Shackled is the first general-purpose 3D rendering engine built entirely within smart contracts for the Ethereum blockchain.

To demonstrate the power of this technology, were creating an on-chain collection of 1024 3D generative art pieces. 

# The Shackled Genesis collection.

In each Genesis piece, youll find an exploration of depth, symmetry, hierarchy, perspective, and emergence. This is explained in detail in our blog.

The real magic happens when we pass those structures to the Shackled on-chain rendering engine; it brings them to life by computing a vibrant 3D render. Uniquely, Shackled doesnt require an off-chain or client-side renderer  it all happens on Ethereum. 3D art doesnt get more on-chain than this.

Shackled

Shackled is the first general-purpose 3D renderer running on the Ethereum blockchain. Each piece represents a leap forward in on-chain computer graphics, and the collection itself is an NFT first.

CHROMOSPHERES is a collection of 707 generative art NFTs capturing the brightest stars in the night sky. Each piece represents a real star, and is generated using astronomical and blockchain data.

All pieces are rendered post-mint by a supercomputer distributed across multiple data-centers.

The project is carbon negative, with all rendering and contract emissions offset 5X over.

# Utility

Chromospheres is Part 3 of Spectra Art's Dawn Trilogy. 

Collectors of the Dawn Trilogoy will be able to claim a Dawn Key and get exclusive benefits including presale access and discounts to future [Spectra.Art](https://spectra.art) projects.

Scheat (Chromosphere #9) is a piece from the third and final collection in Spectra's Dawn Trilogy. The Chromospheres collection comprises 707 pieces; each an artistic expression of a star from our night's sky. The rendering of each Chromosphere required the simulation of over half a trillion light rays, and each incorporates actual astronomical data from the star that it represents.

199X is Spectra.art's official PFP, our love letter to the 90s, and our most ambitious project yet.

In true Spectra fashion, the project is also an NFT first! Each Avatar is a 3D model rendered using our custom on-chain 3D graphics software, Shackled.

Every NFT includes:
1. A 3D model, so that in time you can use your Avatar in your favorite Metaverses and games.
2. A 2D on-chain render to use as a PFP.
3. A wireframe render, which you can use to give your PFP a unique look.

199X is Spectra's official PFP, a love letter to the 90s, and the first 3D PFP generated on-chain.
