Mapping shapes onto surfaces

The dark canvas is the projector's picture. Every shape you place on it is warped so it lands on a real surface: a wall panel, the side of a box, a picture frame, a window.

At the top: the menu (☰), My Projects (folder), the projector button (red = not connected, green = connected) and the purple Play button. Undo/redo and zoom sit top right; your shapes line up along the bottom.

Tap + (or tap an empty spot on the canvas, then + New Shape, to place it right there) and pick a shape:

• Square — four corners. The workhorse for anything flat: walls, boxes, frames, signs.
• Circle — plates, drums, lamps, round windows. Edges swaps the corner pins for edge handles to make ovals; Sphere bulges the visual like a ball.
• Text — type a word; the visual plays inside the letters. Eight fonts.
• Outline — draw any shape with one continuous finger stroke.
• Cube — the three visible faces of a box in one go, already joined at the edges.
• Box — the inside of a room or corner: a back wall plus up to four sides, sized with Width, Height and Depth.
• Shape Cutout, Depth Detection, Transparent PNG, Mapping Background — → photo-based tools (Pro). Shape Cutout is on iPhone and iPad only.

• Select: tap a shape on the canvas or its thumbnail along the bottom.
• Warp: drag a corner pin. Pins stay the same size however far you zoom.
• Move: drag inside the selected shape. Dragging outside it pans the canvas.
• Rotate and scale: use the round handles at the top-right and bottom-right corners.
• Zoom: pinch the canvas (up to 30×) or tap the magnifier to jump between close-up and the whole picture.
• Undo/redo: the arrows at the top appear as soon as there is something to undo (up to 20 steps).

With Snap Corners on (menu ☰, on by default), a corner you drag near another shape's corner jumps onto it with a little click. Let go and the two corners weld: the shapes now share that point and move, rotate and scale together — perfect for boxes, steps and tiled panels.

To separate them, select the shape, tap the welded corner and tap Remove Weld. Turning Snap Corners off stops new welds but keeps existing ones.

Select a shape and its tools slide up along the bottom (scroll sideways for more):

• Duplicate / Delete / Hide — Delete has no confirmation, but Undo brings the shape back.
• Rounded — round any of the four corners with a radius slider.
• Add Point — drag the dot in the middle of an edge to add a point, for steps, arches and odd outlines. Tap a point to delete it.
• Bend — curve an edge with the Curve slider and its handles, for pillars and curved signs.
• Flip — rotate the visual 90° or mirror it inside the shape without moving the shape.
• Edit — change a Text shape's words or font.

1. 1

   Tap + → Cube. A 3D cube appears.

2. 2

   Drag on the cube to move it and drag beside it (or use the joystick) to turn it until it matches your box. Drag single corners for the last bit.

3. 3

   Tap OK. The cube becomes three welded faces that you can fine-tune like any other shape, and give each its own visual in Play.

Shapes along the bottom are your layers. Long-press a thumbnail and drag it to reorder; hidden shapes look dimmed. Want new shapes to appear at the start of the list instead of the end? Turn on Inverted layer order in General Settings.

• Show Border — draws a thin border around the whole projected picture, handy for lining up the projector.
• Snap Corners — corner snapping and welding.
• Mini-map Thumbnails — thumbnails show each shape in its place on the canvas.
• Mapping Style — how shapes look while you map, separately for the phone (Device) and the projector (External): Fill, Grid or Checkerboard, colours, grid size and pin size.
• General Settings — projector orientation (for a projector mounted sideways or upside down), Mapping Template export and more.
• Return Home — autosaves and goes back to Home (or saves a named project first with Pro).

• Fix the projector in place first. If it moves even a little, every corner moves with it.
• Turn off the projector's keystone and auto-keystone; let Lazy Lighting do the correction.
• Map in a dark room. Do the rough shape zoomed out, then pinch in to place each corner exactly.
• Map the biggest surfaces first, then weld smaller pieces onto them.
• For a busy scene, a Mapping Background photo lets you trace surfaces on the phone instead of looking up at the wall.
