This might help you You probably want to treat these as generalized cylinders and tessellate a triangle mesh. This can be done by sweeping a circle along the path. Some of the details are tricky since undefined tangents can lead to unexpected twists in your triangle mesh. You might want to study the GLE library or the TubeGeometry implementation in ThreeJS.
For simplestic rendering, note that OpenGL has GL_LINE_STRIP. It also has glLineWidth, although many platforms have a max width of 1. You would need to take care to use separate draw calls for seperate springs, otherwise they'll be connected.

I wish did fix the issue. We use Tenacity for this (also known as "Polyglot Persistence"). It works really well, though there are some limitations. The owner/maintainer, JWood, is very responsive and has fixed bugs and merged in pull requests I've sent very quickly.

this one helps. What you're basically arguing for is the extender pattern. You're right that not everything is best represented as a Java object implementing a service interface. Some contributions are best offered as static or declarative resources in a bundle.
The Eclipse Extension Registry is essentially just an instance of the more general extender pattern. DS and Blueprint are examples as well. You can implement the extender pattern yourself pretty easily with portable OSGi APIs, such as BundleTracker. Also make sure you take full advantage of the Provide- and Require-Capability headers, to make sure that your extender actually gets picked up and installed by a resolver.

I think the issue was by ths following , Here is an O(n) solution.
Let S be the set of points. Let p be the leftmost point of S. Then p is on the convex hull of S. Let q be the point of S minimizing the angle between the ray going to the left from p and the ray starting at p and going through q. Both p and q can be found in O(n) time. The segment pq is an edge of the convex hull of S and no point of S lies to the left of the line pq.
