The conservation status of lion is threatened. I feel the same way about eating lion that I do about southern bluefin tuna; it's not sustainable, don't do it. I'd eat mountain lion or dog, but not lion or grey wolf. nb: wild

SSE4.1 added `blend` which does this for most data types. The lone exception is 32 bit integers for whatever reason, which wasn't added until AVX2.

Yup, unfortunately (but fortunately for my employer) there's no off the shelf tool that does this. Ultimately you just have to write a bunch of code. There does exist a standardized way to encode the data: MISB (Motion Imagery Standard

The N64's unified memory model had a pretty big asterisk though. The system had only 4kB for textures out of 4MB of total RAM. And textures are what uses the most memory in a lot of games.

The time to render an image is O(k log n), but the space required for any given pixel is O(log n). A BVH search is a recursive operation. Each pixel needs its own stack. Rasterizing triangles requires O(1) space. So you can cram 4096 or w

IANAL, but IMHO a soft 'deleted_at' timestamp along with a daily cron job that hard deletes everything with a deleted_at older than 24 hours would fall within the spirit of the law. I agree that just having a deleted_at timestamp

It's all well and good to have a library with fast sin/cos/tan functions, but always remember to cheat if you can. For instance, in a game, it's common to have a gun/spell or whatever that shoots enemies in a cone s
