执行一个简单的C++四元类被称为“蹲”。根据Ken Shoemake的开创性论文普及，四元数代表了约一个轴旋转。“蹲”可以通过**=运营商连接在一起，并转换之间来回变换矩阵。实现还包括由Don Hatch的三维矢量宏库-Implementation of a simple C++ quaternion class called "Squat". Popularized by a seminal paper by Ken Shoemake, a quaternion represents a rotation about an axis.　Squats can be concatenated together via the* and*= operators and converted back and forth between transformation matrices. Implementation also includes a wonderful 3D vector macro library by Don Hatch
