Tubes in the example represent walls. And lines
In my app, the user is able to draw each wall from scratch, so he decides whether to start drawing clockwise or counter-clockwise.
I need to change the
parallelLines function so that the parallel lines are always on the outside, no matter what direction the walls are drawn.
Because currently the function works for 1 direction only. In the example, you can see that even though I use the
outerPoints, the lines are drawn in the inside side for the 3 tubes. Thats not what I want.
I hope this makes sense. Let me know if you need clarification.
