QDAA

Implements really simple antialiasing via *super-sampling*, also known as SSAA. ## Huh? Antialiasing is often implemented via "FXAA", "TAA", "MSAA", etc. All of these methods are approximations, but they're very fast. FXAA and TAA are basically just really fancy blurs, and MSAA can only smooth polygon edges; pixelated textures are totally missed out on, which is most of what Minecraft is. Super-sampling is the most pure, accurate, and expensive form of antialiasing. The entire scene is rendered at a higher resolution, and then downscaled for presentation. It's also the easiest to implement. !(https://blob.jortage.com/blobs/b/d44/bd446ebab0263ff81deb3f127d00c7a818e4c91bc84a06f7a3dd1d0ced7eb1f0f270748ef68752d285fe31fe91a9ea603fbe8092cf48a7b7c7cedea117928566) For example, if you're playing in a 1280×720 window, then QDAA will render the game at *2560×1440* instead, and then resize it to 1280×720 before it's drawn to the screen. This mod reuses functionality in Minecraft that handles macOS Retina displays, so it should be quite compatible, except with other mods that modify how the framebuffer is drawn to the screen. It also technically optimizes the final render step, replacing a normal quad render with a blit. Notably, due to how this works, **QDAA can even antialias GUIs**, improving readability of rotated text and smoothing the edges of 3D item models. Shaders only work on the world. ## Versions 2.0 is an xplat redesign of QDAA based on the old "Simple" version, which works on 1.21.1+. Historically, QDAA is available in both "Simple" and "Configurable" versions, which are v1.1 and v1.2 due to having no foresight. ### Simple Really basic implementation of just the AA. ~~Works on any version with Blaze3D, pinky promise. Will likely never need updating. Remind me if I forget to tag new versions.~~ Mojang refactored how their framebuffer code works, so it broke. Yay. 2.0 exists to fix this. **Note**: 1.16 and earlier only (https://blob.jortage.com/blobs/7/3d4/73d4a6b5e2bb3172856992ccddbdf281b17105075ad07be9f4919d75dea913d9a4f7249196e40ef061a653354dd617942f9897668e07dad5bd497f65c3bcceb9) work. Only 1.18 and higher is supported. ### Configurable More "full-fledged" mod with a config screen and runtime toggling. Potentially useful to ship in modpacks off-by-default. Highly version-dependent due to usage of GUIs. Likely won't receive updates, I regret it.
