← Lab homeWords flowing like ocean waves with computed wrap geometry—a meditative canvas visualization powered by Pretext.
What It Does
Sea of Words transforms text into a living, breathing seascape. Individual words are rendered on a canvas and animated with sine wave motion, rising and falling as if they were ripples on water's surface. What makes this technically fascinating is that Pretext recalculates wrap geometry every frame, maintaining correct line breaks even as words move vertically. The result is a piece that feels organic and fluid while remaining typographically precise. Each word knows where its line should break, regardless of its current y-position. The demo creates a meditative, calming visual experience—perfect for understanding how Pretext measurement integrates seamlessly into animation loops without sacrificing accuracy or performance.
Technical Highlights
This scene combines real-time animation with dynamic text layout. Words are positioned on canvas with sine wave easing applied per-frame, creating smooth undulating motion. Pretext's wrap geometry engine recalculates line-break positions after each animation frame, ensuring that despite vertical displacement, words still respect their proper line boundaries. The technical challenge lies in coordinating three systems: animation state, text measurement, and canvas rendering. Traditional approaches would either ignore wrap integrity during animation or rely on expensive DOM reflections. This demo proves that by computing geometry separately from rendering, both animation smoothness and typographic correctness are achievable simultaneously without performance compromise.
Pretext APIs Used
| API | Purpose |
|---|---|
| Wrap geometry | Calculate line breaks as words animate vertically |
| Canvas text rendering | Draw individual words with computed positions |
| Real-time measurement | Update layout each animation frame |
| Line breaking algorithm | Maintain correct breaks despite vertical displacement |
How to Try It
Open the Sea of Words demo and let it run. The animation is continuous and hypnotic. Watch how words flow around each other in wave patterns while maintaining proper line structure. Notice that despite constant motion, no word appears in the wrong line or breaks unexpectedly. This is Pretext handling the geometry while your browser's rendering pipeline handles the visuals. The scene works on all devices, though larger screens reveal the full wave patterns more clearly. Spend a moment watching—this demo is meant to be experienced rather than analyzed.
