Voronoi 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 III

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.

Voronoi Spirals

Randomly placed points generate Voronoi cells that gradually spiral inward, cycling through a Cubehelix color scale over a five-second animation. The d3-voronoi layout computes the initial polygons, then each frame the code shifts a vertex and interpolates a new point along each cell’s first edge, closing the path and filling it with a color based on elapsed time. Rendered on a Canvas via the d3.timer API, this creates a continuous, organic morphing effect.

Rotating Distance-limited Voronoi - d3v4 - canvas

The example shows a rotating set of distance-limited Voronoi cells rendered on a black canvas, where each cell’s maximum radius shrinks and expands over time. It updates the limit dynamically using a cosine function, redrawing the cells each frame via the `d3.distanceLimitedVoronoi` plugin and the Canvas 2D context. Points are generated from animated circles with varying radii and angular speeds, and the code uses `d3.timer` for the animation loop.

Canvas Voronoi

One hundred randomly placed sites form a Voronoi diagram, rendered to a Canvas element. The cell containing the mouse position is filled red, while all cell boundaries and links between neighboring sites are stroked, and each site is drawn as a small circle. The first site follows the pointer via `d3.mouse` on touchmove or mousemove. The example uses `d3.voronoi` to compute cells, links, and polygons, with Canvas 2D context methods like `arc`, `moveTo`, and `lineTo` for drawing.

Voronoi Spirals II

A Voronoi diagram partitions a canvas into cells around randomly placed sites; this animation continuously warps those cells by rotating each polygon's vertices, creating a swirling, spiraling effect. The fill color shifts through a smooth spectrum as the animation progresses over five seconds. The code uses d3.voronoi to compute the polygons, d3.timer for the animation loop, and d3.scaleCubehelix to interpolate the cell colors. Each frame, the first vertex of a cell is moved toward the next, shortening the polygon's edge before pushing a new point into the array. The rendering is done via the Canvas 2D API.

Canvas Voronoi

This example visualizes a Voronoi diagram of 100 randomly generated points, with the cell containing the mouse position highlighted in red. As the cursor moves, that site and its cell update in real time. The diagram is rendered entirely to a Canvas 2D context using the d3-voronoi API, computing both cell polygons and Delaunay links. The code draws all cells with black strokes, site markers as small circles, and semi-transparent link lines, demonstrating how d3-voronoi outputs geometric data suitable for immediate canvas drawing.

Rotating Voronoi in colors

Dozens of colored points orbit along concentric circular paths, while the Voronoi cells surrounding them are resampled and smoothed into curved, lens-like shapes that continuously rotate and morph. The animation is rendered as an SVG, with each cell’s fill and stroke sampled from a two-color linear scale. The code uses d3.geom.voronoi to compute cells, a basis-closed line interpolator for curvature, and d3.timer to drive the point motion and redraw the paths.
