thelusiv Wrote:My theory about the bumpiness is that sometimes, if you use the "auto-select the next 25 roadway pieces" feature in the track editor, it sometimes chooses the same set of points but reverses them. Then it continues. This creates a "bump". I haven't thoroughly tested my theory...but you could if you like. Just go around and select the track pieces one by one, use the single auto find function and observe it as you go. If you auto grab a track segment, but you don't see the next square of track light up, press backspace to delete it and do it manually. If this causes all the bumps to be gone then we'll know that is the problem...
i traced manually one of the corners where i see this bumpiness and, indeed, there is a difference between the two tracks in two places (there are two places around this corner where i see the bumpiness, one at the entrance and one on exit). i put the files at
http://caliban.lbl.gov/vdrift/tracks/pau/ as roads.trk-old (the version that's in svn) and roads.trk-new. roads.trk.diff is the diff file (in unified format). unfortunately i don't understand the format, each 4 vertex rectangle has 16 entries and in both cases only one group of 4 is different while the other 3 are the same. can somebody shed some light on this format? i wonder if this helps.
unfortunately, this is not it. looks like the extra entries are some kind of interpolation. if i select some more rectangles at the beginning and the end of the track segment there is no difference (except for the extra rectangles) between the manually selected track and the old one (which might or might not have been selected automatically). maybe the interpolation is wrong.
