The kinematics of rigid body is the motion analysis without considering any external forces acting on a rigid body, which is actually the foundation of the dynamics of rigid bodies. This chapter firstly presents the representation method of the position and orientation of rigid bodies using both ...
然后可以使用body.getLinearVelocity() + deltaLinearVelocity计算预测的线速度,而预测的角速度可以使用body.getAngularVelocity() + deltaAngularVelocity来计算。如果需要,可以使用body.setLinearVelocity(body.getLinearVelocity() + deltaLinearVelocity)和body.setAngularVelocity(body.getAngularVelocity() + deltaAngularVelocit...
Part I. 无约束刚体动力学 Unconstrained Rigid Body Dynamics 1. 模拟基础 Simulation Basics 这部分课程笔记旨在全面实施刚体运动。在本节中,我们将展示模拟刚体运动的基本结构。在第 2 节中,我们将定义实现刚体模拟器所需的术语、概念和方程。在此之后,我们将给出一些代码来实际实现我们需要的方程。我们将使用的一...
and rotational motion of real bodies without the necessity of considering the complications involved when changes in size and shape occur. Many of the principles used to treat the motion of rigid bodies apply in good approximation to the motion of real elastic solids.SeeRigid-body dynamics ...
Rigid Body Dynamics 在本章中,我们将介绍一些主题,一旦您熟悉了设置基本的刚体模拟世界,这些主题也很重要。 Velocity 刚体的运动分为线性和角速度(linear and angular velocity)分量。在仿真过程中,PhysX将根据重力(gravity)、其他施加的力(other applied forces)和扭矩(torques)以及各种约束(如碰撞或joint)来修改物体...
Rigid Body Dynamics In this chapter we cover a number of topics that are also important to understand once you are comfortable with setting up a basic rigid body simulation world. Velocity¶ A rigid body's motion is separated into linear and angular velocity components. During simulation, ...
For two-dimensional rigid body dynamics problems, the body experiences motion in one plane, due to forces acting in that plane. A general rigid body subjected to arbitrary forces in two dimensions is shown below. The full set of scalar equations describing the motion of the body are: Where:...
do not exist in the real world – even the hardest materials deform at least a very small amount when some force is applied to them – but the rigid body is a useful model of physics for game developers that simplifies the study of the dynamics of solids where we can neglect deformations...
