Track files and formats

VDrift's tracks are composed of 3D-modeled objects in .JOE format, PNG graphic files for textures, and text files describing the objects and track.

Files

The files that define each track are within the data/tracks/trackname/ directory, where trackname is the "short name" of the track.

about.txt

Simple text file with the track's full name as the first line. Credits may be on following lines.

roads.trk

This file defines the road surface for the track. It is generated by the track editor. Following is the format of this file:

<number_of_roads>
<number_of_Bezier_patches_for_the_1st_road>
Control point coordinates of Bezier patch 1 (total 16 points)
Control point coordinates of Bezier patch 2 (total 16 points)
.
.
.
.
<number_of_Bezier_patches_for_the_2nd_road>
Control point coordinates of Bezier patch 1 (total 16 points)
Control point coordinates of Bezier patch 2 (total 16 points)
.
.
.
.
<and so on>

trackshot.png

This is a 512x512 PNG graphic file that is displayed in the menu when selecting the track to race on.

track.txt

This file defines various track parameters. This file is in VDrift's Configfile format.

objects/*.png

The PNG files have names corresponding to the object they belong to. These are the textures for the 3D model objects that make up the track.

objects/list.txt

This is a plain text file that defines the relationship between objects and textures, and also sets object properties. It is generated and edited with the Listedit tool which is part of the Track editor tools.

A description of each field in the list.txt file can be found at the following location: http://svn.vdrift.net/viewvc.cgi/trunk/listedit/format.txt?root=VDrift+Track+Editor&view=co

objects/objects.jpk

This file contains all the files that define the 3D models for the objects that make up the track. It is in the JOEPack format, which contains many files in the JOE format.
