Splat Equation

Here you program them with math: each splat gets two numbers, u and v, and your equations x, y and z turn them into its place, while hue (or r, g and b) gives its color. Time t runs from 0 to 2π, so the shape can move.

Tap it to play one cycle of t and watch the shape move. Pick a sphere, a torus, a Möbius strip, a seashell, a trefoil knot, a wave, a spiral galaxy or a Klein bottle in the Splash tab, or type your own, such as z = sin(u + t). Under Splats, Solid shows a clean surface, Fine a finer one, and Dots every splat on its own. The Splash Manual explains the whole language.
