Rigid Bodies

Our living environment is stuffed with rigid objects.

✅ rigid:物体很硬,因此不考虑形变。

P6

Rigid Body Simulation

The goal of simulation is to update the state variable s[k] over time.

P7

Rigid Body Motion

If a rigid body cannot deform, its motion consists of two parts: translation and rotation.

✅reference:参考状态,无平移,无旋转此时物体中心点在原点上,x 轴向左,y 轴用上z 轴向前。
当前状态:旋转为R,平移为T. 那么物体上任意点的位置为:
x=Rx+T
刚体模拟:已知当前时刻的状态和受到的力,求下一时刻的状态。
