GPL Track Creating - Creating a TRK

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:
Traces
These are lines going all the way round the track, parallel to the centre-line. The Altitude curves follow these lines.
Sections
Your track will be constructed from sections - a combination of straight and curved pieces (the curved pieces are arcs of a circle).
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.
Altitudes
Flat tracks are okay, but hilly tracks are more fun. Altitudes are cubic functions defining the height of each Trace, per Section.
