Boo

Boo is a cross-platform windowing and event manager similar to SDL and SFML, with additional 3D rendering functionality.

The exclusive focus of Boo is 2D/3D rendering using polygon-rasterization APIs like OpenGL or Direct3D. It exposes a unified command-queue API for calling the underlying graphics API.

The only per-platform responsibility of the client code is providing the shaders' source. Drawing, resource-management and state-switching are performed using the unified API; these may be written once for all platforms.

Client code is entered via the appMain method supplied in a callback object. This code executes on a dedicated thread with graphics command context available. The API may be used to synchronize loops on the client thread with the display refresh-rate.
