torcs-users Mailing List for TORCS - The Open Racing Car Simulator

Hi all.

I am trying to obtain the semantic segmentation map of front-facing camera
view image.

Since TORCS renders front-facing camera view images in real time,

I think it is possible to know which pixels (in the front-facing camera
view image) correspond to the road or which pixels correspond to opponent
car.

Does anyone know how to obtain such information from TORCS?

Thanks.

Hello all,


Is there a way, or rather what would be the prescribed way, to get race video not for recording purposes but as live images from the perspective of the autonomous car and its virtual front/top view camera? Readout would be at much lower frequency than regular screen rendering refresh rate. Reading through the API doc, there are somewhat related screenshot to a file methods like GfuiScreenShot, but is there a cGrCamera related method that directly returns in memory 2D bitmap? In the same vein, is there also a way to access (readonly) 3D data centered around car's pose that respective camera view is rendered from?


Best,

Pedja

Hi everyone,

I use TORCS to emulate sensor data for an autonomous driving application
for my master's thesis.
With the renderings from TORCS I emulate a visual sensor that responds to
brightness changes rather than absolute values. Unfortunately it struggles
with the tree textures a lot, it just creates loads of noise and I would
really appreciate it if someone could direct me to how to best remove trees
and treelike textures from a track. There are some tracks without trees,
but unfortunately they are almost without any other structures too, and
some structures I do need.
I found some topics related to this question but the interesting links were
broken and I also tried modifying some .acc files of tracks but just ended
up breaking them.
Your help is very appreciated, thanks already in advance.

Cheers,
Konstantin

I can login to the CVS using the command provided on the Torcs website, but
upon checkout I get this error message:

$ cvs -z3 -d:pserver:ano...@to...:/cvsroot/torcs co
-r r1-3-1 -P torcs
Fatal error, aborting.
anoncvs_TORCS: no such system user

I am not familiar with CVS, but is that a server-side issue?

Hi everyone,


I'm currently developing a bot using the SCR-server but I need to draw the trayectory of the car through the track (in a graph) and so far, I have only found how to get the current X and Y coordinates of the car (car->_pos_X/car->_pos_Y). With that, I think, I can effectively draw the trayectory of the car but I have one problem: I don't know how to draw the track in a graph and that the obtained x,y coordinates of the car relate appropiately with the track (like drawing over a map).


I've seen a function in the robottools.h file that is called "RtTrackLocal2Global" which from what I understand, recieves a local position (segment, toRight, toStart) and converts it to a global position (x, y coordinates). I was thinking that I could call this function and manipulate the toRight value to get the coordinates of the borders of the track while driving (calling the function inside "drive(int index, tCarElt* car, tSituation *s)") and with those, draw the track while also plotting the trayectory of the car.


I'm not that good in C++ and the function recieves as inputs a bunch of parameters that I don't know how to get or manipulate (tTrkLocPos *p, tdble *X, tdble *Y, int flag) to call the function. I'm even more confused because the function returns void so I don't know where to get the x, y coordinates.


I'm sorry for the long post but, can someone tell me how to get the input parameters for the "RtTrackLocal2Global" and how to get the resulting x, y coordinates? Or if there is an easier way to draw the map so I can draw the trajectory of the car over it, I would appreciate if someone could explain it to me.


Also sorry for my subpar English.


Best regards,

Hi all,

I want to delete drivers from driver list.

As all of you know, when we choose "Configure race" button, we can move to
drivers selection page.

There are a lot of pre-installed drivers in the list. For example, damned1,
damned2, ....

I would like to delete those drivers from the list forever.

Please help :)
