Rusterix is a fast software renderer for 2D and 3D triangles and lines. Its goals are to provide an easy and portable alternative to hardware rasterization for retro and low-poly games.
---
## How it works
Rusterix uses a multi-threaded, tile-based renderer and organizes 2D and 3D meshes into batches. It precomputes the bounding boxes and triangle edges for each batch during projection.
The main goal is to achieve a single rendering pass to maximize parallelization. The batching system makes this possible while also enabling grouping and optimizations for individual objects and content.
Because of these optimizations, Rusterix is not a general-purpose abstraction of a hardware rendering pipeline (for that, consider using the excellent [euc](https://github.com/zesterer/euc)). Instead, it features a custom pipeline specifically optimized for software rendering and operates within a fixed color space.
## Goals and Status
Once finished, you will be able to use Rusterix in several different ways:
* As a library to rasterize 2D and 3D meshes, WIP. See the `Cube` example.
* As a retro game engine with an editor for Doom style games. Programmable in Rust and an inbuild scripting system (TBD).
My goals for both of these use cases:
* Fast software based rendering.
* Procedural materials and particles for in game effects and content.
## Motivation
I use `rusterix` as the rendering engine for my [Eldiron](https://github.com/markusmoenig/Eldiron) project. But it makes sense to split it out into a re-usable library and engine.
