point-frag is a small code base to play with multi-threading and distributed tasking systems for a game engine. The overall idea is to remove the notion of "main" thread or "rendering" thread and to only have worker threads. The game itself is just a infinite task that respawns itself all the time from frame to frame.
The code base uses CMake to build. CMake can be downloaded at www.cmake.org The classical CMake profiles are supported (Debug, Release, RelWithDebInfo, MinSizeRel).
- On Windows, use basically the user interface to generate the VS solutions.
- On Linux, you can use ccmake to get the similar user interface.
- The code may work on MacOS but I did not have a Mac to test it.
The code was tested and compiled on:
- Linux 32/64 bits. You need a relatively new compiler since the code use unordered_map. Note that the code can compile with both GCC and clang. ICC is not supported due to some problems related to the use of some c++11 features
- Windows 32 bits with VS2008 (but memory debugger which uses unordered_map is not supported)
- Windows 32/64 bits with VS2010
Beyond the build mode, you may choose to use a memory debugger (it will slow down the system considerably since it locks malloc/free) by setting the variable PF_DEBUG_MEMORY with CMake
Also, note that parts of the code (related to mutexes/conditions/multi-platform abstraction) were directly taken from Intel Embree project: http://software.intel.com/en-us/articles/embree-photo-realistic-ray-tracing-kernels/
Just run game (or game.exe). The code has been tested on recent AMD and NVidia cards
