once awhile, i have /sci/entific questions; of which i am supposed to map/index a 256*256 square map into a sphere, but then the socalled mercator whatever geometric projection is goddamn conplicated and messy to write, and expensive fo write??? so what the fuck? somehow the content becomes bloated unlike the original supposed codes so i need something simpler and basic, that was used in the path so how the hell do i. do that???
