A lot of the numeric portions utilized in video games (apart from integers for counting or indexing objects) are single-precision floating level. That is IEEE format, which permits for numbers as massive as 1e38 and as small as 1e-38.
Such a big dynamic vary is sensible within the context through which the IEEE floating-point customary was outlined: roughly talking, for scientists, who routinely take care of very massive and really small numbers.
Intuitively, video games appear unlikely to need to take care of such a variety. Say you measure distance in meters. Draw distance perhaps a number of kilometers? Smallest objects a number of millimeters? Granted that multiplying numbers can quickly take them out of the unique vary, it could appear adequate to have a dynamic vary like 1e8 to 1e-6, whereupon extra of the bits might’ve been used for larger precision.
However perhaps I’m lacking one thing in regards to the information and calculations routinely utilized in video games.
What kind of dynamic vary do video games truly use?
