Questions

When evaluating software, quality is 50%, and community is 50%.

In general we should be looking for the biggest community. The one with 2x as many developers will win, unless both have achieved critical mass.

Any codebases we use we will want to be able to program in a Mono language. (Reasons for this do not fit into the margin) Finding managed bindings is a part of the development.

Codebases

NASA Robotics code

http://www-robotics.jpl.nasa.gov/news/newsStory.cfm?NewsID=69

http://claraty.jpl.nasa.gov/man/software/modules/algorithms/index.php

Let's put this code in our repo

GNU Scientific Library

All C, but so big it gets its own section: http://www.gnu.org/software/gsl/

We could use this code as a source for us.

Huge reference of everything about games

http://www.gamedev.net/reference/

Math (Wolf-Dieter)

Requirements

Here is a set of math functions that the torcs robot needs. http://keithcu.com/wiki/index.php/Image:Unitlinalg.cpp

We also need support for splines. The code above doesn't use operators, and our code should to be more natural-looking. We should be binary compatible with torcs, and we can change it to match our data structures.

We also need neural network code for some learning required by the driving robot.

AForge AI Library written in C#

Math, Image processing, neural networks, machine learning, and vision. (We won't be using his vision code...) There is a decent amount of traffic on the forums, and the releases have thousands of downloads. The guy is from Latvia and has linked-in profile says he is looking for consulting work: http://www.linkedin.com/pub/4/410/A72

http://en.wikipedia.org/wiki/OpenCV

Found a .Net wrapper! http://code.google.com/p/opencvdotnet/

To get it to work with mono, use the opencvdotnetnewcore directory

Intel's code written in C++ in 1999-2000. Not too much going on with it, but it was used by Stanford in the Darpa Grand Challenge. It has code that should be thrown away, but it is comprehensive. I think we should start with it, especially that there is a .Net wrapper

Game libraries

(Jeko) Mono Tao Framework http://taoframework.com/

Ogre

Ogre: http://www.ogre3d.org/ A good and popular one with a big online community. Used by many "serious" project, it is well documented. A friend of mine worked with and recommended it.

http://www.ogre3d.org/wiki/index.php/OgreDotNet (Supports mono, not that used)

http://www.ogre3d.org/wiki/index.php/MOGRE (Popular, doesn't support Mono)

Huge list of Ogre Links

Physics Engines

The physics engine we will use is likely this: http://www.ode.org/

There are .Net wrappers we will use so we can program in C#: http://sourceforge.net/projects/odedotnet

Physics Simulations

PlayerStage

We also need a physics simulator GUI to play and step through simulations. Here is a robot simulator: http://playerstage.sourceforge.net/index.php?src=gazebo

Monobotics Robotics (and Vision) Simulation GUI

http://www.monobotics.ic.uach.cl/

Removed from consideration

Open Scene Graph

http://www.openscenegraph.org/projects/osg/wiki/About/Introduction

http://www.openscenegraph.org/projects/osg/wiki/Community/LanguageWrappers

I've been using openscenegraph for 2 years (that was 2 years ago) and it has been a pain! Lack of documentation and a few bugs. However it is quite popular, it is still not very mature. Its good points however: there are many import of 3D formats supported and it offer good real-time performances.

Jag Engine

http://www.jadengine.com/index.php?title=Main_Page

All in C#, but going through a rewrite, and they don't have a community yet.

Delta 3-D

Delta 3-D http://www.delta3d.org/

Small community

PLIB

Portable game library: http://plib.sourceforge.net/whats_inside.html Features: sound effects, music, a complete 3D engine, font rendering, a simple Windowing library, a game scripting language, a GUI, networking, 3D math library and a collection of handy utility functions. Each library component is fairly independent of the others - so if you want to use SDL, GTK, GLUT, or FLTK instead of PLIB's 'PW' windowing library, you can.

This is a cool component for people making simple games, but we don't need most of it, and the stuff we do need isn't that powerful or popular. Torcs uses it, but that will change :-)

Irrlicht

Irrlicht: http://irrlicht.sourceforge.net/, also has .Net bindings

http://irrlicht.sourceforge.net/phpBB2/viewtopic.php?t=18125&highlight=

http://www.blitzbasic.com/Community/posts.php?topic=73978

Looks like a good engine, but some have complaints about it: it is less pluggable, less powerful, etc.

Axiom Engine

http://axiomengine.sourceforge.net/wiki/index.php/Main_Page This is a port of Ogre that is clean, rich, and supports Mono. It doesn't have the community of Ogre and Irrlicht. Using a native C# component is awesome, but using something with a community is more important.

Mono Xna

http://code.google.com/p/monoxna/

This is missing a lot

Racer.nl

http://www.racer.nl/, nice looking, source code available but not open source (restrictive license). (Website is down...)

Ultimatestunts.nl

http://www.ultimatestunts.nl, require art work to look better. The track format supports junctions. There isn't as big a community as around Torcs.
