Rendering drivers(solved)

Thanks for the help.

what is the calculation to find out? Are you serious?

log[base 2](size_of_texture) = exponent

you take (int)exponent and you got the lowest pow of 2

if exponent == (int)exponent then size_of_texture is already a pow of 2

if you don't want to lose details, you probably want to go to the highest pow of 2, which is (int)exponent +1

to find the closest, simply compare which is smaller, size_of_texture - 2^(int)exponent or 2^(int)(exponent+1) - size_of_texture

haha you evil one! you confused him more!

ok these are powers of 2 :

2,4,8,16,32,64,128,256,512,1024,2048,4096,8192,i_dont_think_you_will_be_using_larger_textures,..

never forget 1 is a pow2, and it works on even the oldest cards. It's stupid, but 1d texture and full color images use it

and I'm sorry, but logs are what, high school lvl or something? They are so easy, they are the inversion of powers and you just MUST know them if you,re gonna code... Especially 3d
