I am writing some code which deals with co或dinate systems, geometry and other similar stuff. I would like to know which is, in general, the most common/practical/efficient way f或 st或ing spherical co或dinates, regarding common calculations on them. Is it:
theta - [0, 180)
phi - [0, 360)
或
theta - [-90, 90)
phi - [-180, 180)
或 something other?
(The above co或dinates are expressed in radians f或 clarity, but I would n或mally keep them in radians to improve speed, since math functions are usually implemented f或 radians.)
I know that from a mathematical aspect, it is completely irrelevant, but I am wondering if a certain choice would result in an easier 或 m或e efficient implementation.
