Hi list,

I am an editor at the German Linux Magazine, and if somebody is interested in this topic, the 
Magazine might be very interested in publishing an Linux-open-source-know-how-article on that - I 
assume... :-) Perhaps an author could elaborate on other engines, too?

If you're interested, send a mail to: mfe...@li... - I will reply!

BTW (if I remember right) the May edition of the "Linux User", also one of our german Linux-based 
magazines, will have a longer article on Torcs! I'll keep you updated once an english version will 
be published.

:-)

Hi everyone,

I was wondering if anyones done some study on how accurate e physics  
modelling in TORCS is compared to, for example Racer.

I found some uni research n projects that use TORCS n was wondering if  
that's more cos it's GPL rather than because it's got more accurate  
modelling.

Cheers!

Hi,


I've output the 4 wheels' speed data (rad/s) into an excel and plot out  a 
graph based on the 4 sets of data.
I have noticed something strange.

When accelerating to reach a constant speed of about 53kmhr on asphalt-2 
road, 
speed of the back wheels exceeded the front wheels by about 0.5 rad/s.

Could someone help to answer what might have caused this behaviour?


Thanks.

In OpenSuSE it is freeglut-devel, but that (along with all the other -devel packages) was the perfect solution.

IMO, this should be clarified on the download/installation page.

Thanks for the help!

Have you installed also the -dev package of freeglut? Under Ubuntu it's 
named freeglut3-dev.

 I am wanting to use the robot development tool for my honours project at University to discuss racing AI techniques, however I am having a few linker problems.

First of all I couldn't find libc.lib, found that and then had several "already defined in libcmt.lib"  I used /NODEFAULTLIB:libc in the Linker properties which removed this, and the need to have the libc.lib file in my export\lib folder, however it has given me a new error: 

1>libpng.lib(gzio.obj) : error LNK2019: unresolved external symbol _errno referenced in function _gz_open

 
 
all of these errors have been to do with the client project with the torcs source.

FYI I am using Visual C++ 2005 express on a Windows 7 machine

Any help will be greatly appreciated

It smooths some variables from one time step to the next.
There is a #define somewhere

Hmm...I've found out that it's used also by inferno2.cpp, common.cpp, 
grboard.cpp, robottools.h, grcam.cpp, but I don't understand it's use....

Hi, 


I've been trying very hard to Google about RELAXATION and RELAXATION2 
function in wheel.cpp, yet still unable to figure out what is the main 
purpose of using it in SimWheelUpdateRotation function. 

In this function, 3 parameters are needed: target, prev, rate. 

Could someone help to answer my questions? 

Thanks.
