CLOUD / UNI-DECK

FLOW

Sand + water sandbox, tuned for 60fps and UNI-DECK controls.

Physics-first playground

Hybrid particles + pressure grid.

Build dams, carve rivers, test erosion, and route aquifers with a responsive simulation tuned for touch + keyboard. Quality tiers and worker-ready messaging keep the loop smooth, even with 10K active grains.

Tools

Brushes & emitters

Canvas + HUD
  • Sand/water brushes with adjustable rate + wet/dry toggle.
  • Emitters for continuous, burst, and finite volumes.
  • Terrain sculpting, drains, sponges, and rock blockers.

Simulation

Hybrid loop

Worker-ready
  • Particle hashing for sand grains + droplets.
  • Pressure grid tracks volume/velocity per cell.
  • Erosion + sediment transport tied to flow speed.

Scenarios

Exports

Telemetry ready

CSV + JSON
  • Session capture (inputs + seeds) for replay.
  • Heatmaps for erosion, pressure, and flow.
  • Screenshot + timelapse helpers for sharing.
