Congrats! Seems we would have swept path analysis on FC very soon ? :D

Just sayin'... ;)

As for the 3D traffic sim, there's a surprisingly large number of them. I've even seen one designed for Unity3D. It's good to see an option for Blender, even if it is proprietary. The price is quite reasonable.

It's certainly something that could be written in FreeCAD... What would be nice would be a good quality open source simulation modeller engine that could be hooked to any front end...

I'll put it on my to-do list. ;)

Congratulations!

P.S. Looks surprisingly easy to understand, where did all the complexity go?

I'm trying like crazy to figure out what you're referring to....

So... what are you referring to? :lol:

Well, all this discussions in the past, examples, prototypes ... All looked rather complex and involved. Now i guess people just have to say OK, vehicle, here is the trail. And everything else happens automagically.

Well, with swept path analysis, it is fairly straightforward. The complexity is in vehicle design and the math to produce an accurate analysis. For the user, though, they really need to do three things: provide a roadway drawing, a design vehicle, and a path to follow.

Actually, just watch the animation here. That pretty much describes the complexity for the user:

Gratuitous thread-bumping...

Now we're making tracks. ;)

Nice to see the progress. Looking forward for trailer management.

That's next. Then I need to work on developing the outer envelope (merging the outermost tracks where one exceeds another)
