rough_vello

This crate is an adapter crate between roughr and vello crates. Converts from roughr drawing primitives to vello's Scene types. Also has convenience traits for drawing onto vello scenes. For more detailed information you can check roughr crate.

Below examples are output of rough_vello adapter.

📦 Cargo.toml

[dependencies]
rough_vello = "0.16"

🧩 Vello Compatibility

rough_vello exposes vello::Scene in its public API, so your project must use the same vello version as rough_vello.

🔧 Example

Rust Logo

use rough_vello::VelloGenerator;
use vello::Scene;
use palette::Srgba;
use roughr::core::{FillStyle, OptionsBuilder};

let options = OptionsBuilder::default()
    .stroke(Srgba::from_components((114u8, 87u8, 82u8, 255u8)).into_format())
    .fill(Srgba::from_components((254u8, 246u8, 201u8, 255)).into_format())
    .fill_style(FillStyle::Hachure)
    .fill_weight(1.0)
    .bowing(0.8)
    .build()
    .unwrap();

let generator = VelloGenerator::new(options);
let rust_logo_svg_path = "..."; // SVG path data for the Rust logo
let rust_logo_drawing = generator.path::<f32>(rust_logo_svg_path);

let mut scene = Scene::new();
rust_logo_drawing.draw(&mut scene);

🔌 Integration

Windowing

rough_vello only produces vello::Scenes, so it works with any setup that can render vello scenes. The examples open a plain winit window and render with vello::util::RenderContext; see examples/common/mod.rs.

Bevy Integration

For Bevy, bevy_vello can render vello scenes. Pick a bevy_vello release that depends on the same vello version as rough_vello (currently vello 0.10), otherwise the Scene types will not match.
