Delaunay Flow - Geometric Live Desktop Wallpaper

Description

Delaunay Flow is a visually striking and interactive live desktop wallpaper that uses Delaunay Triangulation to generate and color a field of triangles across your screen. Each triangle's color is determined by its vertical position, creating a smooth gradient that flows from top to bottom.

Features

• Dynamic triangle mesh generated via Constrained Delaunay Triangulation
• Smooth vertical color gradient with multiple color stops
• Fully customizable via settings.json
• High-performance OpenGL rendering
• Built in C++ with real-time responsiveness

Requirements

• OS: Windows 10/11
• GPU: OpenGL-compatible
• Compiler: Visual Studio 2022 (recommended)

Installation

1. Download: Get the latest version of Delaunay Flow from the Releases page.
2. Launch: Run Delaunay-Flow.exe to enjoy your new live wallpaper.

Building

1. Clone the repository:

   git clone https://github.com/erfan-ops/Delaunay-Flow.git 
   cd Delaunay-Flow

2. Generate and build using CMake (choose one):

   Release build:

   cmake --preset vs-release
   cmake --build --preset release

   Debug build:

   cmake --preset vs-debug
   cmake --build --preset debug

3. Run the executable from the output directory:

   • Release: build/Release/Delaunay-Flow.exe
   • Debug: build/Debug/Delaunay-Flow.exe

Configuration

Customize the wallpaper by editing settings.json:

{
    "fps": 120,
    "vsync": false,

    "background-colors": [
        [ 0.28, 0.09, 0.65, 1 ],

    "mouse-barrier": {
        "draw": true,
        "radius": 0.25,
        "color": [ 0.2, 0.05, 0.7, 0.3 ],
        "blur": 25
    },

    "offset-bounds": 0.3,

    "MSAA": 4
}

• fps: Target frames per second.
• vsync: uses vertical synchronization.
• background-colors: Gradient stops (RGBA format) interpolated based on triangle Y position.
• stars: Star configurations (speed, count, radius, color, etc.).
• edges: Configuration for drawing triangle edges.
• interaction: enables the mouse to move the stars away.
• mouse-barrier: Configuration for drawing a glow around the mouse.
• offset-bounds: The screen offset which enables the stars to go pass though screen boundaries.
• MSAA: enables multi-sample anti-aliasing
