MessyPoly 3D Handbook
Build 3D assets that are lighter by design.
A practical, technically rigorous field manual for understanding geometry, diagnosing heavy models, and shipping visually faithful 3D assets across the web, games, XR, and real-time tools.
Learning paths
Start where you are.
Each section moves from durable concepts to production decisions you can apply to a real asset.
Foundations

02 · Make it fastPerformance
How geometry, textures, draw calls, and delivery choices affect real-world speed.
03 · Go deeperMesh Science
Simplification algorithms, error metrics, topology, and visual-fidelity measurement.
04 · Ship anywherePlatforms
Practical optimization targets for three.js, Unity, Unreal, Godot, Blender, WebXR, and mobile.
05 · Do the workField Guides
Repeatable recipes for shrinking, diagnosing, and preparing real assets for production.
