This example demonstrates a distance-limited Voronoi cell, showing the intersection of a Voronoi cell with a circle around a central seed. Users can drag the seeds or the radius anchor to interactively update the highlighted region. The visualization uses D3 v4’s `d3.voronoi()` for layout and a `d3.path()` context to compute the limited-cell path via canvas-like directives, rendering the result as SVG with draggable circles.

AI-generated description

This block is a continuation on my reflexions on Distance-Limited Vornoi Interaction (see 4, 3, 2, and 1).

This block experiments how to compute the path of a distance limited vironoï cell, which is the intersection area of a d3 Voronoï cell and a circle.

Compared to the previous block, the algorithm uses a d3-path context and its canvas-like directives (instead of producing a svg-compatible string).

path for Distance-limited Voronoi cell - d3v4

This interactive D3.js v4 example visualizes a distance-limited Voronoi cell, showing the intersection between a standard Voronoi polygon and a circle centered on one of its seeds. Users can drag the seed points or the circle's radius handle to update the layout in real time. The code computes the Voronoi polygons via `d3.voronoi` and traces the clipped cell path with a custom line function, rendering the result as SVG paths with interactive drag behaviors.

path for Distance-limited Voronoi cell

This example visualizes distance-limited Voronoi cells by intersecting each Voronoi region with a circle of adjustable radius. It shows how a cell's boundary changes as seeds or the radius are dragged, highlighting the clipped path where the cell meets the circular limit. The implementation uses D3 v3’s `d3.geom.voronoi` layout and `d3.svg.line` to compute and draw cell paths, with `d3.behavior.drag` enabling interactive updates to seed positions and the maximum cell distance. Rendering is SVG-based, with circles and paths styled via CSS classes.

d3-voronoi.clipCircle

This example demonstrates a Voronoi tessellation clipped by a circular boundary that follows the mouse cursor. It shows how to programmatically clip Voronoi cells to a circle, rather than relying on browser-level clipping, with the clipping circle moving interactively as the user drags. The algorithm computes segment-circle intersections and constructs a path using lines and arcs, blending d3.line with curveCatmullRomClosed. Built with d3.v4, it uses d3.voronoi, d3.scaleOrdinal with d3.schemePastel1, and renders 100 randomly placed sites as SVG polygons and circles.

Voronoï playground : Do you see the path ?

The example reveals emergent path-like structures within a Voronoï tesselation by generating cells whose borders align along a user-drawn route. Viewers click and drag to create a continuous white stroke, and the visualization dynamically seeds limited-distance Voronoi cells around that path, coloring and styling each cell border to suggest a coherent corridor. Built with D3 v4, it uses `d3.drag`, `d3.line`, and a custom `d3.distanceLimitedVoronoi` plugin to recompute cells in real time, with an SVG filter applied for visual saturation.

Voronoï playground : Do you see the path ? (II)

This interactive Voronoi playground reveals hidden paths that emerge from the smooth chaining of cell borders. Users can draw their own path by clicking and dragging, or select from predefined paths, which are then used as constraints to generate Voronoi seeds scattered near the path’s trajectory. The resulting cells are rendered as cyan outlines, with a white, blurred stroke tracing the original path and highlighting the emergent route. Built with D3 v4, it uses `d3.voronoi`, `d3.line`, and `d3.drag` to update the tessellation in real time as the path changes.

d3-voronoi.clipCircle

This interactive visualization demonstrates how to programmatically clip a Voronoi tessellation to a circular boundary using d3.voronoi and custom geometry routines rather than relying on the browser’s screen-space clipping. As the user moves the mouse, the first site follows the pointer, dynamically recomputing the diagram and redrawing all polygon paths with a clipped `d` attribute. The code uses SVG, D3 v4, and functions like `segmentCircleIntersections` and `largeArc` to compute arc segments, with site positions generated from a random polar distribution inside the circle.

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.

Rotating Distance-limited Voronoi - d3v4

The example visualizes a rotating set of points whose Voronoi cells are limited by a dynamic maximum distance, creating an evolving pattern of filled polygons against a black background. It revisits Mike Bostock’s original rotating Voronoi using the `d3.distanceLimitedVoronoi` plugin, which recomputes cell boundaries at each animation frame based on the shrinking or growing distance limit. The code uses two `d3.timer` callbacks—one to update point positions via trigonometric motion and another to adjust the `limit` value—while rendering SVG `path` elements that trace each cell’s computed outline in white.
