我們用 100 萬顆粒子，組成各式各樣的形體，依序是
- 大衛像肖像
- 沉思者
- 蒙娜麗莎的微笑
- 大碗島的星期天下午
- 大翅鯨
- 地球
- 土星
- 太陽
- 作者海報
其中粒子的動態是透過 Second Order Dynamics 決定的
全部手寫，沒有使用任何 ParticleSystem
完整執行流程:
- Mesh sampling in compute shader (從 mesh 上 sample 100 萬個粒子的位置)
- Second order dynamics in compute shader (決定粒子移動的動態)
- Draw particles (畫出粒子)

Enjoy!

Feature List:
1. Mesh Sampling (compute shader).
2. Second Order Dynamics (compute shader).
3. Lit shader with GPU instancing support.
