Thallium Graphics Library

The Thallium Project is a library for C/C++ applications that will provide the ability to write cross-renderer applications with the same interface. Cross-platform APIs (i.e. Vulkan and OpenGL) will be prioritised, but I plan to also implement dumber APIs such as Metal, DX11, and DX12 in the far future.

As a side-note, I track TO-DO items on Trello. GitHub issues on this repository are also used to track bugs or requests.

Documentation

For the Thallium API documentation, see the GitHub Pages instance at https://kosude.github.io/thallium/.

Local HTML documentation can be generated at compilation with the -DTHALLIUM_BUILD_DOCS=ON flag, as above. This is not default behaviour and is not recommended, as it can lengthen build time, and requires Doxygen to be installed as well as several Python modules (listed in the docs/requirements.txt file for pip).

Building

CMake is used to generate build files. Ideally, you should build in a Linux environment - do note however that MinGW32 and subsystems like Cygwin and MSYS2 have not yet been tested.

General options

The following is a table of available CMake configuration options for Thallium. Note that this list may be missing some, so check the appropriate CMakeLists.txt file to make sure.

Option name	Description	Default
BUILD_SHARED_LIBS	Build shared libraries	ON
THALLIUM_BUILD_LIB	Build the Thallium library	ON
THALLIUM_BUILD_TESTS	Build Thallium tests	OFF
THALLIUM_BUILD_EXAMPLES	Build Thallium example projects	OFF
THALLIUM_BUILD_DOCS	Build HTML documentation	OFF

API modules

Thallium source compilation is split into modules, based on the graphics APIs you need support for. Each module can be manually enabled or disabled with CMake flags, just like above. These flags are named THALLIUM_BUILD_MODULE_<API>. For example, the Vulkan module can be compiled using the -DTHALLIUM_BUILD_MODULE_VULKAN=ON build flag (this requires the Vulkan SDK to be installed).

WSI flags

Window system integration (WSI) is available depending on the target platform:

• On Apple systems, THALLIUM_WSI_COCOA is available and enabled by default.
• On other *nix systems, THALLIUM_WSI_XCB and THALLIUM_WSI_XLIB are both available and enabled by default. Wayland is not yet supported.

Information for contributing

Document all new public functions or types with Doxygen-style formatting. Also see the Breathe documentation to find out how to include your code's documentation in the HTML output.
