How to speed up model loading and how to reduce model size

[Mugen87]

@11141 Please use the search a bit more before posting new topics. Reducing the download size of asset was already discussed multiple times. In context of glTF, this answer is also useful:

Is it possible to reduce memory consumption with new glTF format?

@EtagiBI typically the RAM available to your CPU is a relatively small aspect of a WebGL scene’s performance. Mostly you’ll use that memory while loading the model, and yes — glTF is designed to be very efficient to load. The mesh data is already in a binary buffer that can be uploaded directly to the GPU without copying it anywhere. The implementation of THREE.GLTFLoader is not entirely “in place”, but should still be pretty good. Compare that to text-based formats like OBJ, where every charact…
