SURFACE FROM PARTICLES

• M camera, stir, crates or tank · one finger does the selected one
• in tank: drag to move the tank up, down and sideways · Shift+drag across the floor · wiggle to shake · let go and it springs home
• in crates: tap the water to drop one, drag one to move it
• two fingers or right-drag always orbit · scroll zoom
• V cycle the views · 1–6 pick one · 6 raw particles
• C still water · F foam · R reset the dam and crates
• B plankton · N day / night
• Q quality: 200k particles for a smoother surface, about 3.5× the GPU time (reloads)
