Custom CSS and JS
Custom CSS Plugin for Visual Studio Code. Based on vscode-icon
Custom CSS and JS is a Visual Studio Code extension that allows users to inject custom CSS and JavaScript into the editor interface, enabling deep visual and behavioral customization beyond what standard themes provide. The tool works by modifying VS Code’s internal styling system, allowing developers to override UI elements such as fonts, colors, spacing, and layout with their own stylesheets. This makes it possible to create highly personalized development environments tailored to individual preferences or workflows. In addition to aesthetic changes, users can also inject JavaScript to modify certain UI behaviors, effectively extending the editor’s functionality in unconventional ways. The extension is often used to implement custom themes, improve readability, or experiment with alternative interface designs. However, because it alters internal files, it may require reapplying changes after updates and can raise stability considerations. -

Delaunator
Fast JavaScript library for Delaunay triangulation of 2D points
Delaunator is a fast library for Delaunay triangulation. It takes as input a set of points. The triangulation is represented as compact arrays of integers. It’s less convenient than other representations but is the reason the library is fast. After constructing a delaunay = Delaunator.from(points) object, it will have a triangles array and a halfedges array, both indexed by half-edge id. What’s a half-edge? A triangle edge may be shared with another triangle. Instead of thinking about each edge A↔︎B, we will use two half-edges A→B and B→A. Having two half-edges is the key to everything this library provides. It will also be useful to have some helper functions to go from one half-edge to the next and previous half-edges in the same triangle. We can draw all the triangle edges without constructing the triangles themselves. -
