Pointfield Mobile

Turns your camera, a video or a photo into a field of glowing particles you move with your fingers. Pointfield Mobile redraws the live image as up to about 260,000 particles. Each particle takes the colour of the image beneath it. Fine detail drops out; shape, light and colour stay. It works best with simple subjects and strong contrast: a face against a bright window, a silhouette, bold colours. A short tutorial opens when you start the app and shows each gesture on the live image. Open it again any time from the Tutorial button. Gestures - Swipe: swirls the particles. A fast swipe throws them. - Hold a finger still: the particles gather to it. - Tap: a wave spreads from the tap. - Draw a circle: a vortex. Keep circling: the whole field orbits. - Hold, then drag: paints the particles along your finger. - Two-finger tap: explosion. Two-finger slide: wind. Two fingers drawing a circle: tornado. - Three-finger tap: implosion. Three-finger hold: drain. Three fingers down or up: fall or rise. - Tilt the phone: the particles pour downhill. - Shake: resets the field. Reset is also a button. Record a clip with the Record button and save or share it. Recordings have no sound. Sources: the front or back camera, the included sample video, or a supported video or photo from your library. Works in portrait and landscape. The Controls panel has brightness, point size and density, and how the particles move. All processing happens on your iPhone. Nothing is uploaded.
