if(GLM_CONFIG_CLIP_CONTROL & GLM_CLIP_CONTROL_LH_BIT) return lookAtLH(eye, center, up); else return lookAtRH(eye, center, up); } 这里其实会先判断是左手坐标系,和右手坐标系,因为左手坐标系和右手坐标系z轴的指向不同,因而最终的运算结果也有差异,OpenGL是右手坐标系,因此我们来看看lookAtRH函数 ...

虽然代码很好,如果OP不知道`lookAt`是如何工作的以及参数意味着什么,这对他来说根本不能理解任何东西.例如*"交叉乘积给出平行四边形的面积,对于非垂直单位长度向量<1.0" - 完全不相关,甚至超过它给出与两个操作数正交的向量(其长度是平行四边形的面积) )这是我们在这里需要的几何属性.但是好吧,最后一部分从贬低...
