# Wayland Shader Demo

A lightweight, interactive shader playground built with **C++**, **Wayland**, and **OpenGL ES 2.0**.

## Features

### 🌌 Interactive Fractals
*   **Deep Zoom Mandelbrot**: Features an **Infinite Zoom** engine using Perturbation Theory (CPU computes 128-bit reference orbit, GPU renders delta). Zoom level up to $10^{34}$!
*   **Customizable**: Use the sidebar sliders to adjust the **Exponent** (create "Multibrots") and morph the set with **Julia** offsets ($C_{real}$, $C_{imag}$).
*   **Fractal Explorer**: Standard fractal shaders included.

### 🧪 Physics & Simulations
*   **Fluid Dynamics**: Real-time interactive fluid simulation (mouse drag to swirl).
*   **Reaction Diffusion**: "Living" texture simulation (Gray-Scott model).
*   **Double Pendulum**: Chaotic physics visualization.

### 🎨 Visuals
*   **Plasma & Tunnel**: Classic demoscene effects.
*   **Sidebar UI**: Custom immediate-mode GUI with embedded font rendering.

## Controls
*   **Left Click**: Select shader from sidebar.
*   **Scroll**: Zoom (Mandelbrot).
*   **Drag (Left Click)**: Pan view / Interact with Fluid / Adjust Sliders.

## Build & Run
```bash
make
./shader-demo
```

## Dependencies
