformation. Graph theory breaks down edges as connected paths, which is key for editing, UV mapping, or rigging. Start with simple shapes (like a Blender cube) and adjust edge loops—hands-on practice reinforces these math concepts without heavy theory.
