How could this debug build run any slower? How about strace -k!
Maybe<Maybe<uint32_t>> surely means I messed up somewhere along the line.
Always be reading specs: Not only is GL matrix data column-major, but the types are COLSxROWS, not ROWSxCOLS.
Once more, a malformed glViewport claims an hour of debugging.
there's an interactive demo by @playcanvas to check out once you update, too: mzl.la/2jaAGVC
🎮 @ladybenko and @jedagil invite you to flex those GL-shader-muscles — Firefox 51 ships today, with #WebGL2 support! hacks.mozilla.org/2017/01/webgl-…
At least we warn about this in WebGL!
Another day, another 30m wasted because GL textures default to requiring a mip chain, silently drawing black with only one level specified.

@kamidphish @ID_AA_Carmack We did it in B2G sorta, but that was by wrapping gralloc buffers in eglimages. Not FDs from images.
You wanted it, you got it. Behold: resizable, smaller tabs!
@kamidphish @ID_AA_Carmack KHR_debug makes it possible outside WebGL, but it's up to drivers. PBO errors on nVidia are useless.
It's here! Runtime Generated Lightmaps for #WebGL blog.playcanvas.com/runtime-lightm…
Surprise! Serious Sam source code released. You can grab the files here: github.com/Croteam-offici…
@kamidphish Pretty much! Some devs did some great hacks to eak out more precision. It gets real weird though.
Vulkan appears to handle depth [0,1] instead of GLSL's unfortunate-for-precision [-1,1]!
