MetalCanvas 0.1.0

🎉 Initial Release

MetalCanvas is a Swift library that provides an easy-to-use interface for rendering Metal shaders on macOS and iOS, inspired by glsl-canvas.

✨ Features

• 🎨 SwiftUI Integration - Native SwiftUI views for macOS and iOS
• ⚡ Automatic Shader Compilation - Built-in uniforms (time, resolution, mouse, date)
• ⏯️ Timer Controls - Play, pause, and reset animations
• 🖼️ Texture Support - Load and manage textures with TextureManager
• 🖱️ Mouse/Touch Tracking - Interactive shader effects with input tracking
• 📱 Cross-Platform - Works on both macOS and iOS
• 📚 DocC Documentation - Comprehensive API documentation
• 🧪 Swift Testing - Modern testing with Swift Testing framework

📦 Installation

Add MetalCanvas to your project using Swift Package Manager:

dependencies: [
    .package(url: "https://github.com/NakaokaRei/MetalCanvas", from: "0.1.0")
]

🚀 Getting Started

import MetalCanvas
import SwiftUI

struct ContentView: View {
    @State private var shaderCode: String? = """
        return float4(uv.x, uv.y, 0.5, 1.0);
    """
    
    var body: some View {
        MetalCanvasView(fragmentShader: $shaderCode)
    }
}

📱 Example Apps

The repository includes example apps for both macOS and iOS demonstrating various shader effects including:

• Gradient animations
• Plasma effects
• Mandelbrot fractals
• Voronoi patterns
• Texture rendering with sparkle effects
• Interactive mouse/touch tracking
