I will be presenting the basics of 3D rendering with Metal in Swift on Nov. 4th at Realm! http://meetu.ps/2BxpX6 pic.twitter.com/jnEvPY9Hjk

@warrenm Hi, was wondering what are the options to create texture from .png with few mipmap levels? So far I used only mipmap level 0
@haawa799 Although you can generate them on the CPU with CG, the best way is to use a blit command encoder. See generateMipmapsForTexture:

@warrenm Oops, I just made a project in which I generate mipmap layers using Metal kernel functions xD Check it out!http://tinyurl.com/otv3gns -
@haawa799 Haha, impeccable timing! Now that you have that, I’d be really curious to know whether/how much faster it is to use blitting :) -
@warrenm Just found out that my manual mipmap generator is 100x slower then generateMipmapsForTexture :( Good experience tho. -
@haawa799 Yeah, that’s a great point of reference. I’ll have to write a quick article on mipmap generation… -
@warrenm Just found out, that I made an error with calculations, my method is 4x slower, not 100x. Now I will sleep better :) -
@haawa799 That seems more plausible
