Well - in the TORCS track format you specify the heights and then it gets interpolated, so it's not infered from the terrain. Rather the terrain is matched up to the track. You can supply open polyline meshs (ac3d format) to the terrain generation phase to get some control over the terrain but that is hardly a bitmap. You could probably convert the bitmap into the required inside and outside relief ac3d files. If you want to have a quick play with the track format, I suggest you get the track editor from
http://katergo.rege.org/projects/trackeditor/There is a manual inside the tarball. You will need Java installed and operational. The instructions you have read are tricky to decipher if you haven't actually followed through from start to finish. The track editor does make certain things clearer.Cheers,Toby Haynes
