Crate astrelis_geometry 

Astrelis Geometry - Customizable 2D geometry rendering

This crate provides:

• Path and shape primitives for 2D vector graphics
• Tessellation (converting paths/shapes to triangle meshes)
• Style system (strokes, fills, gradients)
• GPU-accelerated rendering with instancing
• Mathematical charting (optional “chart” feature)

Example

use astrelis_geometry::*;

// Create a geometry renderer
let mut renderer = GeometryRenderer::new(context);

// Draw shapes
let style = Style::fill(Paint::solid(Color::RED));
renderer.draw_shape(&Shape::circle(Vec2::new(100.0, 100.0), 50.0), &style);

// Draw custom paths
let path = PathBuilder::new()
    .move_to(Vec2::new(0.0, 0.0))
    .line_to(Vec2::new(100.0, 0.0))
    .quad_to(Vec2::new(150.0, 50.0), Vec2::new(100.0, 100.0))
    .close()
    .build();
renderer.draw_path(&path, &style);

// Render to a pass
renderer.render(&mut pass, viewport);
