Bengala: Projection Mapping

Bengala is a projection mapping studio for iPhone and iPad. Connect a projector, drag the corners of a shape onto a window, a door, a pumpkin or a wall, and choose what plays inside it. The first setup takes a few minutes. HOW IT WORKS 1. Plug in a projector with an HDMI adapter, or start AirPlay screen mirroring. 2. Add a shape: rectangle, circle or stencil. A rectangle takes extra corners for odd surfaces. 3. Drag its corners until it sits on the real object. The picture bends to fit, so a flat video still looks straight when the projector sits at an angle. 4. Pick an effect, a photo, a video or a color. The preview on your phone shows what the projector shows. You can build everything before you plug anything in. EFFECTS SORTED BY THEME Effects are grouped by theme: animals, illusions for doors and windows, party, fire and nature, space, neon and abstract. Christmas goes first from mid November to early January. Every animal is rendered in 3D, and so are some Halloween effects. Effects download when you tap them, so the app stays small and new ones arrive without an update. You need a connection the first time you use an effect. After that it plays offline. WHAT A SHAPE CAN SHOW - A looping effect - A music effect that moves with the sound around the phone - Your own photo or video - A plain color or an animated color - One shape at a time, or the whole canvas Use one shape per surface: the window, the door, the pumpkin on the porch. Each keeps its own content. PROJECTING THROUGH A WINDOW? Projecting from behind frosted film or a shower curtain flips the picture. Turn on Mirror output and it reads the right way for the people outside. IN THE EDITOR - A new project opens with an effect already playing - Pinch to zoom in and nudge a corner into place - Undo and redo - Guides: while you move a shape, the projector shows its grid. A second after you let go it fades. Tap the empty canvas to hide the outlines too - Present mode: the phone goes dark, the projector keeps playing - Stencils: pick a silhouette, or bring a PNG with a transparent background (Pro) and its outline becomes the shape WORKS WITH Any projector with an HDMI input, through a Lightning or USB-C adapter, or any projector or TV that supports AirPlay. HDMI is sharper and has less delay. Use a dark room. For windows, we suggest at least 300 ANSI lumens. A color lamp in Apple Home, if you want one. Effects with a lamp icon change its color at the right moment. A NOTE ON FLASHING Some effects flash or strobe. If you or someone watching is sensitive to flashing light, check each effect on your phone first. FREE AND PRO Free: 1 project, a set of free effects (Light Drop lights a lamp), the Pulse music effect, and a small Bengala watermark that drifts across the projection. Pro: unlimited projects, every effect, no watermark, every stencil shape and your own PNG stencils, every animated color, and import from the Files app. New 3D effects are added regularly, and Pro includes them.
