摘要： To now,the engine still has limits: It can't describe the way objects rotate. Robust general-purpose collision detection system Center of Mass \[p_{co 阅读全文

摘要： Initially we’ll look at the most common hard constraint—collisions and contact between objects.All the engines we’re building in this book treat hard 阅读全文

摘要： One of the most useful forces we can create for our engine is a spring force. Although springs have an obvious use in driving games (for simulating th 阅读全文

摘要： D’ALEMBERT’S PRINCIPLE For particles D’Alembert’s principle implies that, if we have a set of forces acting on an object, we can replace all those for 阅读全文

摘要： Ballistics One of the most common applications of physics simulation in games is to model ballistics. This has been the case for two decades, predatin 阅读全文

摘要： A PARTICLE The first law The problem arises because the processor that performs the physics calculations isn’t completely accurate. This inaccuracy ca 阅读全文
