No IPFS, no hosting, no any shenanigans - fully on-chain animated 3D art - just a separate renderer contract with some JavaScript.
Nothing is pre-rendered - no mp4 files, no gifs - everything happens in your browser - on the fly.
Due to on-chain nature, minting will immediately call tokenURI function which will in turn immediately call the renderer contract.
Result, you will immediately see the art after minting.
