Phyllotaxis II

Voronoi Test (N=2)

The example shows a Voronoi diagram computed from two fixed points, with each cell and its corresponding point circle filled using the same color from `d3.scale.category10()`. Using d3.v3 and SVG, the code applies `d3.geom.voronoi` to generate the cell polygons, then renders them as `path` elements with a hover effect that increases fill opacity. The circles are positioned via `transform` translations, and both layers receive black strokes from the shared CSS rule.

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.

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.

Voronoi Tessellation

This interactive Voronoi diagram shows how a set of one hundred random points partitions a 960-by-500 SVG canvas into polygonal cells. Moving the mouse repositions the first site, causing the diagram to recompute dynamically with the red polygon, black links, and white site markers updating in real time. Built with D3 v4 and the d3-voronoi library, the example renders polygons as SVG paths, links as lines, and sites as circles, with all geometry recalculated on each mouse move.

Toric Voronoi

This example demonstrates a Voronoi diagram on a torus, where 300 random points create cells that wrap seamlessly across the canvas edges. It shows how the cell structure repeats across a virtual cylinder in both horizontal and vertical dimensions, with the interactive site highlighted in red. The code uses d3.voronoi to compute the diagram, duplicating each site into eight shadow copies to handle the toroidal topology, then filtering links between shadow copies. Rendering is done via Canvas 2D context, with polygons, links, and sites drawn as separate paths.

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

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 Clipping

Two points generate a two-cell Voronoi diagram clipped to the SVG canvas. The example shows how `d3.geom.voronoi` clips its output polygons using the `.clipExtent` method, with each cell rendered as an SVG path and each input point as a circle. D3.v3’s `category10` scale colors the cells and points. Hovering a path slightly raises its fill opacity, though no other interaction is implemented.
