This is the replay tool for FNA3D trace files.
About
-----
Traces are made with a custom FNA3D binary that writes the entire call stream,
including texture and buffer data, and contains no backend information of any
kind. This ensures that traces made from any platform can be played back on
every other platform, and can be rendered with any backend that FNA3D provides.
How to Use
----------
To enable tracing, set -DTRACING_SUPPORT=ON when configuring via CMake. If you
use one of the premade projects, simply add FNA3D_TRACING to the defines.
Place the FNA3D library where appropriate, then run your application for as long
as is appropriate. Note that you will want both a lot of disk space as well as
good disk performance, as these files get large VERY quickly! Once the file is
made, you can play it back with `fna3d_replay`.
Found an issue?
---------------
Like with FNA3D, tracing issues should be reported via GitHub, but if you want
to diagnose crashes yourself, the easiest way is to simply printf the `mark`
value right before the big giant switch statement, then you can work your way
from there once you know which API call caused the problem.
