We are implementing LOD using the threejs mesh simplifier as discussed in topic virtually geometry where we crunched down meshes to its simple poly proportional to the distance from the camera, this is how we are able to load large scale assets in threejs. It is part of threejs samples mesh simplifier is a very useful feature combine with mipmapping as demonstrated in this image:
The method using the mesh simplifier is pretty straightforward where you just reduce the mesh vertices then reapply back the texture, unlike LOD where you have 3 to 5 different mesh that adds to the gltf file size, simplifier only have the original mesh.
With LOD methods, massive maps feel completely normal. No more freezing or lag, just exploring huge worlds smoothly. You can wander around different places at the same time, explore virtual markets, parks, go racing, or go on adventures. Imagine owning your own apartment or flat in all of this. That would be so cool! Honestly, three.js makes it feel like virtual life could be just as real as real life.
Imagine what you can achieve all because of LOD, with the sheer scale of an open-world map running smoothly in your browser using Three.js. Explore vast landscapes, roam through cities, parks, and markets, or dive into thrilling adventures, all seamlessly and without limits.
