it boggles the mind…
Sunday, July 6th, 2008I was reading the handy Apple OpenGL Programming Guide for Mac OS X when I found a joke right in the middle of the “Using Extensions to Optimize” section, of all places!
Note that OpenGL does not use DMA for a power-of-two texture target (
GL_TEXTURE_2D). So, unlike the rectangular texture, the power-of-two texture will incur one additional copy and performance won’t be quite as fast. The performance typically isn’t an issue because games, which are the applications most likely to use power-of-two textures, load textures at the start of a game or level and don’t upload textures in real time as often as applications that use rectangular textures, which usually play video or display images.
What a bunch of pranksters!
Wait a sec, you guys are serious?!

If this were an episode of Star Trek, now would be a “set phasers to kill” moment.
