| TOTAL FOR OCTOBER (1) | 13 hours |
TOTAL FOR PERIOD 1 : 128 hours [PAID]
Period 2
| Date | Time | Tasks |
|---|---|---|
| 2008-oct-21 | 3 hours | Configure and generate Doxygen for Monographic. Continue the camera stuff and some code re-arangement. |
| 2008-nov-24 | 2 hours | Getting back to the code, end of refactoring. |
| 2008-dec-01 | 2 hours | Commit to mercurial, try to fix the hack who force the 406 to be loaded (can't be fixed until we're more advanced, since it require the whole drivers XML files to be parsed).
Render the user-requested cameras to files (for easy sharing point of views requested by the vision engine). |
| 2008-dec-02 | 4 hours | Solved a Monodevelop bug (I wasn't able to compile anymore...). Work on "TorcsDotNet", the Track is loaded using the C++ plugin from a C# application. |
| 2008-dec-04 | 4 hours | Work on "TorcsDotNet", the Ogre graphic module is initialized and displays the Track, start investigating the creation of a tSituation (found raceman.h / raceinit.cpp). |
| 2008-dec-08 | 3 hours | Work on "TorcsDotNet", wrapping the raceengine for creation of drivers and situation. |
| 2008-dec-09 | 2 hours | Wanted to know what robots exactly need to drive (C version and SharpyCS one). SharpyCS uses nothing different than C robots (ie torcs C interface).
Decision is to wrap the C robots so we'll have all drivers available. |
| 2008-dec-10 | 2 hours | Work to wrap raceinit's InitCars, which initialize olethros. It bugs... Trying to figure out why. |
| 2008-dec-13 | 2 hours | Compile Olethros within Monodevelop project. Wrapped GfParm to load torcs' parameters files from C# RaceEngine. |
| 2008-dec-15 | 3 hours | Olethros loaded and initialized. Now we go to another big part : initialize a race. |
| 2008-dec-16 | 4 hours | Better wrapping of a few core classes. Start loading the car structure (tCarElt).
Study of Torcs source code to understand all the informations available/needed for cars simulation and driving. |
| 2008-dec-17 | 3 hours | Including SimuV2 and SOLID-2.0 into TorcsDotNet. Fighting against a Monodevelop bug...
Trying to figure out how I can monitor my activity inside Monodevelop (for precise time management). |
| 2008-dec-18 | 4 hours | Starting to wrap in C# SimuV2
Fixed all C# <-> C++ structure alignment bugs using __attribute__((__packed__)) on C++ side and [StructLayout (LayoutKind.Sequential, Pack=1)] on C# side... It crashed.. Hardcore debugging.. Finally discovered a bug in Mono! Under some circonstances C# Packed structures are not duplicated correctly (miss a few bytes at the end). I need to reproduce it on a simple example to submit a bug report. Removed the dependency over PLIB by including in the project the very few functions used by Torcs core. |
| 2008-dec-19 | 1 hour | Reproduce the mono bug on a small example, filling bug report: https://bugzilla.novell.com/show_bug.cgi?id=460608 |
| 2008-dec-20 | 4 hours | My bug is said to be solved in mono's SVN, so I got it and am compiling mcs from source to check this.
Writing unit tests to make sure all C# <-> C++ data structure conversions are bugless (since those bugs are *very* hard to track, as I made the experience). Adding a check for the 'Pack=1' bug: which warns if it occurs. Latest version of mono do not have this bug so I'm now gonna change my all source code... just presume users have a non-buggy compiler. |
| 2008-dec-23 | 2 hours | Install/compile Torcs, Mono, Monodevelop and OgreDotNet on my eeePC. Solve Torcs' GCC 4.3 compile errors. |
| 2008-jan-8 | 3 hours | Work on C# Simu wrapper. Initialize the CarElt array of tSituation. Thinking about C#/C++ data synchronization for dynamic structures. |
| 2008-jan-12 | 3 hours | Initialize TCarElt fields (by porting the raceinit.cpp code to C#). Facing a strange exception thrown by the mono runtime (the JIT precisely). I suspect it doesn't like my unmanaged memory allocations. |
| 2008-jan-13 | 2 hours | Investigate proper ways to implement C#/C++ interoperability. Reading MSDN and papers. |
| 2008-jan-14 | 3 hours | Investigate SWIG. Torcs C interface described. SWIG generated code integrated into the project. Making previous version (TorcsItf) obsolete. |
| 2008-jan-15 | 3 hours | Make nice SWIG wrapper for Torcs interface, clean existing code accordingly. |
| 2008-jan-16 | 2 hours | Improve Robot and Car wrapper, learn more deeply SWIG in order to extend its generated interfaces.. |
| 2008-jan-17 | 3 hours | Improve Track, ModInfo and Situation. Create an object oriented version of GfParm using SWIG. Rename variables so they starts with uppercase in C#. |
| 2008-jan-20 | 4 hours | Fix GfParm wrapper, learned own to customize SWIG generated code. |
| 2008-jan-21 | 3 hours | Finish to fix all compilation bugs related to the changes in the interface, so we're now back to previous state but with a much cleaner code.
