long beach track project

[samsepi0l]

Rather than post in another thread, I though I'd create a specific thread to the long beach rebuild I started.

I am attempting the 1991 circuit config first. Here is an aerial view of the 1991 layout

Those extra corners before the back straightaway are more interesting than I thought. I think you've created a map that is more accurate than any diagram I've seen on the Internet, and in fact I have an old Long Beach event program that is also inaccurate, because they assumed it's all 90 degree corners. But watching the broadcast for the several years up to 1991, you can see there is a fast double apex left hander there, which you have depicted accurately.

Is it possible to make the final hairpin as it was in real life not as it appears in the game?

you mean super tight and not a big constant radius wide corner?

I hope so.

I have my SG file done, and I converted it to trk/3d and 3do

I am not sure what will happen and how much wider it will have to be to avoid warping.

On the SG file through the hairpin I have the "centerline" of the SG very close to the outside of the corner near the wall. Checkpoint10 actually put the centerline outside of the drivable section of the track when he did Nashville so he could get much tighter corners. He was able to avoid warping this way- so you can get tight corner geometry. We think this may be why you can't quality in nashville though- since the cars appears in spots outside of the track drivable surface.

I will do some testing and see if I get warping before moving onto objects.

I did some calculations based on checkpoint10's calculations. The center line in the design I have is more than 80ft apart- which seems to be the number where if you get closer than this- warping will occour.

I am hopeful I can learn from his experiences that this will NOT warp. I don't know yet. I may need to widen up the corner more.

Here you can see the "REAL" gps track geometry, and the SG file.  My hairpin is not exactly as tight as real life- but it is WAY tighter than the papyrus version (I previously overlayed the papyrus 3do and my 3do - it's a big difference)

You can see my walls- and I highlighted my "centerline" with a yellow marker.

Even if you approach the right side of the hairpin- you are still closer to the center-line on your left.

The center line on the exit of the hairpin is more than 80 feet from that on the entrance.



I would love to know more what Pavel thinks about this. If this works I owe major credit to checkpoint10 for the research he did in nashville. I can only image the time he spent testing SGs!!!!

And here are my sketches to Long Beach base sg file https://drive.google.com/drive/folders/1...share_link
I didn't move farthere because I want to find some elevation data.

Samsepi0l, first of all from this picture hairpin section has wrong layout, I think. You have two parallel sections connected with 180 degrees corner section. But section shouldn't be parallel so the corner section should be less than 180 degrees. Also to have centerline on the outside is bad idea. I'm sure you will have problems with AI at hairpin. Also then first chicane also will be with with centerline on the outside and it's also bad idea. It's better to keep centerline in center or at least move it to the right but not to the left. I think if Long Beach will have same hairpin radius as my old Vancouver track then it should be enough.

The outside centerline was only for the hairpin. It slowly moves back to center after you exit the corner. Throughout the track I do not have the SG file perfectly centered- but it is relatively close everywhere.

I will take a look at your SG file- thank you.

I watched the F1 track with the ups and downs. That was a surprise.

guys I have not stopped working on this, I'm just not as free lately because of work- (just wanted to provide an update for all of you!)

It's funny how much faster I am now compared to when I built Denver....
