== Achieving OTI ==
== Achieving UTI ==


This is little thinking about torcs/openracing interdependencies..
[[Achieving UTI]]
The goal of this thinking is to simplify the code, by getting rid of as much C++ as possible, especially if it is useless.
 
=== Facts ===
 
* The only ''hard'' dependency that OR does have on Torcs' C++ code is simuv2 ('''simuv2 works with tTrack, tCarElt and tSituation''').
** This in turn create a dependency over '''torcs track plugin''', which is required '''to load a tTrack''' properly.
* The '''robot interface depends on tCarElt''' for compatibility with Torcs AI, this '''can be dropped''' for now (we have C# robots), and we can find a cleaner solution later on.
** The robot itself is responsible for loading the car informations (via an XML GfParm file).
* '''RaceManager inits tCarElt''' using informations given by the Robot's XML, then associate the car with the robot (see '''Q1''').
* '''RaceManager inits tSituation'''.
 
=== Quick remainder ===
 
* tTrack is the logical track as stored and manipulated in C++ by Torcs (i.e. track trajectory and width basically as a list of segments)
* tCarElt is the information about a car. positions of elements, wheels, fuel, driving commands, etc... (hundreds of fields in the structs)
* tSituation describe the situation of a race. List of cars, the track, some global infos.
 
=== Questions ===
 
'''Q1''': Should the robot decide the features of his car?
 
It seems more natural to me to build a car then put a driver into the car (instead of the opposite). Maybe some AI are very specific to drive a particular car, let's forget about that first: we simplify!
 
=== Killing C++ Howto ===
 
* Get rid of all C++ code not needed by simuv2.
** 1. disable legacy c++ robots
** 2. C# code that needs to access/modify t* struct should do it through an interface (will will very probably serve as a base for OTI).
** 3. Comment out and remove as much C++ code as possible.
 
* Simplify simuv2
** simuv2 no longer manages collisions, we should be able to get rid of Solid.
 
==== Disabling C++ robots ====
 
This should allow to disable learning, robottools.
 
==== Separate C# code from current data structures ====
 
Will make changes to those easier.
 
=== Numbers ===
 
The indicator is the number of lines of C++ compiled in libsimulator.so. Goal is 0 (one day maybe).
 
* 22/06, 5:00pm. '''39223''' lines
* 23/06, 3:00pm. '''32984''' lines (removed c++ drivers)
* 23/06, 3:30pm. '''31697''' lines (removed learning)
* 23/06, 5:00pm. '''31565''' lines (tried to remove robottools... but track have a dependency over it. simplifying what can be)
* 24/06, 5:00pm. '''30817''' lines (removed gnulinux)
* 24/06, 6:00pm. '''30116''' lines (removed simuv2 collision handling code, '''removed simuv2's dependency over the track format''')

Tasks & Plans

Achieving UTI

Achieving UTI

Tasks

Ogre renderer

  • Automatic car 3D model conversion. (can be called "automatic AC3D to Ogre conversion").
  • Automatic track 3D model conversion from Torcs-NG's data (starting from trackgen). Should warn about unsupported geometry and such.

Driver

  • Load sharpy's driver, make it run a car

User interface

  • Make a GUI designed for our needs (load a track, evaluate drivers, run simulation in background, ...) : WIP
  • Work on the installation process

Screenshots

Bellow, you'll find some screenshots showing work in progress of Ogre renderer and GUIs.

  • OpenRacing gallery
  • 2008-sep-08, high-quality skybox, back to stencil shadows

Old tasks

Ogre renderer

  • Make a camera follows a car (from behind) : DONE.

Core engine

  • Load a complete track using C++ plugin : DONE.
  • Initialize OgreDotNet graphic plugins to display the track : DONE.
  • Load cars / physics engine : DONE.
  • Load a C++ driver / create C# interface : DONE.

Driver

  • Implement user controlled vehicle : DONE.

User interface

  • Port to MyGUI's C# interface : DONE.

Merging Imre's work

Order:

  • Identify hardcoded stuffs : WIP
    • openracing.in -> LD_LIBRARY_PATH=/home/mulder/projects/openracing/cleaned/src/libsimulator/.libs
    • src/ode/OdeLoader.cs -> mCtx.RegisterResourcePath("/home/mulder/projects/trunk/track/Barcelona/");
    • my_config doesn't have to be in the repository
    • src/core/RaceManager.cs -> InitStartingGrid
    • src/graphic/OScene.cs -> mCtx.RegisterResourcePath("/home/mulder/projects/openracing/cleaned/data/tracks/road/icy");
    • src/ode/OdeMesh.cs -> XmlTextReader reader = new XmlTextReader("/home/mulder/projects/openracing/cleaned/data/tracks/road/icy/Mesh.mesh.xml");
  • Full merge
  • Clean
