This crate implements a hybrid CPU/GPU renderer for Vello. It offloads fine rasterization and other GPU-suited tasks while keeping core path processing on the CPU, making it a balanced solution for a variety of hardware.

Features

• Hybrid rendering approach with CPU-based tiling and GPU-accelerated fine rasterization
• Efficient path processing with sparse strip representation
• Designed for performance across different hardware capabilities

Usage

This crate serves as an optimized hybrid rendering engine, leveraging both CPU and GPU where appropriate.

Feature Flags

• wgpu (enabled by default): Enables the GPU rendering backend via wgpu and includes the required sparse shaders.
• wgpu_default (enabled by default): Enables wgpu with its default hardware backends (such as Vulkan, Metal, and DX12).
• webgl: Enables the WebGL rendering backend for browser support, using GLSL shaders for compatibility.

If you need to customize the set of enabled wgpu features, disable this crate's default features then enable its wgpu feature. You can then depend on wgpu directly, setting the specific features you require. Don't forget to also disable wgpu's default features.

Minimum supported Rust Version (MSRV)

This version of Vello Hybrid has been verified to compile with Rust 1.88 and later.

Future versions of Vello Hybrid 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.

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