A set of circles animates continuously, with positions influenced by a Delaunay triangulation derived from a set of points. The rendering uses a Canvas element and the d3-voronoi library to compute the triangulation, while d3.forceSimulation likely drives the point movement. The visualization updates each frame, showing the evolving geometric relationships between the moving circles.

Delaunay Circles II

A field of points connected by Delaunay triangles animates in a loop, with each triangle’s interior filled by a circle whose radius grows until it touches the triangle’s edges. The canvas redraws every frame, shifting point positions via a time-based function to continually recompute the triangular mesh and its inscribed circles. The visualization uses the `d3-voronoi` library for the Delaunay triangulation and draws directly to a 2D Canvas via JavaScript, with animation driven by a simple time step and no external data source.

Delaunay Circles

A field of randomly walking points forms a continuously updating Delaunay triangulation. Each triangle in the mesh contains an inscribed circle, with the circles rendered in a dark color against a light background. The animation runs on an HTML canvas, with the Voronoi and Delaunay calculations handled by the d3-voronoi library, while the points themselves are displaced using a simple random-walk algorithm. The code demonstrates the geometric relationship between the triangular mesh and the inscribed circles, which change as the points drift across the viewport.

Voronoi Circles

Voronoi Circles uses D3’s Voronoi tessellation to partition a canvas into regions around moving points, with each region filled by a colored circle that pulses and shifts in size. The animation, rendered with the Canvas API, computes the Voronoi diagram via `d3.voronoi` and updates the drawing each frame. The example demonstrates how Delaunay-based spatial subdivision can drive a simple, rhythmic visual effect.

Delaunator

Delaunay triangulation is computed continuously over a set of moving points, with red points fixed at the start and blue points added via mouse movement. The canvas animates as points drift randomly, and the triangulation updates every tenth of a second. The visualization uses the Delaunator library for fast triangulation, with d3.v4 for scaling, intervals, and event handling, and Canvas API for drawing the filled triangles.

Delaunay Triangulation

This interactive demonstration shows a Delaunay triangulation of 100 randomly generated points, with triangles and links redrawn in real time as the user moves the mouse. The first point follows the cursor, highlighting all triangles and links connected to it in red and white. Built with d3.v4 and the d3-voronoi API, it uses SVG paths, lines, and circles to render the triangulation, updating the visualization dynamically on mousemove and touchmove events.

delaunay-triangulation

This interactive visualization demonstrates the Delaunay triangulation of a set of points, rendered as an animated SVG using d3-voronoi. As users drag points, the triangulation updates in real time, with the SVG paths redrawn to show the current triangular mesh connecting each point to its nearest neighbors. The animation highlights the dynamic nature of the Delaunay triangulation as point positions change.

Delaunay Force Mesh III

This visualization shows a force-directed mesh of points initially distributed via Poisson-disc sampling, with a Delaunay triangulation overlaid as connected gray lines. A fixed root node is pulled by mouse movement, while all nodes gravitate toward their original sample positions. The code uses `d3.layout.force` for the physics simulation, `d3.geom.voronoi` to compute the mesh links, and renders the result on a Canvas via the `getContext("2d")` API. Each tick redraws the links and nodes, with points styled as white-stroked black dots.

canvas circles

The visualization displays a grid of randomly colored circles that continuously appear and expand across the screen. It shows a generative animation where each frame introduces new circles at shuffled grid positions, growing from zero to full size before fading away. The code uses D3.js with SVG elements, leveraging transitions to animate circle radius and removal. Rendering depends on the d3-starterkit and d3-jetpack libraries for concise element creation and data binding. Colors are randomly generated RGB values applied to fill and stroke. The animation runs indefinitely via recursive setTimeout calls, creating an evolving, ever-changing mosaic of overlapping rings on a dark background.
