【摘要】 本文将刚体力学与计算机技术相结合,介绍了对刚体的物理运动进行实时模拟的方法和步骤。通过Vector类封装的与向量运算相关的成员函数和操作符,对顶点对顶点、顶点对边这两种接触类型的碰撞侦测进行了探讨和研究,运用动量及动量矩定理计算了碰撞刚体间的实际冲量公式,建立了刚体碰撞响应模型,从而实现对2D刚体碰撞的实时模拟。更多还原

【Abstract】 The paper combine geostatics with computer technology, state the method and step of physical movement simulation of rigid body in real time. Based on the member function and operating symbol about vector operation that vector class encapsulate, the paper makes an inquiry into the collision detection completely of two kinds of contact style. Namely, vertex and vertex, vertex and edge. It calculates actual impulse formula of rigid bodies with collision by momentum and angular momentum theorem and builds Response model that the collision of 2D rigid bodies is simulated really based on it.更多还原
