What it does
Position and rotation prediction for game state extrapolation. Supports multiple algorithms from simple linear extrapolation to Kalman filtering.
Key Classes
| Class | Description |

Predicts future rotations from historical data |
Algorithms
| Algorithm | Description |
|---|---|

Adaptive Mode
PositionPredictor with algorithm: ADAPTIVE automatically switches algorithms based on prediction error:
- Error > 2× threshold → Kalman
- Error > threshold → Verlet
- Otherwise → Cubic
