## What it is
Forma is an experimental, thoroughly parallelized vector-graphics renderer written in Rust with both CPU (SIMD + Rayon) and GPU (wgpu/WebGPU) back-ends. It implements a simple 4-stage pipeline (curve flattening, rasterization, sorting, painting) with a focus on portability, performance, and minimal dependencies.

## Use cases
- render vector graphics in Rust
- rasterize bezier curves to pixels
- GPU-accelerated 2D rendering
- software rasterizer for vector paths
- embed a vector renderer in a cross-platform app
- render vector graphics on mobile and desktop

## When to choose
- you need a portable Rust vector renderer across Fuchsia, Linux, macOS, Windows, Android, and iOS
- you want both CPU and GPU rendering back-ends
- performance matters and you want a parallelized rasterization pipeline
- you want a small dependency footprint focused purely on vector graphics

## When to avoid
- you need a stable, production-mature renderer - the project is explicitly experimental
- you need full 2D graphics features beyond vector rendering (text layout, images, effects)
- you need an actively maintained project - the latest release dates to mid-2023
- you prefer a widely adopted renderer like Skia or Vello with larger ecosystems
