IDEA: Auto draw 2 lines about 1 inch apart & curve around but not overlap.

(1/3) > >>

dartgame:
Hi,

I'm after program that will automatically draw two thin lines about one inch apart. The lines would curve around randomly and parallel but not cross over previously drawn lines and would eventually return to the starting point and join up. Varying the length would also be desirable. Outside the lines should be white and inside the lines should also be white. I want to be able to print off the results after enlarging it with a paint program. In effect, it will be a racetrack for my sons Hot Wheels cars.

Hope this is practical.

Cheers,

I reckon the easiest way to do this is with a vector programme -
Inkscape is open source/free, will probably do the job.

Draw one line, make it a heavy line.
Then duplicate it/clone it - but make the second line thinner and make it white.

The result will be like this:

if you want, I could produce a vector PDF for you -
but give me some more details.
I can make it any size you want - in the latest Adobe Reader (version 'X') you can print an extra large image on as many pages as it needs -
you get a bit of a jigsaw puzzle after :)

you may want an app similar to this demo ?

this seems a nice project to make a procedural river/racetrack generator with "surprising outcomes" as explained by mouser on his post about coding something emergent

The input of such program could be:
-number of curves
-distance
some code useful to make bezier interpolations:

I encourage anyone to try to make this project  ::)
