# 설치 가이드

1. 코드 내려받기

git clone https://github.com/cortiz2894/flow-shield-effect

깃허브에서 프로젝트 코드 전체를 내 컴퓨터로 내려받습니다.

cd flow-shield-effect

방금 내려받은 프로젝트 폴더 안으로 이동합니다.

2. Node.js

쉬움 추천

사전 준비물

Git GitHub에서 프로젝트 코드를 내려받으려면 필요합니다.
Node.js npm 명령어를 쓰려면 Node.js가 설치되어 있어야 합니다. LTS(장기지원) 버전을 추천합니다.

pnpm install

package.json에 명시된 라이브러리들을 내려받아 설치합니다.

pnpm dev

개발/실행 서버를 켭니다.

✅ 명령어 실행 후 터미널에 나타나는 주소(보통 http://localhost:3000 형태)를 브라우저에서 열어보세요.

# Force Shield VFX

A real-time force shield effect built with React Three Fiber, Three.js, and custom GLSL shaders.
This repository is a free open-source resource for the creative development community.

It includes a fully interactive **3D Playground** to explore every parameter of the shield in real time — hex grid, hit impacts, life system, reveal animation, bloom, and more.

## ✨ What is this?

**Force Shield VFX** is a production-quality WebGL shield effect built entirely with custom vertex and fragment shaders.
It is designed as a learning resource and a starting point for similar VFX in interactive 3D projects.

Key highlights:

- Fully parametric — every visual property exposed via GUI
- Written in clean, well-commented GLSL
- Organized codebase: shaders, controls, and constants are split into separate files
- Two ready-to-use scene presets (Default and Droideka)
- Zero external shader libraries — everything is hand-written

---

## 🛡 Shield Features

### Visual
- **Hex grid** — tri-planar projection with cube-face selection and seam fade
- **Fresnel glow** — edge highlight driven by view angle
- **Flow noise** — animated surface disturbance using layered simplex noise
- **Cell flash** — per-hex random flicker
- **Bottom fade** — configurable gradient that dissolves the shield toward the ground
- **Life color** — shield shifts from its base color to red as health depletes

### Hit System
- **Ring buffer** — up to 6 simultaneous hit impacts tracked in parallel
- **Expanding ring** — noisy geodesic wavefront that radiates from the impact point
- **Hex highlight zone** — cells near the impact flash on contact
- **Life damage** — each hit reduces shield health by a configurable percentage
- **Reset** — one-click life restore via GUI

### Reveal Animation
- **Noise-based dissolve** — shield materializes and dematerializes through a simplex noise mask
- **Edge glow** — emissive border traces the dissolve front
- **Manual mode** — scrub the reveal progress manually via slider

### Post-processing
- **Bloom** — luminance-threshold bloom with mipmap blur
- **Film noise** — configurable grain with blend mode and opacity controls

---

## 🎮 3D Playground

A built-in development environment for exploring the effect in context.

### Scene Controls
- Orbit camera with auto-rotate, damping, and FOV
- Real-time ambient and directional light manipulation
- HDRI environment with background blur and intensity
- Infinite grid floor with reflective plane
- GLB model import for custom scene compositions

### Presets
| Preset | Description |
|--------|-------------|
| **Default** | Floating shield sphere in a neutral scene |
| **Droideka** | Shield wrapped around a Star Wars Droideka model |

Switching presets instantly applies a curated set of shader, lighting, and scene values.
