## Definition
Video Physics Definition视频物理一致性定义——在 AI 视频生成(如 Sora、Runway Gen-3通过显式约束确保衣物、头发、辅助行动器具轮椅、拐杖、假肢等元素的运动符合真实物理规律的技术方法。
## Problem
AI 视频生成模型在渲染动态元素时经常出现物理错误:
- 衣物如头巾Hijab运动不符合重力规律
- 轮椅轮胎与地面接触不一致(悬浮或穿入地面)
- 头发运动僵硬或不符合风向
- 辅助器具(拐杖)位置在连续帧之间漂移
## Solution: Physics Constraints
Inclusive Visuals Specialist 通过以下方式注入物理约束:
```typescript
// 示例:轮椅运动约束
"The wheelchair wheels maintain consistent contact with the pavement as she navigates the ramp."
"Her hijab drapes naturally over the shoulder as she walks, following the slight breeze."
```
### Three Levels of Physics Constraints
1. **Contact Consistency**:物体与接触面的持续接触(轮胎-地面、脚-地板)
2. **Drape/Gravity**软性物体的重力下垂Hijab下摆、宽松衣袖
3. **Motion Path**:连续帧之间的运动轨迹平滑性(拐杖支撑点的稳定移动)
