View source for GPL Track Creating - Creating a TRK

''Authored by the GPLEA''



===GPLTrk===
 
GPLTrk is the program used to create TRK files.  It has been designed to work with GTK files, so you cannot load TRK files, only export a TRK for use with trk23dow/GPL.   

Your GTK/TRK consists of 4 sections: 

===1) Traces===
 
These are lines going all the way round the track, parallel to the centre-line.  The Altitude curves follow these lines.

===2) Sections===
 
Your track will be constructed from sections - a combination of straight and curved pieces (the curved pieces are arcs of a circle).

===3) Walls===
 
Walls is the term used to describe the way each Section is broken down. These walls are all the flat regions of the track: asphalt, grass, banking, concrete; as well as all the real walls: armco, hedge, rows of people, etc.

===4) Altitudes===
 
Flat tracks are okay, but hilly tracks are more fun.  Altitudes are cubic functions defining the height of each Trace, per Section.
