It's kind of weird to me that GPUs don't have planar textures now, I guess... maybe it shouldn't be weird to me, but it is?

@cmuratori Like, everything (at least in OpenGL) still requires going through an interleaving path, AFAICT, but I don't really get why.1 reply 0 retweets 0 likes -

@cmuratori Wouldn't it be more efficient to always be planar? Or are tex units totally on the interleaved path, and there's no going back?1 reply 0 retweets 0 likes -

@cmuratori Because GPU cores now always operate "planar" now, don't they? Ie., SIMD lanes are 16 or 32 wide R-R-R... etc., not R-G-B-A...3 replies 0 retweets 0 likes -

@cmuratori So it just seems weird that textures are still all about interleaving. What am I missing?4 replies 0 retweets 0 likes -

@cmuratori filtering is more efficient with swizzled textures, no?1 reply 0 retweets 0 likes -

@kamidphish Swizzling != interleaving - they're different!2 replies 0 retweets 0 likes -

@cmuratori I read planar as linear. That was my confusion.1 reply 0 retweets 0 likes
@kamidphish Roger that - yeah.
