1. 刚体变换(Rigid Body Transformations) 在欧几里得空间中运动的粒子的运动描述是通过给出粒子在每一时刻相对于惯性笛卡尔坐标系的位置来实现的。具体来说,我们选择一组三个正交坐标轴,使用三维数组(x,y,z)∈R3 指定粒子的位置,其中每个坐标表示粒子位置在相应坐标轴上的投影。粒子的轨迹由参数化曲线 p(t)=(x...
I am trying to move a rigid body in a straight line while it continuously rotates about its centroid. Is it possible to achieve the above motion without writing a script? I presume the rotation should be about the local coord system which is the centroid of the car and the translation sho...

These forms are used as a basis for developing a rotational treatment of energy and power, and for dealing with impact situations that involve rotation. When a rigid body possesses linear and rotational motion, the description of its motion can be simplified by choosing the origin to be in ...
Angular Factor It can affect the rotation speed change of the rigidbody in each axis. The larger the value, the faster the rigidbody rotates. For the API interface of RigidBody, please refer to RigidBody3D. RigidBody Motion There are several ways to make a rigidbody move: ...
rigid body (redirected fromRigid body motion) An idealized extended solid whose size and shape are definitely fixed and remain unaltered when forces are applied. Treatment of the motion of a rigid body in terms of Newton's laws of motion leads to an understanding of certain important aspects of...
5 力旋量和互易旋量(Wrenches and Reciprocal Screws) 在这一节中,我们考虑作用在刚体上的力(forces)和力矩(moments),并以此来介绍旋量系统和互易旋量的概念。 5.1 力旋量(Wrenches) 作用在刚体上的广义力由作用在一点上的线性分量(纯力pure force)和角分量(纯力矩pure moment)组成。我们可以把这个广义力表示为R6...
Rigid-Body Motion(旋转变换\Screw motion\Spatial velocities\Force) 摘要:SE(3)=T=[Rp01]SE(3)=T=[Rp01]SE(3)是一个4X4的矩阵.它具有的性质如下: 1. 两个SE(3)的乘积仍是一个SE(3) 2. SE(3)的逆: $$T^{ 1}=\begin{bmatrix}R^T& R^Tp\\0&1\en阅读全文 ...
