Is there a standard in the computer graphics world to either use cartesian or polar coordinates?


I'm assuming there are some operations that are easier to do in Cartesian and others that are easy to do in Polar. In graphics, do we usually store a vector in memory in both representations for faster operations?


Do the choice of coordinate system have an effect on the data format we choose to store coordinates in (e.g., do half floats work for one but wouldn't work as well for another?)
