API Reference
=============
.. note::
If you're just getting started with bgfx, you might get more out of these simple walkthroughs for how to use bgfx's API:
- `Hello, bgfx! <https://dev.to/pperon/hello-bgfx-4dka>`_
- `bgfx-minimal-example <https://github.com/jpcy/bgfx-minimal-example#bgfx-minimal-example>`_
- `Using the bgfx library with C++ on Ubuntu <https://www.sandeepnambiar.com/getting-started-with-bgfx/>`_

Views
-----
Views are the primary sorting mechanism in bgfx.
They represent buckets of draw and compute calls, or what are often known as 'passes'.
When compute calls and draw calls occupy the same bucket, the compute calls will be sorted to execute first.
Compute calls are always executed in order of submission, while draw calls are sorted by internal state if
the View is not in sequential mode.
In most cases where the z-buffer is used, this change in order does not affect the desired output.
When draw call order needs to be preserved (e.g. when rendering GUIs), Views can be set to use sequential mode with `bgfx::setViewMode`.
Sequential order is less efficient, because it doesn't allow state change optimization, and should be avoided when possible.
By default, Views are sorted by their View ID, in ascending order.
For dynamic renderers where the right order might not be known until the last moment,
View IDs can be changed to use arbitrary ordering with `bgfx::setViewOrder`.
A View's state is preserved between frames.