Getting back to initialization of car structures (tCarElt) -- which doesn't segfault anymore (yeepee!). |
| 2008-jan-22 | 4 hours | Apply some polish to Car and Track interfaces. Write the C# version of InitStartingLine(). Move some code from Main() to the RaceManager. |
| 2008-jan-23 | 4 hours | End of the initialization stuffs. The simulation run, car positions are updated... but get random values.
Some important structure members might be uninitialized. Need to do some debugging. |
| 2008-jan-24 | 7 hours | Completed SwigTorcs. Learned how to wrap array structure members to C# array. Wrote lots of Swig Macros.
Been through all torcs interface headers to rename all variables and wrap all arrays cleanly. Splitted Swig wrapper into several files: simulator/interface/*.i Wrote a script which compiles the code, so I do not always need to launch Monodevelop (compile.sh at torcsdotnet's root). |
| 2008-jan-26 | 2 hours | C# simulation manager reached a working state. Plugins are initialized correctly, the car runs smoothly around the track. |
| 2008-jan-27 | 4 hours | Registered the project on sharesource.org. Preparing a package which compiles with autotools, check for dependencies and everything (in progress). |
| 2008-jan-28 | 5 hours | Projet accepted by sharesource.org. Packaging source with autotools complete (I need to package data now).
Removed some hard coded path in the graphic engine code by reading appropriate variables. Improved OgreDotNet renderer's management of resources (textures and stuffs). |
| 2008-feb-01 | 4 hours | Commited project to ShareSource. Adding little document on project wiki for installation. Fixing installation bugs.
Cleaning the data folder (3D models are now stored in zip files together with their textures and shaders). Installing user-mode-linux in order to test compilation/installation. On various systems and from an empty system, to write a clean "how-to-install" documentation. |
| 2008-feb-02 | 7 hours | Finishing to clean every hacks. Now ./configure && make && make install do everything for you!
Updating "how-to-install". Preparing the interface for C# robots. Creating a stupid SharpyRobot.cs which drives straight to the wall as an example. If WD like to ports Sharpy to OpenRacing, I'll start writing minimal GUIs for selecting Robots and Tracks, or start working on user inputs. |
| 2008-feb-03 | 6 hours | Exploring GUI libraries. Many things available for Ogre but just a few have C# interface, and most them are dead projects...
I got MyGUI working, the example is nice looking and the API simple so I wrote minimalist C# wrapper for basic functions. I'm now trying to have something working with this inside OpenRacing. |
| 2008-feb-04 | 6 hours | I improve MyGUI# (I found my C# DLL wasn't working), now it's clean! Continue with the wrapper (as well as learning how MyGUI works).
Created an example OgreDotNet + MyGUI# application for demo and experimentation purposes. OpenRacing now initialise MyGUI and add widgets on screen (just useless buttons, images and windows for now). Some conception for integrating GUIs in OpenRacing had to be made: the graphic plugin is now in charge of rendering GUIs. (because as we seen in Torcs, rendering of GUIs and 3D stuffs inside the same window with two different engines is not a good idea) |
| 2008-feb-06 | 3 hours | GraphicModule can now be initialized without being given Track and Cars, so we can load only the GUI. Starting input support using OIS through SWIG's framework. |
| 2008-feb-08 | 3 hours | Initial input support is working, wrapper dispatches EXIT events. Contacting MyGUI's guy to see if they are interested by a SWIG wrapper.
