= About =

This includes a set of tools for:
- trace OpenGL, D3D8, and D3D9 APIs calls to a file;
- retrace OpenGL calls from a file;
- visualize trace files, and inspect state.


= Status =

* It has not been tested with many applications. Bugs in less used features may
  cause application crashes.
* Direct3D 8 support is currently broken.
* No Direct3D retrace support


= Building from source =

Requirements common for all platforms:
* Python (requires version 2.6)
* CMake (tested with version 2.8)

Requirements to build the GUI (optional):
* Qt (tested with version 4.7)
* QJSON (tested with version 0.7.1)


== Linux ==

Build as:

 cmake -H. -Bbuild
 make -C build


== Windows ==

Requirements:

* Microsoft Visual Studio (tested with 2008 version) or MinGW (tested with gcc version 4.4)

* Microsoft DirectX SDK (tested with August 2007 release)

To build with Visual Studio invoke CMake as:

 cmake -G "Visual Studio 9 2008" -H. -Bbuild
 cmake --build build --config MinSizeRel
 
It's also possible to build on Linux with MinGW cross compilers.  See
http://www.cmake.org/Wiki/CmakeMingw for detailed instructions.


= Usage =


== Linux ==

* Run the application you want to trace as

 LD_PRELOAD=/path/to/glxtrace.so /path/to/application

* View the trace with

 /path/to/dump application.trace

* Replay the trace with

 /path/to/glretrace application.trace


== Windows ==

* Copy opengl32.dll, d3d8.dll, or d3d9.dll from build/wrappers directory to the
  directory with the application you want to trace.

* Run the application.

* View the trace with

 /path/to/dump application.trace

* Replay the trace with

 /path/to/glretrace application.trace
