词条 | ODE |
释义 | 【ODM】 ODM:Original Design Manufacture(原始设计厂商)的缩写,这是近年来兴起于国内IT业的概念,主要指的是,某些制造商设计出某产品后,在某些情况下会被其他的企业看中,要求配上后者的品牌名称来进行生产,又或有些较小的设计上的改动来生产,以减少自己的研制时间。那么前者就被成为后者的ODE。 【ODE常微分方程】 ODE:(Ordinary Differential Equations)常微分方程; ODE:(Open Development Environment)开放式开发环境; 【ODE 物理引擎】 ODE (Open Dynamic Engine) 是一个免费的具有工业品质的刚体动力学的库,一款优秀的开源物理引擎。它能很好地仿真现实环境中的可移动物体,它是快速,强健和 可移植的。而且它有内建的碰撞检测系统。3D游戏场景的编写主要使用了3D图形API-OpenGL 和ODE引擎等游戏仿真技术。 总共实现了以下基本的刚体物理运动游戏场景: (1)单摆运动:主要体现了球连接的具体使用。 (2)撞球:主要体现了碰撞的处理。 (3)汽车:主要体现了Hinge-2连接的使用。 (4)抛物线运动:主要体现了刚体方向和速度具体处理方法。 支持功能如下: · Rigid bodies with arbitrary mass distribution. · Joint types: ball-and-socket, hinge, slider (prismatic), hinge-2, fixed, angular motor, linear motor, universal. · Collision primitives: sphere, box, cylinder, capsule, plane, ray, and triangular mesh, convex. · Collision spaces: Quad tree, hash space, and simple. · Simulation method: The equations of motion are derived from a Lagrange multiplier velocity based model due to Trinkle/Stewart and Anitescu/Potra. · A first order integrator is being used. It's fast, but not accurate enough for quantitative engineering yet. Higher order integrators will come later. · Choice of time stepping methods: either the standard ``big matrix'' method or the newer iterative QuickStep method can be used. · Contact and friction model: This is based on the Dantzig LCP solver described by Baraff, although ODE implements a faster approximation to the Coloumb friction model. · Has a native C interface (even though ODE is mostly written in C++). · Has a C++ interface built on top of the C one. · Many unit tests, and more being written all the time. · Platform specific optimizations. · Other stuff I forgot to mention... 【ODE 方向选择刻蚀】 =orientation dependent etching |
