Meta Releases Intermediate Graphics Library

• igl

  13 2,740 9.9 C++

  Intermediate Graphics Library (IGL) is a cross-platform library that commands the GPU. It provides a single low-level cross-platform interface on top of various graphics APIs (e.g. OpenGL, Metal and Vulkan).

  

For an intermediate library, it doesn't seem to be actually very much backend-independent. At least the desktop sample [1] has a disappointing amount of code paths with parallel implementations for OpenGL and Vulkan, switched at compile time using "#if USE_OPENGL_BACKEND".

I guess this means that this sample will use OpenGL rather than Metal on macOS? They claim there's a Metal backend, but how would one enable that for the "Tiny" sample? By manually adding a third parallel implementation with "#elif USE_METAL_BACKEND" everywhere?

• sokol

  38 6,388 9.7 C

  minimal cross-platform standalone C headers

If you're looking for something like this, Sokol is a much simpler alternative:

https://github.com/floooh/sokol

It doesn't support vulkan though, but if that's important to you you're probably much better off just using vulkan directly since it's supported on all the major platforms.

• wgpu

  197 11,247 9.9 Rust

  A cross-platform, safe, pure-Rust graphics API.

  

• rend3

  14 1,038 7.9 Rust

  MAINTENCE MODE ---- Easy to use, customizable, efficient 3D renderer library built on wgpu.

  

The WGPU people are still working through lock conflicts in that area. The idea with Vulkan land is that you should be able to load content while rendering is in progress. For that to be useful, all the layers above Vulkan also have to have their locking problems hammered out. Most open source game engines don't do that yet. Unreal Engine and Unity do, which is why you pay for them for your AAA title.

• sokol-tools

  5 203 7.3 C++

  Command line tools for use with sokol headers

Sokol also provides a solution for shader cross-compilation (https://github.com/floooh/sokol-tools/blob/master/docs/sokol...), so you only need to write your shaders once no matter if you're targeting OpenGL, Metal, or DirectX.

There are other tools you could use out there with IGL, but Sokol's solution streamlines the whole process.

• SFML-IGL

  1 3 3.6 C++

  Rendering example with Meta's Intermediate Graphics Library and SFML

It integrates quite easily with SFML. I took the Tiny example, removed the OpenGL branching and replaced the GLFW code with SFML.

• MoltenVK

  103 4,598 9.0 Objective-C++

  MoltenVK is a Vulkan Portability implementation. It layers a subset of the high-performance, industry-standard Vulkan graphics and compute API over Apple's Metal graphics framework, enabling Vulkan applications to run on macOS, iOS and tvOS.

  

Khronos maintains MoltenVk though, which is "official" as it gets: https://github.com/KhronosGroup/MoltenVK

...technically, Vulkan on Windows is also only supported via 3rd-parties (the GPU vendors), Microsoft doesn't support Vulkan either ;)
