/3/ - 3DCG

I got a mesh to stay within the boundaries of an edge. Conceptually, both endpoints of the edge have a sort of "plane" attached. Those two planes are infinite in scale. The angle of the planes are perpendicular to the angle of the edge. So I manipulate the edge using bones. Which in turn moves the planes. And the cylinder between the planes can't escape. The cylinder can move freely between the two planes, but when its tries to go outside the bounds, it squashes against the plane instead.
