gfx-rs

Documentation is hosted on rust-ci.

gfx-rs is a high-performance, bindless graphics API for the Rust programming language. It aims to be the default API for Rust graphics: for one-off applications, or higher level libraries or engines.

Why gfx-rs?

• Graphics APIs are mostly designed with C and C++ in mind, and hence are dangerous and error prone, with little static safety guarantees.
• Providing type safe wrappers around platform-specific APIs is feasible, but only pushes the problem of platform independence to a higher level of abstraction, often to the game or rendering engine.
• Modern graphics APIs, whilst providing a great degree of flexibility and a high level of performance, often have a much higher barrier to entry than traditional fixed-function APIs.
• Graphics APIs like OpenGL still require the developer to 'bind' and 'unbind' objects in order to perform operations on them. This results in a large amount of boiler plate code, and brings with it the usual problems associated with global state.

Goals

gfx-rs aims to be:

• type-safe and memory-safe
• compatible with Rust's concurrency model
• highly performant with minimal latency
• an abstraction over multiple graphics APIs: OpenGL, Direct3D, Mantle, etc.
• orthogonal to context backends: GLFW, SDL2, gl-init-rs, etc.

Non-goals

gfx-rs is not:

• a rendering engine
• a game engine
• bound to a specific maths library

gfx-rs will not handle:

• window and input management
• mathematics and transformations
• lighting and shadows
• visibility determination
• draw call reordering
• de-serializing of scene data formats
• abstractions for platform-specific shaders
• material abstractions

Getting started

Add the following to your Cargo.toml:

~~~toml [dependencies.gfx] git = "http://github.com/gfx-rs/gfx-rs" ~~~

See the triangle example for a typical context initialization with glutin, or cube example for glfw.

Note

gfx-rs is still in the early stages of development. Help is most appreciated.
