Morphon vs Pocket 3D

Sixty-three simulations from real physics, chemistry, and mathematics — running entirely on your device's GPU. Touch them. Pinch into a Mandelbrot set. Inject a vortex. Drag a magnet and watch a fractal basin re-paint. Drop pebbles into a pool and watch the waves bounce off the walls. Nothing is pre-recorded; everything you see is computed from the underlying equations as you watch. WHAT'S INSIDE • Fractals — Mandelbrot, Julia, Burning Ship, Newton, IFS chaos game, and ten construction fractals (Koch snowflake, Hilbert curve, Apollonian gasket, and more) that build up one iteration per second • Cellular Automata — Conway's Game of Life, Lenia, Brian's Brain, Forest Fire, neural CA • Reaction-Diffusion — Gray-Scott, Belousov-Zhabotinsky, Turing morphogenesis (square + hex lattice) • Fluid Dynamics — incompressible Stable Fluids, shallow water, Kelvin-Helmholtz instability with optional vortex shedding past a cylinder, non-Newtonian oobleck • Wave Phenomena — Chladni plates, Faraday waves, cymatics, animated underwater caustics • Chaos — Lorenz / Rössler / Halvorsen attractors, magnetic-pendulum fractal basins, Hénon-Heiles • Phase Transitions — Ising, XY-model, Potts, Kuramoto oscillators, percolation, bubble foam coarsening • Field & Flow — Perlin noise, curl-noise, flow fields, paint-your-own velocity fields • Growth — crystal nucleation, L-systems, real DBM Lichtenberg lightning, differential growth • Collective Behaviour — slime-mould Physarum, Boids flocking • Plus granular sand, cloth, sandpiles, Schelling segregation, small-world networks, and more INTERACTION Every simulation responds to touch in a way that's specific to it. Drag to inject dye into a fluid; pinch to zoom into a fractal; flip spins in the Ising model; drag the magnets in the Magnetic Pendulum and watch the basin re-paint. Multi-touch is supported throughout. KEEP YOUR ART Save stills (PNG) and short loops (MP4) directly to Photos, share to social, or just sit back and watch. Six color palettes including viridis, magma, plasma, and turbo apply across every simulation. NO ACCOUNTS, NO ADS, NO TRACKING Morphon collects no data, runs no analytics, and connects to no servers. Whatever you make stays on your device. UNIVERSAL & OPTIMISED Built for iPhone and iPad. Targets 60 fps on every supported device with thermal-aware downshift on older hardware. Pencil-aware on iPad: pressure and tilt drive simulation parameters where it makes sense. Open it. Touch it. The math does the rest.

Pocket 3D turns your iPhone into a proper STL viewer. Open a model, turn it over in your hand, and find out the things you actually need to know before you print it. MEASURE YOUR MODEL Bounding size on every axis, plus volume, surface area and triangle count. Everything is measured in the file's own coordinate frame, so the axes match your CAD software or slicer. Sizes are shown in millimetres, the standard convention for 3D printing. CHECK IF IT WILL PRINT In a closed mesh, every edge is shared by exactly two faces. Pocket 3D verifies that and reports the result. When a mesh is not watertight, the app withholds the volume figure rather than showing one, because on an open surface that number has no meaning. VIEW FROM ANY ANGLE One finger orbits, pinch zooms, two fingers pan. Snap to isometric, top, bottom, front, back, left or right, and re-frame at any time. MAKE IT READABLE Six model colours, four backdrops, and four shading modes: flat, smooth, wireframe and x-ray. X-ray fades the near surfaces so interior structure becomes visible. OPEN FILES FROM ANYWHERE Binary and ASCII STL with automatic format detection. Open from the file picker, your recents, or share a file straight into Pocket 3D from another app. A sample model is bundled so you can try it immediately. PRIVATE BY DEFAULT No servers, no account, no sign-up. Files are read on your device and never leave it. No analytics, no advertising, no tracking. Works with no internet connection.
