JointedLine

I needed an easy way to draw and modify jointed lines in one of my projects. I wrote this small proof of concept just to test the algorithm.

The goal was to make it easy to add, insert and move joints.

Hint: Everything in this example is pretty basic. The interesting part is when you insert a joint on a line.

Example usage

• Left click on an empty space to append a new joint.
• Left click on a line to insert a new joint on that line.
• Hold down left mouse button to drag joints.
• Right click on a joint to delete it.
• Press SPACE to toggle visual joints.
