Vello CPU

CPU-based renderer

This crate implements the CPU-based renderer for Vello. It is optimized for running on lower-end GPUs or CPU-only environments, leveraging parallelism and SIMD acceleration where possible.

Features

• Fully CPU-based path rendering pipeline
• SIMD and multithreading optimizations
• Fine rasterization and antialiasing techniques

Usage

This crate serves as a standalone renderer or as a fallback when GPU resources are constrained.

Minimum supported Rust Version (MSRV)

This version of Vello CPU has been verified to compile with Rust 1.85 and later.

Future versions of Vello CPU might increase the Rust version requirement. It will not be treated as a breaking change and as such can even happen with small patch releases.

As time has passed, some of Vello CPU‘s dependencies could have released versions with a higher Rust requirement. If you encounter a compilation issue due to a dependency and don’t want to upgrade your Rust toolchain, then you could downgrade the dependency.

# Use the problematic dependency's name and version
cargo update -p package_name --precise 0.1.1
