mach-examples VS angle

Zig fits pretty naturally here too. We've got ~19 WebGPU examples[1] which use Dawn natively (no browser support yet), and we build it using Zig's build system so it 'just works' out of the box with zero fuss as long as you grab a recent Zig version[2]. No messing with cmake/ninja/depot_tools/etc.

WASM support in Zig, Rust, and C++ is also not equal. C++ prefers Emscripten which reimplements parts of popular libraries like SDL, for me personally that feels a bit weird as I don't want my compiler implementing my libraries / changing how they behave. Rust I believe generally avoids emscripten(?), but Zig for sure lets me target WASM natively and compile C/C++ code to it using the LLVM backend and soon the custom Zig compiler backend.

Mach core (pretty much ready for use today): a modern alternative to e.g. SDL+OpenGL which gives you just a Window+Input+GPU. We have ~16 examples including texturing, PBR, deferred rendering, etc.

It's using MoltenVK on Mac for Vulkan compatibility, and ANGLE for OpenGL compatibility on Windows and Linux. Makes you wonder what it's actually doing itself.

Can't they use https://github.com/google/angle?

BTW. For the last 15 years, all web browsers on Windows do WebGL on top of DirectX (using the Angle library https://github.com/google/angle).

You can still use OpenGL. Just not the vendor provided drivers. They are indeed horrible. There are libraries like:

* ANGLE ( https://github.com/google/angle ) - An OpenGL ES implementation with Direct3D 9, Direct3D 11, Desktop GL, GL ES, Vulkan and Metal backends. This is what we used to use for shipping our Qt 3D application, that used a bunch of OpenGL Shaders. We used to get bug reports about various shaders not working properly on various hardware. After switching to this, all those bug reports vanished.

* Zinc ( https://www.supergoodcode.com/do-not/ ) - A more recent, OpenGL implementation on top of Vulkan. I haven't used this one yet. But they are making a lot of progress and it is almost as performant as vendor provided OpenGL Drivers these days. So if I ever have to ship a desktop app, needing opengl, I'd strongly consider using this.

Another option if perf isn't a big concern is to try using Google's angle OpenGL ES 3.0 implementation, there's backends for it to be supported on Vulkan, Direct3D 11, and (work in progress) Metal. Disclosure, haven't tried it myself, just looking at their feature descriptions: https://github.com/google/angle

I don't believe Chrome uses OpenGL directly- any OpenGL usage it does have (e.g. for WebGL) is actually going through ANGLE which translates it all to D3D on Windows.

RTFM, have you read their instruction