(problem is that they've already written a Managed C++ wrapper but Managed C++ isn't supported by Mono). |
| 2008-feb-10 | 3 hours | Minimal GUI is now working (with mouse and keyboard, using SWIG directors to specify C# callbacks to a C++ API).
Analysing torcs-ng mailing list. Working on the email for Torcs-NG guys. |
TOTAL FOR PERIOD 2 : 128 hours [PAID]

Compile and install torcs-ng. Studying trackgen-ng. Tracking MyGUI's initialization bug. I give up until the official wrapper is out. Ogre display suddenly became buggy too. It's probably due to the fact I installed ogre 1.4.5 (from ubuntu source package) to replace 1.4.9. Updated MyGUI's SVN (to see if there is anything new for C#). It didn't compile anymore... Fixing a few stuffs. Add few blueprints to launchpad.. |
| 2008-feb-20 | 3 hours | (27h) Start refactoring Trackgen, understanding current design and thinking of next-gen one. Code pushed to a separated bzr repository:
https://code.launchpad.net/~jeko-ios-software/openracing/trackgen2 |

| 2008-feb-25 | 3 hours | (33h) Get ogre 1.4.9 back. Graphics are back, so it's true the graphics problems came from this. Commit and push to bzr. Mails & chat with Kilo and Keith. |
| 2008-feb-28 | 5 hours | (38h) Chat, mails and wiki about UTI's design.
Reverted GUI to a forked version of MyGUI containing SWIG C# wrapper. Created a bazaar repository. Solved a bug for car orientation (discovered this one thanks to the car chasing camera). |
| 2008-mar-10 | 5 hours | (43h) Help Imre with the weird bug. Solved MyGUI's crash. Initial handling of OIS from OpenRacing, creation of the Human robot module. |
| 2008-mar-11 | 4 hours | (47h) Working keyboard driving with OIS (yeah it's cool!). Implementing Joystick support on OIS side, but it's not handled by human robot yet.
And it's untested since I don't have a joystick (I'm going buy one right now). |
| 2008-mar-12 | 4 hours | (51h) Implementing joystick integration... But it doesn't work. Impossible to get to joystick recognized and work with OIS.
OIS have to be launched as root. Then joystick is recognized, but not working... Finally upgrading to OIS version 1.2. |
| 2008-mar-13 | 4 hours | (55h) Finish joystick support. Some planning with Keith and Imre. Helping Imre with debugging. |
| 2008-mar-14 | 3 hours | (58h) HUD for RPM and speed. |

Help Imre with debugging.. Study Torcs' OpenAL code (O.R misses sound, and I thing I can SWIG-wrap this code from Torcs quite easily). Initial ODE integration (Tao's libraries are a joy to use!), learn how ODE works. |
| 2008-mar-17 | 7 hours | (70h) Work with Imre on ODE integration. Free-ride OpenRacing almost working. |
| 2008-mar-18 | 3 hours | (73h) Debugging free-ride on simuv2's side with a custom raycaster, I was able to do the first free ride (ended by a crash). |
| 2008-mar-19 | 2 hours | (75h) Give a hand to Keith for OR installation. Explore ODE bug. |
| 2008-mar-20 | 2 hours | (77h) Found ODE bug: 64bits machins requires to upgrade to ODE 0.11. Fixing Tao accordingly. |
| 2008-mar-23 | 2 hours | (79h) Adding an option to turn shadows off. Add an XML configuration file. |
| 2008-mar-24 | 3 hours | (82h) Adds a configuration GUI, store conf to XML, allows dynamic change of rendering quality, cleanup GUI code. |
| 2008-apr-03 | 4 hours | (86h) Installing Jaunty, installing OpenRacing on it, making the initial monodevelop 2 project. |
TOTAL FOR PERIOD 3 : 86 hours [PAID]
Period 4
| Date | Time | Tasks |
|---|---|---|
| 2008-apr-22 | 3 hours | (3h) Reading emails sent during last weeks. Getting monodevelop 2 knows about assembly references (for autocompletion and debugging). |
| 2008-apr-23 | 2 hours | (5h) Got better understanding of Makefile integration, had to recreate a Monodevelop project from scratch.
"Gac" references now can be found and are synchronized with makefiles, but the project doesn't compile or execute. |
