Blitblox is the first on-chain 3D NFT that contains all the glTF data in its contract. Blitbox turns the original 32x32 two-dimensional images of Blitmap (and Flipmap) into a 3D asset that is stored in a decentralized manner on the Ethereum blockchain. Because Blitmap artwork is in the public domain with the CC0 license, creators like myself have the ability to extend the original artwork and contracts in exciting new ways. If you’re new to web3 or not familiar with a lot of the terminology in the last few sentences hopefully this post clears some of it up. I’ll start with high level concepts about 3D NFTs then dive into the contract itself.
