Alphabetizes includes and resolves quite a few instances of indirect inclusions, making the requirements of several interfaces explicit. This also trims out includes that aren't actually necessary (likely due to changes in the API over time).
Boo
Boo is a cross-platform windowing and event manager similar to SDL or SFML, with additional 3D rendering functionality.
The primary 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.
Boo also features a unified audio API for mixing voices and performing variable sample-rate-conversion. All audio computation occurs on the CPU, synchronously 'pumped' by the client each frame-iteration.
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.
Supported Graphics Backends
- OpenGL 3.3+
- Direct3D 11
- Metal 1.1 (OS X 10.11 only for now, iOS coming soon)
- Vulkan
Supported Audio Backends
- [Windows] WASAPI
- [OS X] Audio Queue Services
- [Linux] ALSA
Pro Logic II Encoding Support
The Boo audio engine supports real-time Pro Logic II surround matrixing for 5.1 client mixes.
Call IAudioVoiceEngine::enableLtRt(true); to enable this functionality.
Note: Before building Boo, the Intel Integrated Performance Primitives must be installed for full surround-sound encoding capabilities. Without this library, only the left, right, and center channels will be encoded. The surround channels are phase-shifted 90-degrees using the Hilbert functions in the library.
