GitHub - facebook/igl: 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).
Intermediate Graphics Library (IGL) is a cross-platform library that commands the GPU. It encapsulates common GPU functionality with a low-level cross-platform interface. IGL is designed to support multiple backends implemented on top of various graphics APIs (e.g. OpenGL, Metal and Vulkan) with a common interface.
There are a lot of good options for abstracting GPU API's; each making different trade-offs. We designed IGL around the following priorities:
Low-level, forward-looking API. IGL embraces modern abstractions (command buffers, state containers, bindless, etc) and is designed to give more control than OpenGL's state machine API. As a result, IGL can have leaner backends for modern API's (e.g. Metal, Vulkan).
Minimal overhead for C++. IGL supports new or existing native rendering code without overhead of language interop or the need for other language runtimes.
Reach + scale in production. IGL has been globally battle-tested for broad device reliability (especially the long-tail of Android devices as well as Quest 2/3/Pro compatibility for OpenGL/Vulkan) and performance-tuned on our apps.
