If you know what a complex number is, a quaternion is fairly similar. It is essentially a complex number with 3 imaginary components instead of one. I wanted to plot quaternions on a 2D graph to make visualizing quaternion equations easier to understand. http://elijah.mirecki.com/blog/27/ Thu, 12 Dec 2013 00:37:48 +0000 http://elijah.mirecki.com/blog/27/ So, I was just thinking about how C++ is really stored in memory, and realized that private class variables are not private at all, in reality. When a class is stored in memory, all of the member variables are simply stored in a big blob of data. So in theory, if you simply typecast a pointer to a class to another type, pointer arithmetic could be done to access any member variable.
