Debugging and Profiling
-----------------------
RenderDoc
~~~~~~~~~
Loading of RenderDoc is integrated in bgfx when using DX11 or OpenGL
renderer. You can drop in ``renderdoc.dll`` from RenderDoc distribution
into working directory, and it will be automatically loaded during bgfx
initialization. This allows frame capture at any time by pressing
**F11**.
Download: `RenderDoc <https://renderdoc.org/builds>`__
RenderDoc `How do I ...? <https://renderdoc.org/docs/how/index.html>`__ documentation.
`Shader debugging <https://software.intel.com/en-us/articles/shader-debugging-for-bgfx-rendering-engine>`__
with RenderDoc and MSVC.
SDL, GLFW, etc.
---------------
It is possible to use bgfx with SDL, GLFW and similar cross platform
windowing libraries. The main requirement is that windowing library
provides access to native window handle that's used to create Direct3D
device or OpenGL context.
For more info see: :doc:`bgfx`.
.. note:: You can use ``--with-sdl`` when running GENie to enable SDL2 integration with examples:
``genie --with-sdl vs2012``
.. note:: ``--with-glfw`` is also available, but it's just simple stub to be used to test GLFW
integration API.
.. note:: Special care is necessary to make custom windowing to work with multithreaded renderer.
Each platform has rules about where renderer can be and how multithreading interacts
with context/device. To disable multithreaded render use ``BGFX_CONFIG_MULTITHREADED=0``
preprocessor define.
Getting Involved
----------------
Everyone is welcome to contribute to bgfx by submitting bug reports, testing on different
platforms, writing examples (see `ideas <https://github.com/bkaradzic/bgfx/issues?q=is%3Aissue+is%3Aopen+label%3A%22help+needed%22>`__),
improving documentation, profiling and optimizing, etc.
.. note:: **When contributing to the bgfx project you must agree to the BSD 2-clause
licensing terms.**
