Three.js is great for learning WebGL and rendering a single model in AR, but scaling up is painful. Developers must implement batching, instancing and memory management on their own, and even simple upgrades can break existing code. Wonderland Engine is a compiled WebAssembly engine with a user‑friendly editor that automatically optimizes geometry, materials and textures. For a simple product viewer, Three.js is perfectly adequate; for interactive games, VR worlds or scenes with thousands of objects, Wonderland Engine is the right tool.
Why upgrade from Three.js?
Engine vs. framework
Three.js provides low‑level primitives; advanced rendering techniques such as draw‑call batching and lod management must be implemented manually. Wonderland Engine automatically optimizes scenes and manages thousands of objects for you.
Visual editor
Wonderland Engine ships with a native editor that artists and developers can use collaboratively, eliminating the bottleneck of code‑only scene creation.
Cross‑browser performance
Three.js suffers from Safari and WebGL API limitations, and keeping up with API changes breaks code. Wonderland Engine uses WebAssembly to maximize speed and maintains backwards compatibility.
Optimized loading
Wonderland Engine packs assets into an efficient binary format with automatic compression for rapid loading, unlike Three.js where you must manually tune GLTF and textures.
