Projection Mapper: Video&Light

Projection Mapper turns any flat or multi-surface object into a canvas for
video, images, and animated light patterns.

Map custom shapes — triangles, quads, or free-form polygons — onto the
physical surfaces you want to project onto, then drag each corner into place
for a precise, perspective-correct fit. Assign a photo, a video, or a
built-in animated pattern to every shape, or group several shapes together to
share and sync one video across them.

When you're ready, switch to full-screen Present mode: on-screen controls
disappear, the display locks to your current orientation, and the screen
stays on for uninterrupted projection — just point your projector or screen
at the surface and go.

Fine-tune every mapping with a corner nudge pad, adjustable snap tolerance,
shape rotation, duplication, and a layer list for managing multiple shapes at
once. Build and save your own animated patterns in the Pattern Studio, or
pick from the built-in library. Save projects to a file and reopen or share
them any time.

Projection Mapper is completely free to use. A short rewarded ad unlocks
Present mode each time you open the app, and again every few minutes of
continued use.
