The svg-3d-renderengine-for-nfts from a6b8

A 3D Renderengine which is perfectly suited for on-chain / composable SVGs.

This project is heavily inspired by LoneCoders Code-It-Yourself! 3D Graphics Engine Youtube Series. Which inspired me to build my own 3D SVG Renderengine.

The Goal
is to generate a SVG with a 3D representation on chain with less data as possible. A solidity smart contract has a limit of 24 kb. Which means the engine should have less then 10-15kb (currently 20-25kb). BUT a javascript version can also generate a 3D SVG off-chain and send the points to the contract.

Why not use an existing Renderengine? First of all, it´s fun do it by my own! Second it make a lot of sense to think about every line of code for the new purpose of on-chain svg.

Why do you start with javascript? Well, for development i need a template for comparison anyway. Plus a web interface is the perfect fit for this type of project.

But solidity have no floating numbers. Yes! This should be a good starting point

What are the reduction strategies besides traditional 3D Renderengines have?

CSG Operations for recursivly merging polygons together.
Reduce faces by grouping into grey areas.
...

How did you start? This project is heavily inspired by LoneCoder´s Code-It-Yourself! 3D Graphics Engine Youtube Series. Which inspired me to build my own SVG version.
