Re: Converting track XML into something playable (.ac files, especially)

Cool, interesting, did you read the thesis of those guys (have a look 
into "about"):
http://trackgen.pierlucalanzi.net/

Maybe you refer to another ac file in the xml (e.g. the optional 
relief?), no idea, what is the console output if you run it from console?

If you compiled from source with Visual Studio newer than 6.0, there is 
an issue with wrong fopen parameters, which cause an exception. If you 
run it under Posix like systems or the binary distribution (which is 
still built with vc 6.0) then trackgen should work with a correct xml file.

Use trackgen -h for help:
Usage: trackgen -c category -n name [-a] [-m] [-s] [-S] [-E <n> [-H <nb>]]
        -c category    : track category (road, oval, dirt...)
        -n name        : track name
        -b             : draw bump track
        -B             : Don't use terrain border (relief supplied int 
clockwise, ext CC)
        -a             : draw all (default is track only)
        -z             : Just calculate track parameters and exit
        -s             : split the track and the terrain
        -S             : split all
        -E <n>         : save elevation file n
                          0: all elevatation files
                          1: elevation file of terrain + track
                          2: elevation file of terrain with track white
                          3: track only
                          4: track elevations with height steps
        -H <nb>        : nb of height steps for 4th elevation file [30]
        -L libDir      : Library directory

And maybe this helps:
usuarios.multimania.es/f1torcs/
and
http://torcs.cvs.sourceforge.net/viewvc/torcs/torcs/torcs/doc/tutorials/track/index.html?revision=1.2&pathrev=r1-3-1

If this does not help, please post the console output of trackgen, maybe 
this gives a hint. If there isn't anything interesting you could as well 
build a debug version of trackgen and have a look with the debugger why 
it fails or post the track xml, then I could have a look when I find the 
time.

Do not forget to show us the result then;-)

Best regards

Bernhard
