This example renders a colorful Sierpinski triangle fractal using the HTML5 Canvas API. The visualization recursively draws the triangle to a depth of five, with each smaller triangle assigned a random bright hue via the `hsl()` color function. It uses basic Canvas drawing methods like `moveTo`, `lineTo`, and `fill`, and the display automatically resizes with the window.

AI-generated description

Sierpinski Triangle

A fractal rendering of the Sierpinski triangle using HTML5 Canvas.

The triangle is drawn recursively with a depth of 5. Each smaller triangle is colored randomly with a bright hue.

The canvas resizes automatically when the window is resized.

Sierpinski Triangle Example

This example shows a Sierpinski triangle fractal rendered as an interactive tree-like structure on a Canvas element. The fractal is drawn with recursive triangle subdivision, and the branching depth changes dynamically based on the mouse position. The code uses the Canvas 2D API with `beginPath`, `moveTo`, `lineTo`, and `fill` methods to draw triangles. It accommodates high pixel density displays by scaling the canvas resolution using `window.devicePixelRatio`. The mouse event listener recalculates the depth from the cursor's horizontal position, then clears and redraws the entire fractal.

Sierpinski Triangle

This interactive Sierpinski triangle fractal renders recursively to a canvas, with its recursion depth controlled by the mouse’s horizontal position. The visualization shows how a geometric fractal pattern changes complexity as the mouse moves from left (shallow depth) to right (deeper recursion). The code uses the Canvas API’s `clearRect`, `beginPath`, and `fill` methods to draw triangles, and scales the canvas dimensions by `window.devicePixelRatio` for high-resolution displays. The fractal is generated from a fixed initial triangle with depth up to 10 based on mouse X position.

Fork of Sierpinski Triangle

This interactive fractal displays a Sierpinski triangle that divides into recursively smaller subtriangles on an HTML5 Canvas. The branching depth changes dynamically based on mouse position, ranging from zero to ten subdivisions. The code uses the Canvas API’s `getContext` and `fill` methods, with `devicePixelRatio` to ensure sharp rendering on high-resolution displays. Moving the mouse horizontally triggers a `mousemove` event, recalculating depth and redrawing the triangle with `clearRect` and recursive function calls.

Sierpinsky Pyramid

This example visualizes a 3D Sierpinski triangle as a pyramid built from smaller tetrahedra that align with the faces of the outer shape. Animated via a recursive generation process, the scene renders with Three.js using WebGL and canvas, while OrbitControls enable interactive rotation. The code constructs pyramid geometries and materials with directional and point lights, casts shadows onto a ground plane, and applies ambient lighting. A green background and double-sided white materials highlight the fractal’s structure as the camera orbits freely.

Fractals in D3 and Canvas: Sierpinski Gasket

This example visualizes the construction of a Sierpinski gasket, a fractal pattern, by iteratively layering scaled-down copies of a canvas. Each iteration creates a new canvas, scales its context by half, and draws three copies of the previous canvas into the corners, replacing the old one every second. The animation runs for 14 total iterations using D3 v4 to select elements and append canvases, while the drawing and scaling operations rely on the Canvas API’s `scale` and `drawImage` methods. The original canvas is filled green using `fillRect`, and each new canvas labels its iteration number with `fillText`.

Trembling triangle #2

An animated triangle on a canvas trembles and morphs as it fills with shifting, warm-colored bands. The rendering uses a D3 v4 timer loop to drive the shape’s jitter, with the triangle’s edges recursively subdivided to create fractal depth. Each frame, the canvas is cleared, and ten offset triangle paths are drawn in sequence with semi-transparent fills, producing a shimmering, layered effect. The code employs `d3.randomNormal`, `d3.scaleLinear`, `d3.interpolateWarm`, and the Canvas 2D API to generate the motion and color.

fractal

This interactive fractal experiment uses recursive circle drawing on an HTML5 Canvas to generate branching, tree-like structures. The visualization responds to mouse movement, with cursor position controlling the fractal’s scale, branch angle, and recursion depth. The code defines a `drawGeometry` function that recursively draws circles, translating and rotating the canvas context at each step, while a `flip` parameter alternates branch direction. Rendering is handled directly through the Canvas 2D API, with event listeners triggering redraws on mouse move. No external libraries are used, relying solely on native browser canvas methods like `ctx.arc`, `ctx.translate`, and `ctx.rotate`.

Julia Set

This example renders a Julia set fractal on a canvas, using a teal-to-black color scale to depict iteration counts across a 360×360 grid. The visualization animates smoothly by tweening a pixel index through Svelte’s `tweened` motion, recalculating the fractal values as the index progresses. Each pixel is drawn as a 1×1 rectangle via the Canvas API, with Svelte’s context system coordinating registration and invalidation between the `Canvas` and `Pixel` components, while d3 scales map coordinates and iteration values.
