Blade Graphics

Blade-graphics is a lean and mean GPU abstraction aimed at ergonomics and fun. See motivation, FAQ, and performance for details.

Platforms

The backend is selected automatically based on the host platform:

Vulkan on desktop Linux, Windows, and Android
Metal on desktop macOS, and iOS
OpenGL ES3 on the Web

Feature	Vulkan	Metal	GLES
compute	:white_check_mark:	:white_check_mark:
ray tracing	:white_check_mark:

OpenGL ES

GLES is also supported at a basic level. It's enabled for wasm32-unknown-unknown target, and can also be force-enabled on native:

RUSTFLAGS="--cfg gles" CARGO_TARGET_DIR=./target-gl cargo test

This path can be activated on all platforms via Angle library. For example, on macOS it's sufficient to place libEGL.dylib and libGLESv2.dylib in the working directory.

WebGL2

Following command will start a web server offering the bunnymark example:

cargo run-wasm --example bunnymark

Vulkan Portability

First, ensure to load the environment from the Vulkan SDK:

cd /opt/VulkanSDK && source setup-env.sh

Vulkan backend can be forced on using "vulkan" config flag. Example invocation that produces a vulkan (portability) build into another target folder:
