A cluster of 100,000 colored points animates across the screen, moving in a repeating wave pattern with a sinusoidal x-shift and vertical bobbing. The visualization demonstrates a performance optimization in regl, a WebGL library: passing all point attributes (position, color, speed) as a single packed array per frame outperforms passing separate attribute arrays, enabling 60 fps versus the slower alternative. Using regl’s shader system and GPU buffers, the code animates points via a cubic easing function, with colors alternating between blue and orange based on parity. The data is generated procedurally, with random x, y, and speed values for each point.

AI-generated description

Passing arrays of attributes:

attributes: {
  p: () => data.map(({x, y1, dy, isB, speed}) => 
    [x, y1, dy + isB, speed]
  ),
},

is way faster than passing in seperate properties - 100,000 points at 60 fps instead of 14,000. 

attributes: {
  speed: () => data.map(d => d.speed),
  x:  () => data.map(d => d.x),
  y0: () => data.map(d => d.y0),
  y1: () => data.map(d => d.y1),
  dy: () => data.map(d => d.dy),
  isB: data.map(d => d.isB)
},

regl-ladder

This example animates 20,000 points representing race and class mobility for white and Black men, based on a rough draft of a New York Times chart. Each point moves horizontally across the screen while easing vertically between starting and ending income positions, with blue and orange dots distinguishing groups. The animation is rendered with regl, a WebGL library, using custom vertex and fragment shaders to achieve high performance. It also includes an SVG-based initial version and a canvas particle approach, both referenced in the README, and uses d3.js for scales and layout.

regl-ladder

This animated scatterplot uses WebGL to render 20,000 points representing the economic mobility of white and black men, arranged in a "ladder" comparing outcomes across income quintiles. Each dot eases along a path from its starting position to a target percentile line, with blue and orange encoding racial groups. The visualization iterates from a static SVG version through canvas-based approaches before settling on a regl implementation for performance, enabling many more points on screen. The final version optimizes rendering by passing precomputed arrays of attributes to the vertex shader and animating the points along their trajectories over time.

points

One hundred thousand points render as colored particles in WebGL, smoothly morphing between different distributions—random walks, phyllotaxis spirals, sine waves, and grids—at regular intervals. The animation uses regl to draw points and interpolate between buffer states in the vertex shader, with a viridis colormap applied per point. A control panel lets viewers adjust point radius and the total number of points.

regl-hurricane

Animated WebGL visualization of 10,000 line segments that continuously morph between different geometric patterns—a circle, then two distinct random point distributions. The code uses the regl framework with custom GLSL vertex and fragment shaders to interpolate between precomputed buffer states, cycling through three datasets in a loop. Line color shifts from blue to red based on each segment's position index, while d3 generates the underlying point data and easing functions control the smooth transitions.

regl-hot-server

A dense cluster of 100,000 points animates through looping random walks, with colors transitioning along the viridis colormap. The visualization cycles between five precomputed datasets, interpolating point positions in a WebGL vertex shader. Built with regl and React, it demonstrates a hot-reloading workflow where editing `script.js` updates the page without a full reload, using hot-server and watchify to stream changes directly to the browser.

regl-circles

Twenty thousand colored circles fall from the top of the viewport, then settle into horizontal bands based on each circle's speed and size. Two quantized scales map circle index to a target row, and a WebGL shader renders each point with a soft-edged stroke and rounded fill. The animation cycles continuously via a REGL frame loop, with position and color computed per frame in the vertex and fragment shaders using D3 scales and lodash for data shuffling.

Svelte + D3 + Regl starter (WebGL)

This example displays 100,000 colored dots of varying sizes and opacities on a WebGL canvas, with an overlay text reporting the total count. The visualization uses Svelte to manage the application state and interface, D3 for generating the data—including coordinates, radii via `randomExponential`, a warm color scale via `scaleSequential` and `interpolateWarm`, and opacities—and the regl library to render the points as a canvas-based WebGL scene. A custom regl fragment defines the dot shape with antialiasing, while blending controls the visual stacking of overlapping points.

regl-demo

A WebGL triangle rendered with regl animates its background color in a smooth, time-based loop. The vertex shader derives the triangle’s fragment color from its position attributes, producing a gradient across the shape. The example uses `regl.frame` for continuous rendering and `regl.clear` to update the background, demonstrating basic GLSL shader setup and attribute passing with the regl API.
