Current Terrain

A field of warm-white and Problem-red particles streams across a three-wave ground plane, recycling through depth while the pointer lifts a localized current from inside the landscape.

• Hero backdrops
• Section transitions
• Ambient product moments

• Three translated wave bands move coherently rather than churning in place
• Perspective projection expands near particles and compresses the horizon
• Depth wrapping happens behind the fog band for a continuous field
• Pointer lift deforms only the nearby current while the camera remains fixed
• Every control maps directly to this component's independent renderer contract
• Full-size and compact previews use the same implementation and behavior

Adaptive sampling, capped DPR and visibility-based suspension keep the renderer predictable. Test density on low-power mobile hardware before increasing it.

Pointer and touch coordinates are container-scoped; offscreen renderers stop work and pixel ratio is capped.

The visual canvas is decorative by default. Pair it with a semantic heading or description, and reduced motion holds a stable rendered frame.
