# Contrast Renderer
Contrast is a [web-gpu](https://gpuweb.github.io/gpuweb/) based 2D renderer written in [Rust](https://www.rust-lang.org/).
It renders planar [vector graphics](https://en.wikipedia.org/wiki/Vector_graphics) and can easily be integrated with other forward-rendering code.
Filling uses [implicit curves](https://en.wikipedia.org/wiki/Implicit_curve) and is resolution-independent, while stroking uses [parametric curves](https://en.wikipedia.org/wiki/Parametric_equation) and is approximated via polygon [tesselation](https://en.wikipedia.org/wiki/Tessellation_(computer_graphics)).
This way you can have non-diegetic, diegetic and spacial [GUI](https://en.wikipedia.org/wiki/Graphical_user_interface) elements on any flat plane:
- As classic 2D menu overlay on top of the 3D scene.
- As [HUD](https://en.wikipedia.org/wiki/Head-up_display) fixed relative to the camera movement but occluded by the 3D scene.
- As decals on walls or [holograms](https://en.wikipedia.org/wiki/Holography_in_fiction) hovering in the 3D scene.
To get started, checkout the [showcase example](examples/showcase/main.rs).
