How this water mode feels
Water mode lowers harsh fade and holds swirl at a moderate level, so strokes keep drifting like a wet sheet instead of breaking apart after one pass. Bloom stays on at a low setting for soft highlights, not glare. It is still a real-time dye field, not a swimming pool solver.
For every preset on one canvas, use the main WebGL fluid simulation.
- Longer lasting density for readable trails
- Moderate swirl so eddies stay smooth
- Cooler color bias when colorful mode is on
- Low, soft bloom instead of hard glare
Tips for water like strokes
Use a medium brush and slower motion for wide, rolling currents. Short flicks add small ripples instead of long streaks. Raise quality if your device holds 60 FPS without trouble, and drop it on phones that start to hitch.
Learn what the sliders do
Fade speed and swirl map to density and vorticity inside the solver. The fluid simulation controls guide maps each dock slider to what changes on screen.
Questions
It is a real-time WebGL fluid with water tuned settings. It shows convincing wet motion for play and learning. It is not a lab model of oceans, pipes, or tanks.
Yes. Paint with one finger. Auto quality can step down on its own if the device needs it, so the motion stays smooth instead of stuttering.
Open the live simulation on the homepage, or tap Try live in the header from any page on the site.
Water mode biases the live palette toward cooler tones while colorful mode is on. You can still pick a custom color from the dock.
Yes. Pick a custom color on the dock, or turn Colorful off under Advanced to lock the field to one hue.
