road tracing

[alex25]

while playing with yet another track conversion i ran across an interesting problem. the track itself is modeled as two sections. most of the time they are at the same bank angle and thus could be modeled as one but there are parts where the two sections have different bank angles and if i were to trace it as one section the traced road will be above (or below) the real road. this is a picture of the turn where this is most noticeable:



some of the problems i am having with having the sections traced separately:

you can clearly see two racing lines. i wish there was a way to combine them. if i were to have an ai car race along i am not sure what racing line it would be supposed to follow.

lap sequences don't work. i tried choosing 4 sequences, 2 on each road but it didn't help. but this problem is more general as if i were to choose one lap sequence at the starting grid and then go through the pit vdrift wouldn't think i completed the lap even though i did. maybe we should consider a more generic mechanism where we can extend the lap sequence past the traced road somehow.

anyway this is sort of academic since i don't have permission to release this particular track but the above problems are more general.
